Abstract

Broadcasting is an indispensable operation to provide control or routing functionalities for multi-hop mobile ad-hoc networks (MANETs). In MANET, since a packet relayed by any node can reach all its neighbor nodes, broadcasting by traditional flooding is inefficient and results in severe redundancies, contentions, and collisions. In this paper, we analyze the deficiencies of recent published scheme and present a novel broadcasting approach, PIB, using the predecessor node information to efficiently reduce the number of retransmitting nodes and to solve the broadcast storm problem in MANET. The most important feature of the proposed algorithm is that it does not require any extra communication overhead other than the exchange of 1-hop HELLO message, while maintaining the high deliverability. Comprehensive simulations are performed to show that the proposed scheme significantly reduces the redundant transmissions in 1HI and pure flooding; accordingly it alleviates the collisions in networks.
