Modified Neighbour Coverage Based Probabilistic Rebroadcast in MANET

Roopali Garg, Guneet Kaur

Mobile ad hoc networks involve several mobile nodes which are self configuring. Due to rapid movement of the nodes link breakages occur, which lead to the rebroadcast of a request. To optimize the broadcasting, the number of rebroadcasts should be limited. To reduce the routing overhead we describe a method in which neighbour knowledge and rebroadcast probability are used for rebroadcasting a request. In this paper we propose a scheme to enhance the existing neighborhood coverage based probabilistic rebroadcast using the technique of particle swarm optimization.
