Abstract :
The performance of GeRaF is recently evaluated on Rayleigh fading channels. However, in practical systems, line-of-sight paths might exist between sensor nodes. We evaluate the performance of GeRaF under a more realistic channel model. Specifically, multihop performance of GeRaF is studied under lognormal-shadowed Rician fading channels in this paper. Both analytical and simulation results are presented and yield further insight to the performance of GeRaF
