[ns] Problem with running 802.15.4

Hi, Really need help. I'm performing analysis on the performance of 802.15.4 and aftering runing ns2 (AODV,cbr), i got this error [wpan/p802_15_4phy.cc::PD_DATA_request][8470.807910](node 4) Invalid PSDU/MPDU length: type = AODV, src = 4, dst = -1, uid = 0, mac_uid = 406423, size = 135. I

[ns] Generation of traffic for 802.15.4 peer to peer

Hi, Was wondering if anyone could advice me on how to generate the traffic (connection pattern) for a peer to peer network. Basically, i need to send data between nodes that are at the circumference and also from the circumference nodes to the PAN coordinator. I desperately need to get

[ns] Traffic generation to analyse performance of 802.15.4

Hi, Could anyone advice me how to generate the traffic for analysis. Basically, i've generated a mobility file based on ocean movement and it last for 24hrs. Not sure what and how traffic pattern can be generated. Appreciate for any advice, thanks. Regards, Kwang

[ns] How to use calcdest

Hi, Does anyone knows how to use the "calcdest" command to calculate the shortest hop for the god object. I've tried it on my movement file and the return message is ['setdest's must be in anti-chronological order in input file! failed on node 0]. Would appreciate for some advice please.

[ns] Node movement

Hi, I've been trying to create a movement file to evaluate the performamce of IEEE 802.15.4. Can anyone advice me on how to create manual node movement. I've the X,Y position of nodes and the next positions at a 10 mins interval. Appreciate if anyone could advice. Thanks Kwang __

Re: [ns] R: How to generate ocean node movement for wireless scenarios

Hi Marco, Thanks for yur advice. Is there a way to define node movements through an array of data? The concern is that i'm trying to create 100 nodes moving in a time frame of 24 hrs and there are lots of data. Regards, Kwang Yong >From: Marco Fiore <[EMAIL PROTECTED]> >Reply-To: Marco Fiore

[ns] How to generate ocean node movement for wireless scenarios

Hi all, i'm trying to generate a scenario for node movement in an ocean environment. I've got a sets of data that is assocated with time, Longitude, Latitude, velocity ( U (cm/s) & V (cm/s)). Can anyone advice me how this can be done? Thanks, Kwang Yong
