[Tinyos-help] compiling error !!!

[fatima zohra]

hello,
i tried to compile an application (Hierarchical Tree Construction, HTC) by 
using Tossim simulator in XbunTOS 2.0.
i used the command "make pc" and this is my error message:
 
 
Makefile:3: /opt/tinyos-2.x:/opt/tinyos-1.x/apps/Makerules: No such file or 
directorymake: *** No rule to make target 
`/opt/tinyos-2.x:/opt/tinyos-1.x/apps/Makerules'.  Stop.
 
i had the same message by using "make micaz sim"
 
in the application makefile there is include $(TOSROOT)/apps/Makerules
with TOSROOT = /opt/tinyos-2.x
 
i changed my Makefile like the Blink application one (which was compiled 
successefully) by using   include $(MAKERULES)
then, i get this messages
 

HTC.nc:19: component Main not found
HTC.nc:19: component GenericComm not found
In file included from HTC.nc:19:

TreeBuilderM.nc:18: interface ReceiveMsg not found

so, i which i can find a solution for this problem.
your help will be greatly appreciated.

RE: [Tinyos-help] Running tinyos 1.x and 2.x simultaneously

[fatima zohra]

hello,
yes, i guess you can.
actually i have installed XubuntOS which is composed by Ubuntu 7.0 and TinyOS 
2.x but i found both TinyOS 1.x and TinyOS 2.x.
However, you should be aware about the version you want to use and set up your 
environnement variable for this version.
 
Best regards.

Hello,to solve this problem you have to add the "." to your CLASSPATH 
variable.for a temporal use, you can type: export CLASSPATH=:.:$CLASSPATH if 
you want to add it permanently you open your bash file, look for your CLASSPATH

[Tinyos-help] implementation of Directed Diffusion Protocol

[fatima zohra]

hello every one,
i am here to ask you if there is any existing implementation of the Directed 
Diffusion Protocol (it's a protocol for data dissemintion in wireless sensor 
networks which uses gradients). i am looking for any existing code in TinyOS.
if anyone can help me to find it, i'll be so grateful.
Best Regards.

thanks for the link,
i found the implementation, but there i a couple of problem:
1st: i found a "modified" version od Directed Diffusion protocol (DD) which is 
one push phase. actually, i am looking for the original one , the first one : 
two push diffusion.
2nd: the link you gave to mespeak about CVS. having no idea about what it could 
be (even after some readings about it) i don't find the way to download the 
whole implementation protocol, unless, i open each directory/ 
sub_directory/../file then look for the last version to download it (one by 
one).
 
so, do anyone know how to use this CVS feature? moreover, has anyone another 
code implementation for the DD protocol ?
 
your help will be kindly appreciated.
 
Best Regards.

i am facing the same problem: looking for Directed diffusion protocol which
can work with tossim.
all what i found is the tinydiff code in this address:

if you don't have it yet, this could be helpful. but since now, i couldn't
run in on Tossim.

Re: [Tinyos-help] Tossim problem..

[fatima zohra]

hello,
because u are using Tinyos 2.x not tinyOS 1.x so "make micaz sim" would work
(other wise , u have to use "make pc" instead)
now, the right command (i gues) is ./main.exe "number_of_simulation_nodes"
however, you can add some options like this example:
 ./build/pc/main.exe -t=60 -r=lossy -rf=cells-diamond.txt 10
-t=60 : time period of simulation (60 sec)
-r=lossy : type of radio communication
-rf="file" : the reference to a file containing a topology
10 : number of nodes in simulation
 you can look for further details in tutorials.
Best Regards

[Tinyos-help] publish/subscribe implementaion

[fatima zohra]

Hello,
i am looking for an implementation of any publish/subscribe protocol.
actually, i need it to implement the Directed Diffusion Protocol.
However, i've already found a code in sourceForge CVS (called TinyDiff) but
it doesn't help me that much.
so if anyone knows about other publish/subscribe implementations (or even
other Directed Diffusion code), thanks to send me the corresponding link.

[Tinyos-help] NIDO vs TOSSIM

[fatima zohra]

hello,
can anyone tell me the difference between NIDO and Tossim. it seems that
they are two separate simulators... according to what i read in lesson 5 and
lesson 11.
Actually, i have to implement a protocol using Tossim. but during all this
time i used "make pc" to compile, then execute several existing codes (in
tinyOS Contrib).
now, i have a small confusion, and i think that Nido isn't a complement of
Tossim.
am i right ? if so, what's the difference.
thanks in advance.

