A flooding protocol for MANETs with self-pruning and prioritized retransmissions

In this paper, we introduce a highly efficient flooding protocol for MANETs using only one-hop hello messages. By simulation, we show that the protocol has a performance close to flooding protocols that use two-hop hello messages. Further, the protocol performs very good even when the node mobility increases. The only "cost" this protocol must pay is an increased end-to-end delay. However, with some clever cross-layer optimization, this delay can be reduced to become comparable with other flooding protocols. Further, the overhead generated for flooding a packet by this protocol is lower than other protocols, if one-hop hello messages are already provided.
