[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 cont

[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.

[ns] how to change the transmission range of a node???

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 RXThresh

[ns] Energy Model

Hi,I want to modify the energy model of sensor node. I m using ns-2.29 mannasim for sensor network simulation. I want to modify the energy model for sensor node and have read in mannasim class manual that the battery class of sensor node extends Energy-model class which means all fields are inh

[ns] Ns-2 make error

Hi, I m working on the energy model of leach protocol, and for that using Ns-2.29 with mannasim. I have added few lines in battery.cc and battery.h ( which is used for sensor nodes), and run make command, my code compiles perfectly without any error, then I commented the changes made and run m

[ns] GaussMarkov mobility model
