[Tinyos-help] Porting code from tinyos 1.x to tinyos 2.x
Hi all, I want to upgrade a code written in tinyos 1.x to 2.x. I would like to know what are the changes made in the following" 1. RadioCRCPacket 2. TOS_UART_ADDR (I know it is no more in the AM file. The help says to use SerialAMSenderC component to send to a serial port. But I want the address value for a operation like port_address!=TOS_UART_ADDR ) pl let me know if you need further info. Thanks a lot, Psundar ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
Re: [Tinyos-help] Porting code from tinyos 1.x to tinyos 2.x
Thanks a lot. That helps. Are familiar with the struct Tos_Msg in tinyos 1.x? I learnt that Tinyos 2.x doesnt has replaced tos_msg with message_t and prevented direct access of certain member functions. For certain variables like tos_msg->group, tos_msg->type, it provides functions like AMPacket.group(tos_msg) and AMPacket.type(tos_msg). It doesnt provide interface functions for all. 1. Do you know how to retrieve the equivalent of tos_msg->crc? I know the equivalent is stored in cc2420_metadata_t->crc for micaz (message_t->message_metadata_t->cc2420_metadata_t->crc). But I dont know how to retrieve it in my code which has only message_t defined? 2. What does tos_msg->addr represents? the source/destination address?

[Tinyos-help] Porting code from tinyos 1.x to 2.x
Hi All,
Im trying to port a code from tinyos 1.x to tinyos 2.x. Can anyone help me
with the following questions?
1. Whats the equivalent of *BareSendMsg*, *RadioCRCPacket* in tinyos 2?
2. *Random.init()*, *Leds.init()* and *Timer.StdControl()* is not there in
tinyos 2. How to port those functions from 1?
3. How to get *Tos_Msg tos_msg->ack/crc/length* in tinyos 2? The equivalent
to Tos_Msg is message_t and they stopped allowing direct access to some of
the member functions in Tos_Msg. In tinyos 2.x, they have moved those
variables into a more platform specific structures. you have to navigate
like ("message.h")*message_t->*("platform_message.h")*message_metadata_t->*
("cc2420.h"/"cc1000.h"/..)*cc2420/cc1000/..->ack*. But I dont know how to
import it. when i do the folowing,
(make micaz sim)
*message_t * tos_msg;*
*message_metadata_t *msg_meta = tos_msg->metadata;*
*cc2420_metadata_t *cc2420_meta = msg_meta->cc2420;*
It gives error saying that cc2420 is not a member of the union.
For certain members like tos_msg->type/group, it provides a interface
AMPacket to access them by commands like AMPacket.group(message_t *) etc.
But when I do the following it gives error saying that comand has to be
called with 'call'
type=AMPacket.type(tos_msg) or if(AMPacket.group(tos_msg)==TOS_GROUP)
Awaiting your earliest reply.
Thanks in advance,
Pratibha

Re: [Tinyos-help] Porting code from tinyos 1.x to 2.x
Thanks Philip. I did check on that and corrected some of them already.
I found this to be useful too:
http://enl.usc.edu/~jpaek/porting_tinyos_1_to_2.html
Other than those, I figured out ActiveMessageC is the equivalent of
RadioCRCPacket and we have to use interfaces like Packet,
PacketAcknowledgements too to retrieve some members of message_t.
BUT, I havent figured out how to access CRC of the message. If anyone knows,
pl reply.
Thanks,
Pratibha

[Tinyos-help] Neighbours get deleted in cldp
Hi, Im running cldp_gfr code. Im using a 8-node mesh topology(all nodes are connected to all). When I run the code, even though the neighbours are getting allocated correctly, they all are getting deleted in the middle. So, when I send a packet from any node, they are getting dropped. Can anyone tell me the possible cause? . (I know its more of cldp-oriented question rather than tinyos.

