[ns] Segmentation during leach simulation run...
Hi, i m working on the reliability of WSN and trying simulate leach tcl script generated by mannasim script generator tool on ns-2.29 but when i run the script i get the segmentation fault error. also the trace file contains no captured data. i'll be grateful if anyone can help me in this regard.Regards, Najma Ismat

[ns] Error: Meta size 4064 too large (max = 1000) Help Needed!!!!!!
Hi, i m simulate leach tcl script generated by mannasim script generator tool on ns-2.29. when i run a simulation it ends with an error meta size 4064 too large (max=1000). i tried with 100 nodes and 10 nodes but simulation ends with the same error. i've read it at one of the sites that change meta size from 1000 to 4000 in /ns-allinone-2.29/ns-2.29/common/packet.h and then rum make clean and make. when i tried that command it gives gen.o error and make failed. i run install again and than run my leach.tcl script and gives segmentation fault. i revert the changes made and execution of leach tcl script is giving the same error. Please help me in finding the solution to this problem. thanks in advance, - There is 100 data aggregated.Node 98 - Temperature Data 24.674213 - Time 7.115507Common Node 98 - Disseminating data - Time 7.116 - There is 100 data aggregated.Node 99 - Temperature Data 27.275256 - Time 7.115507Common Node 99 - Disseminating data - Time 7.116 - There is 100 data aggregated.Node 100 - Temperature Data 16.863848 - Time 7.115507Common Node 100 - Disseminating data - Time 7.116 - There is 100 data aggregated.Warning!

[ns] leach error.... help needed!!!
Hi,i've made change from char meta[1000] to char meta[2000] in packet.h and sigSize to 225 plus hdr_size=25 (accordinh leach packet size=2000) in leachApp.cc and ran make clean and make in ns-2.29 folder but when i ran the leach tcl script it still gives the same error meta size 4064 too large (max=2000). please guide what else to done to correct this. please urgent help is needed.regards, Najma Ismat

[ns] Mobility error
hi,i m trying to simulate wsn with mobility and i have used bonnmotion for
adding mobility in wsn. the problem is when i run the simulation script it
gives the following error. what i can get from the following error is that
there is some problem in reading bonnmotion movement patern file. i have used
the movement pattern file the way we use it for manet like:
set val(t) "S1.ns_movements"and calling that file after the creation of
nodes

Hi,I want to change the transmission range of sensor node from 100m to 250m and and i have read that for changing transmission range i should change the RXThreshold. In my tcl script which is generated using tcl script generator i m confused with some parameters for the calculation of RXThreshold. Phy/WirelessPhy set Pt_ 0.281838Phy/WirelessPhy set freq_ 2.4e09Phy/WirelessPhy set L_ 1.0 Phy/WirelessPhy set lambda_ 0.125 Phy/WirelessPhy set RXThresh_ [TwoRay 0.281838 [$antenna set Gt_] [$antenna set Gr_] 0.8 0.8 1.0 $range 0.125] Gr_and Gt_ =1.0range=100 Can anyone guide how to interpret these values in pink bold color and calculate RXThreshold value?

[ns] Node Position
Hi,I am want to implement grid topology in mobile wsn and before the start of specific protocol operation i want to identify nodes in a grid so that routing protocol should only used nodes that exists in that grid. Nodes initial position and movement pattern is stored and taken from mobility pattern file. Can anyone guide how to achieve this also how should i run individual routing solution in every grid. I'll be extremely grateful if anyone can guide.Regards,Najma Ismat
[ns] Accessing nodes
Hi,I want to control cluster-head selection process of leach where only some specific node's should be selected as Cluster-head but whenever protocol run, it randomly picks node for the possible contender of being a cluster-head.Please guide how to access all nodes before the start of a round. I m using ns-2 mannasim, and nodes are mobile and their movement is provided in mobility pattern file. Regards,Najma
[ns] Accessing node coordinates
Hi, I m simulating Leach protocol with mobility and I want to print all mobile sensor nodes coordianates at the start of every round. I have been able to access node coordinates with the help of a command, but whenever I tried that at the start of the round I can only access nodes that are contending for being CH. Please guide how to get coordinates of all nodes at the start of every round? Regards, Najma Sent from my iPad
