Energy performance of zoning techniques for broadcast processing with reduced redundancy in MANETS

Many routing protocols have been proposed in mobile ad hoc and sensor networks in order to optimize their performances. The geographic forwarding rules (GFR) fall within the category of the techniques that reduce the routing overhead. Several zoning techniques have been proposed for the GFR, but only one method have been studied. Performances of this technique have been presented focusing on metrics like throughput, delay and routing overhead. However, the GFR affect also the residual energy of nodes since they decrease the number of retransmissions of broadcast messages. In this paper, we study other zoning techniques focusing on the power consumption of the GFR. We present a comparison analysis of energy usage of different zoning techniques with two, four and eight zones. We evaluate how the zoning method affects the energy consumption in mobile devices.