[Tinyos-help] what's the problem with attribute ((packed))

hello,
while reading the TinyOS programmation manual
here,
i came across this important Hint :

*Programming Hint 14: Never, ever use the "packed" attribute.*


can anyone explain to me why is it so important to notice this problem ?? is
it a big issue if we use packed attribute ?

thanks in advance.

[fatima zohra]

hello,
thanks for both of you for your reply.
however, i'm still confused.
actually my code will be use for simulation with Tossim; i have no real
motes to implement. so, there is no precised platform to use.
is it still a problem to use this "packed attribute" only for simulation
purpose?

Best Regards.

Re: [Tinyos-help] what's the problem with attribute ((packed))

[fatima zohra]

Hi Urs,
let me thank you for your clear response. now, i can see the difference much
better.
actually, the main reason i asked about "packed attribute" is that; i found
a source code in tiny contrib ( TinyDiff application) where they use packed
attribute. and i wonna use this code in order to implement the Directed
Diffusion protocol but only for simulation purposes. and once i read the
hint, i got confused.

i would like to reply to "Tiny User" about "having some experience with
Tossim" i am,  actually, new either with tinyOS and Tossim. i am trying
to implement a protocol using Tossim. so i am still learning.
but we can help each other, just send your problem and i'll see if i (or
someone else from the tinyOS Help list) can response.

best regards.

i want to know if there is a method for generating "periodic and random"

i am still having small confusion about the way we can define an attribute.
Once the packed attribute shouldn't be used, can you tell me what is the
best way to change this declaration:

#ifndef _ATTRIBUTE_H_
#define _ATTRIBUTE_H_

typedef struct {
  uint8_t  key;  // key
  uint8_t  op;// operator as defined in ..
  uint16_t value;  // Value

} __attribute__ ((packed)) Attribute;

typedef Attribute *AttributePtr;

#endif

[Tinyos-help] problem with TOS_BCAST_ADDR !!!

[fatima zohra]

Hi,
i have a small problem when I send a diffusion message using TOS_BCAST_ADDR
i wonder if TOS_BCAST_ADDR can send the packet to all nodes even if they
aren't nieghbors to the sender node ???
to be clear; this is my network topology :

1:2 1:3
2:4 2:5 3:5 3:6
4:7 5:7 5:8 6:8
7:9 8:9

however i get many messages like this one  :

3: receiveInterestMessage: got INTEREST: sink: 1 seq: 0 prev: 4 ttl: 9

which means that node 3 receives a packet from node 4 while there is no
"direct" link between these two nodes !!!

can anyone tell me if this problem may be caused by TOS_BCAST_ADDR 
thus, how can I fix it ?

thanks a lot.

Re: [Tinyos-help] problem with TOS_BCAST_ADDR !!!

[fatima zohra]

Hi Paul,
thanks for your fast reply,
so, for my application (which is tested only by Tossim) there is no "real"
physical neighbors.
in this case, is the diffusion still doing the same procedure as you
detailed ? if it does, should I change my packet.addr from TOS_BCAST_ADDR to
a list of node's neighbor (so i have n packets to send ?? or there is
another way to handle this issue ?
i even thought about broadcasting the packet then filter it at each node
receiver !
your help will be kindly appreciated.

[Tinyos-help] HELP : broadcast msg is received by nodes they aren't sender's neighbors !!! how to handle ?

[fatima zohra]

Hi,
i am using tinyos1.x with Tossim
i have an urgent problem to fix.
i am using TOS_BCAST_ADDR to send a packet to every neighbor node.
however, my packet is also received by other nodes which they aren't
neighbors to the sender node.

to be clear this is an example :

TOPOLOGY :

2:4   2:5
3:5   3:6
4:7   5:7
5:8   6:8
7:9   8:9

when i send for instance a broadcast from node 3 (neighbor to nodes 1, 5 and
6 only) some other nodes (4 ,2 even others) can receive, then "use" this
message.

so, my question is : doesn't tinyos/Tossim take in consideration the network
topology to broadcast one packet to exactely the concerned neighbors ?
if it doesn't, it means that we should make a control after every received
packet ( IF the receiver isn't a sender neighbor THEN drop the packet)
and this isn't "easy" since we don't know yet our topology ( it's given only
when simulating).

your fast reply will be kindly appreciated.
best regards.

[Tinyos-help] urgent : problem when turning off a mote !!!

[fatima zohra]

Hello,
please i need your help for urgent,
i want to turn off a set of motes in my network (i am using TinyOS 1.x with
Tossim for simulation) for this, i just call StdControl.stop()
however, i notice that these motes are still receiving and sending packets.
so, whether, i use the wrong command to turn off my motes  in this case
what should i use as commands ?
  or there is a problem even after turning off the motes  what can it
exactly be ?

your fast reply is kindly appreciated.
best regards.

