hello to all,
@clederson - my thesis is on "detection and isolation of selfish nodes in
mobile ad hoc network."
if from a total of 50 nodes, let's say 10 nodes energy level reach to 0,
then their simulation should stop so that i can say i have isolated them
from the network. this is exactly i want..
how can i use node_off() function in mobilenode.cc file to do this or should
i use node_on=false as suggested by hemant??
plz reply..