[Tinyos-help] [Tossim] Duplicate messages
Hi, I use a 200 node topology(topology is connected with zero link loss rates) on Tossim. I want to calculate the quality of the network in terms of path stretch and success rate. For that each node will send messages to all other nodes periodically for one cycle. I capture the sent and received packet details onto a file. So, I send 39,800 messages totally. I find that the packet loss in between the nodes are high (approx. 50%) even though the link loss rates are zero. Does this mean that, tossim simulates packet loss due to collisions and interference? Even if it does, would the loss rate be this high? I see a a lot of duplicate receive messages though the sends are unique.

[Tinyos-help] Cannot compile the code in tinyos-2.x
Greetings,
I'm a beginner in tinyos.
Im trying to run a code created in the 1.x days onto tinyos-2.x. When I
tried compiling the unmodified code in 2.x, I'm getting the error as "7:
component Main not found" followed by series of errors attached with this
mail. From the TOSSIM tutorial I learnt that I need python to run the
tossim. So, when I was following the steps as in the tutorial, I couldnt
create a tossim object using "t= Tossim([])" it gave NameError:name Tossim
is not defined.
Can you please tell me what is the actual problem?
Is it purely an upgrade issue? or its two different set of problems?
Awaiting an earlier suitable reply.
Thanks,
Pratibha

Re: [Tinyos-help] [TOSSIM] simulate node leave
Hi,
Yeah, I did try something like that:
while(time){
if (isOn and time > OffTime * t.ticksPerSecond()):
mote(i).turnOff()
isOn = FALSE
t.runNextEvent()
}
But, it is turning off at the end of the simulation only and not when time >
Offtime.
Regards,
Pratibha

[Tinyos-help] maximum packet size
Hi, Is there any limit to the packet size inclusive of all the headers and crc? The CC2420 TEP, says that the max size is 128 bytes according to 802.15.4 spec, but it also says that you can increase the size by changing the TOSH_DATA_LENGTH with a trade-off of potential interferences. Can I assume that excepting the consequences, there is no limit on the packet size?

[Tinyos-help] dsr source code?
Hi, Can anyone tell me if there is any tinyos implementation of dsr (dynamic source routing) available? Regards, Pratibha ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
[Tinyos-help] [Tossim] packet loss model
Hi, Can anyone tell me what is the model used by tossim to simulate packet losses at the physical layer and at the mac layer? For the physical layer we would be giving them the noise model along with the topology, but how the tossim uses these values to model losses?? (The mathematics behind it. I want to calculate the probability of packet loss due to collision and due to physical layer loss) Thanks and Regards, pratibha ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
[Tinyos-help] [PoolC] Returning NULL
Hi,
PoolC get() is returning NULL even though not Pool.empty() and
Pool.size()>0.
I allocate a pointer-to-struct say 'position_t' having three pointers v[3],
typedef position * position_t;
interface Pool;
void New_position()
{ position_t pos;
if(! call Pool.empty()){
atomic{
pos = call edgePool.get();
}}
else
{
dbg_clear("usr","Out of memory - %d\n",call Pool.size());
exit(0);
}
if(pos == NULL) // Becomes TRUE and printing non_zero size
dbg_clear("usr", "Failed allocation -%d\n", call Pool.size());
pos->v[0] = NULL; // SEGMENTATION FAULT OCCURS HERE
pos->v[1] = NULL;
pos->v[2] = NULL;
return pos;
}
this code doesn't cause segmentation fault every time, it is
called. variables in Pool will be constantly allocated and freed. after some
put()s and get()s, this is causing error. Can anyone tell me why?
Regards,
Pratibha

sorry, that was a typo.. im getting and putting in the same pool.

Re: [Tinyos-help] [PoolC] Returning NULL
It is because of the emptyIndex. I was initializing objects with sizes 140,
150 and (index + free) was exceeding 255. for smaller sizes, it is not
causing this error. When i change the size of emptyIndex to uint16_t with
the same 140,150 sizes, it is working fine now. Thank you all :)
