I want to modify AODV inorder to get reduced routing overhead. Please help me Following are the changes of source code I want to modify.
Only when the time elapsed from the last broadcasting packet (RREQ, RERR, or some other broadcasting packets) is greater than the value of HelloInterval, the node needs to send a Hello packet. The value of HelloInterval is equal to that of the original AODV In order to reduce the overhead of neighbor list in the RREQ packet, each node needs to monitor the variation of its neighbor table and maintain a cache of the neighbor list in the received RREQ packet. We modify the RREQ header of AODV, and add a fixed field num_neighbors which represents the size of neighbor list in the RREQ packet and following the num_neighbors is the dynamic neighbor list.