[Tinyos-help] about packets loss rate

[fatima zohra]

hello everyone,
i have an urgent problem to solve,
i am wandering if there is any module which calculates the loss rate in the
network.
i am using tinyOS 1.x and Tossim for simulation.
if no intefacre already exists, what is the easiest way to get the "average
packet loss rate" in the whole network ( it's a bit difficult for me since
i'm new in tinyOS and Tossim)
if anyone can help me regading this issue, i will be so grateful.
your fast reply is kindly appreciated.
best regards.

[Tinyos-help] help please : turn off mote & packet loss rate ?

[fatima zohra]

Hi,
please i need your help and it's urgent

1) i want to turn off motes (on Tossim, TinyOS 1.x)... for this, i use
StdControl.stop() where i stop all the components (timer, genericComm,
flash)
except Timer.stop() i couldn't find how to stop the other componnents
(GenericComm and flash)... i get some error messages while compiling. i
searched in tutorials and tinyOS-Help posts and it didn't help me much.
please can anyone tell me what are the components i should stop in order to
turn off motes (i.e. stop sending and receiving messages) and how ?

2) i want to know also, if there is any way to calculate packet loss rate ?

i do need your help;
your fast reply is kindly appreciated.

[fatima zohra]

Thanks Omprakash for your reply,
may be i miss something... so this is the whole situation.
i am using a protocol which sends periodic messages ( so i can calculate the
number of the packets sent bu each node),
however, how could i calculate the number of packets that were not received
( i have no ACK reply). is there any interface which does this ?
your help is kindly appreciated.
thanks in advance

Re: [Tinyos-help] Discovering Neighbors

[fatima zohra]

hi everyone,
i think what Nahr said has a sense.
we can have a one way communication.

the example attached can explain the situation. (one node can be in the
range of its neighbor but this latter can't receive that node's packets)
just because they have different radio range (for example).
hope, this makes it clear.

actually this isn't my scenario;
here is an example of my protocol mechanism:
we assume Node1 neighbor of nodes 2 & 3, and these two nodes are neighbors
of source S (S will send 10 msgs for example)
if 3 crashes so node 1 won't receive any more packets from 3. which means if
S sends messages (from numSeq = 5 to 9)  node A will never notice that he
missed the 5 last nodes (because he doesn't communicate with S directly ,
and node 3 is turned off for ever and node 2 won't help him to know what
node 3 lost as messages (from S or other sources) because seq number is
unique and different for each node (the 5th seqNum for node 2 may be the 1st
message of the source S)
now i wonna to calculate packet loss rate in my network since i have a set
of nodes who crash and will lose some sent messages.
am i clear now ? if yes, how to handle this situation.
thanks in advance.

because node 3 will forward what the source is sending in order to reach the
sink (let's say for example sink = node1 to make it easier)

i mention in addition of what was said that: this simulation is done to
study the behavior of the network after some nodes crash.
so, first i choose some faulty nodes, then , turn them off for the rest of
simulation (they won't receive any packet in the future). in the end of my
simulation, i calculate my packet loss rate (i.e number of sent messages but
not received by faulty nodes once they are stopped).
is it clear now ?
Thanks for your help,

that's it,
but S-->3-->1 is just a piece of my topology (i just noticed it to clarify ,
my topology is larger than that).
let's work with this small scenario.
what's the way to find the packet loss rate ?

[Tinyos-help] problem when compiling !!!

[fatima zohra]

hello,
i have this warning about 30 times in my compilation:

/opt/tinyos-1.x/tos/platform/pc/PowerStateM.nc:953: warning: overflow in
implicit constant conversion
can anyone tell me what's wrong ?
in addition, i notice that it is impossible to send any packet . here is
what i got by using dbg messages :

2: TxMan: CommSendMsg: FAILed to send packet down to link layer!!!

I wonder if this warning can affect the packet sending.
any help will be kindly appreciated.
best regards.

hi Mihael,
it seems really weird because i already checked the PowerStateM.nc file and
there are only 400 lines of code. so there is no existence of line 953
!!! does it make any sense for you ?

[fatima zohra]

hi all,
just to thank everybody who helped me to solve the problem about packet loss
rate.
my solution is working. i used some dbg messages to notify each packet loss;
then programmed a small script which calculate the number of occurence of
this "notification".
Hopefully, it works well.

