An Efficient Cross-Layer Based Flooding Algorithm with Retransmission Node Selection for Wireless Sensor Networks

In this paper, we propose a flooding algorithm with retransmission node selection (FARNS) for wireless sensor networks. It is an efficient cross-layer based flooding technique to solve a broadcast storm problem that is produced by simple flooding of nodes in wireless sensor networks. FARNS can decrease waste of unnecessary energy by controlling retransmission action of whole network nodes by deciding retransmission candidate nodes that are selected by identifier information of neighbor nodes in MAC and distance with neighborhood nodes through received signal strength information in PHY. In simulation results show that FARNS has excellent performance than the other flooding schemes in terms of broadcast forwarding ratio, broadcast delivery ratio, and the number of redundancy packets and overhead.
