Subject: problem regarding random waypoint model implementation
To: [email protected]
hello ns-2 users
my name is davesh som and i am having problem with my aodv
ns-2 implementation.My code works fine if i am using 2rayground model but i
want to perform the simulation using RANDOM WAYPOINT MODEL.I am new to the
ns-2 so please can anyone guide me that how should i do that with the same
code i mention in this mail.I attach my code here please go through it.
Thanks in advance.
