Channel-aware routing protocol for wireless Ad-Hoc networks: generalized multiple-route path selection diversity
Jia Liu, A. Annamalai · 2006
Recently, (2) discussed the implementation aspects and performance evaluation of multiple path route selection (MRPS) route strategy for a specific m-path n-hop network topol- ogy over Rayleigh fading channel. MRPS is attractive because it is scalable and less sensitive to the size of the network. In this paper, we extend the analysis in (2), (3), (5) in several fronts: (i) we develop a recursive algorithm to compute the end-to-end outage probability (EOP) for MRPS in a more general network topology; (ii) our analysis is not restricted to Rayleigh fading but is applicable to a wide range of fading distributions including Rice, Nakagami-m, Nakagami-Hoyt, and Weibull fading channel models; (iii) we propose a new routing protocol MRPS-T based on selecting T best paths for forwarding the packet to the next hop. This algorithm is also scalable and can yield performance better than MPRS in terms of EOP metric. MRPS-T also admits MRPS for the special case of T =1 .
