Energy-efficient forwarding for ad hoc and sensor networks in the presence of fading
Michele Zorzi, Ramesh R. Rao · 2004
In this paper we study the multihop performance of two energy efficient forwarding schemes (GeRaF and GAF) in a Rayleigh fading propagation scenario. Specifically, we evaluate the number of hops which are necessary to reach a destination at distance D, as a function of the density of available relay nodes. Analytical and simulation results show that GeRaF significantly outperforms GAF from the multihop point of view. GeRaF's energy/latency performance is also found to be very robust with respect to propagation impairments.
