NEIGHBOUR COVERAGE BASED PROBABILISTIC REBROADCAST REDUCTION OF ROUTING OVERHEAD AND CROSS TALK AVOIDANCE IN MANETS

In this approach if there exists any cross talk while communicating two parties, the connection will be terminated as soon as the crosstalk has been identified. It also improved crosstalk avoidance by either re-routing the communication or by terminating it with the help of packet transmissions and overhead. In order to limiting the number of rebroadcasts can effectively optimize the broadcasting, a neighbor coverage-based probabilistic rebroadcast (NCPR) protocol, in order to effectively exploit the neighbor coverage knowledge. A novel rebroadcast delay to determine the rebroadcast order, and then obtain a more accurate additional coverage ratio and by keeping the network connectivity and reduce the redundant retransmissions, a metric named connectivity factor to determine how many neighbors should receive the route request (RREQ) packet. By combining the additional coverage ratio and the connectivity factor, introduce a rebroadcast probability, which can be used to reduce the number of rebroadcasts of the RREQ packet to improve the routing performance.
