Hi all
I'm having a strange problem when I send a unicast packet in ns-2 (I use the
IEEE 802.15.4 module).
I've created a new packet type, and when the IP-destination field
(HDR_IP->daddr()) is set to broadcast, the packet is received by the nodes
correctly. However, when I set a specific ad
Hi all
I am working with the IEEE 802.15.4 ns-2 implementation. I added a new packet
type and I have problems when I try to send it.
I define the packet, which size of payload is 8 bytes (ch->size() = 8 +
IP_HEADER_LEN). Then, I populate the HDR_CMN fields like this:
__
Hi again
I am sorry but I found the problem. It was my mistake. The thing is that I am
using an aodv queue and the packet was being dropped because of timeout.
Thanks!

Hi all
I have the following problem. I am working with the IEEE 802.15.4 Zheng's
implementation in ns-2. In the routing layer I send a cbr packet where the
HDR_CMN(p)->next_hop_ is set to a specific node address. However, at MAC layer,
some cbr packets are not sent to that node but to another.
Hi all
I have a problem with the MCPS_DATA_request primitive in the IEEE 802.15.4 ns-2
implementation. I build a new packet and send it peridically using this
primitive (broadcast transmission). The thing is that this error does not
always happen because I can send the packet, and it is receiv
Hi all
I found the
solution: http://old.nabble.com/Error-while-including-wireless-phy.h-td21661874.html.
I think it is an important BUG in ns-2.
Thanks for the help.

hat if I don't include "p802_15_4mac.h", the problem dissapears,
but I can't use mac functions( e.g. MCPS_DATA_request()).
I searched this same problem on the Web (google and ns2 help) and I found
similar problems (http://www.mail-archive.com/ns-users@isi.edu/msg06434.html),
but the solution
It is strange that I hadn'n found anything about mannasim until now. Thanks,
I'll try to use it.

I am at the point of simulating my work and get final results so I have to do a

I've

what to do. For example, I need to put a for
Hi,
at the end I did it. The problem was that I was'n using the correct function to
pass directly the packet to the routing layer and as you say, the packet was
being erased.
Thanks a lot.

Hi all
Sometimes, I have to cancel a packet transmission at MAC layer and in this
case,
I want to send the packet to the routing layer again and store it in a queue to
sending it later. I've been trying to make that at mcps_data_request method of
p802_15_4mac.cc, just at the moment when the n

I'm not sure but can't you simply say something like this on the receivers
side?

Hi
I had a lot of problems with the instalation of ns 2.28 too. You should follow
the next steps:
1) Decompress ns-allinone 2.28
tar xvzf ns-allinone-2.28.tar.gz
2) Patch nam: you need the patch file (I attach it)
cp nam-1.11.patc

Hi all
I'm working with IEEE 802.15.4 and NS2 2.28. I'd like to know what is the
portion of code that allows to put (simulate) on/off the node in sleep mode. I
want to do that at some time.

d of my routing protocol I may put the code to enque and deque

(Another thing, I forgot to say that I'm using IEEE 802.15.4)
Please, I need help with that, I know a lot of things, but I'm not what to do!!

I have to questions:
How can I control the transmission of packets? I want all nodes transmit their

And If I don't want to use CSMA/CA, what I have to do?