I have the following receives in my application. The configuration file has the following:

FaultM.Bcast -> Bcast.Receive[AM_COUNTMSG];
Bcast.ReceiveMsg[AM_COUNTMSG] -> Comm.ReceiveMsg[AM_COUNTMSG];
multihopM.ReceiveMsg[AM_SURGEMSG] -> Comm.ReceiveMsg[AM_SURGEMSG];
The AM_TYPE of AM_SURGEMSG is 17 and that of AM_COUNTMSG is 24.
My Module file is as follows:
Uses {
interface Receive as Bcast;
interface Receive as multihopM;
}
event TOS_MsgPtr Bcast.receive(TOS_MsgPtr pMsg, void* payload, uint16_t payloadLen) {
code.}
event TOS_MsgPtr multihopM.receive(TOS_MsgPtr pMsg, void* payload, uint16_t payloadLen) {
..code.}
I know that the two receives are not handled properly. I read the documentation of tinyos 2.x by Dr. Philip Levis but I didnot quite understand how to fix this in tinyos1.1.15.
Please help me understand this and point out what I can do to handle the receive properly. My compiles well without errors and only gives the above mentioned warning. Thanks in advance and I would greatly appreciate any help.

Regards,
Fatima

[Tinyos-help] Photo Sensor -TelosB

[Fatima Zohra]

Hi All,

I am using TelosB motes and TinyOS 1.1.15. What sensor readings is
SurgeTelos giving. I checked DemosensorC and it is supposed to give
photo-sensor readings. When I shine light on the telosb motes. I dont see
any variation in the reading? How do I read the accurate light readings
using TelosB motes.

Any help/ suggestions will be greatly appreciated. I really help to complete
my project. Thanks in advance and happy holidays.

Cheers,
Fatima

Re: [Tinyos-help] Photo Sensor -TelosB

[Fatima Zohra]

Hi,

Thank you for the reply. Thats right. DemosensorC is not wired to photo
sensor. I wired the Hamamatsu PAR sensor to my application and now it works
fine.

HamamatsuC as Sensor;

Main.StdControl -> Sensor;

AlgoM.ADC -> Sensor.PAR;


Thanks,
Fatima

That sounds right. Not all Telos nodes have the photo sensor, after
all...

[Tinyos-help] Telos mote: Surge Application GUI

[Fatima Zohra]

Hi
 
 I am trying to run SurgeTelos on telosb motes. I programmed the motes as following
make telos reinstall.0 for the base station and 
make telos reinstall.n for other motes.
 
After running the following commands in opt/tinyos-1.x/tools/java export [EMAIL PROTECTED]:telos
java net.tinyos.surge.MainClass 125
 
I get the sensor network topology window but only base station mote is displayed. No other motes appear on the screen. The LEDS on the motes other than base station motes dont glow.
 
Also if I invoke the serial forwarder and then run "java net.tinyos.surge.MainClass 125" I get the following error

[Tinyos-help] TelosB Java.net Error

[Fatima Zohra]

Hi Cory,
 
I had e-mailed earlier too regarding the problem I am facing with surgeTelos. I have seen many tinyos Help archives which state the same problem but no one has given a solution. I am using tinyos 1.1.11. 
unset MOTECOM   java net.tinyos.sf.SerialForwarder -comm [EMAIL PROTECTED]:telos

Re: [Tinyos-help] TelosB Java.net Error

[Fatima Zohra]

Hi Phil,
 
Thanks a lot for your prompt reply. I had norton's firewall. I disabled it and ran   java net.tinyos.sf.SerialForwarder -comm [EMAIL PROTECTED]:telosjava net.tinyos.surge.MainClass 125

 
Serial Forwarder uns and shows increase in packets. Main class gives a display but there is no increment in packets displayed. I am sure it has to do something with the sockets. Can you suggest what I should do to get the network topology correctly?

 
I really appreciate your help. Thanks a lot. Please tell me how to resolve the above mentioned problem.
 
Regards,
Fatima

[Tinyos-help] SurgeTelos

[Fatima Zohra]

Hi All,
Has anyone sucessfully run SurgeTelos on TelosB motes Using Tinyos 1.1.11.
 
When I run java net.tinyos.surge.MainClass 125 after invoking serial forwarder I get a sensor network topology screen with Mote 0 showing. But It displays no data. Although serial forwarder shows increment in data packets. Also MultiHop does not occur. Motes other than base station don't seem to transmit data at all. The Tx, Rx LEDS dont glow at all.

 
Please Help! I really need to complete my project. Any suggestions would greatly be appreciated
 
Thanks in Advance,
Fatima
