On Physical Layer-Oriented Routing With Power Control in Ad Hoc Wireless Networks

Routing in ad hoc wireless networks does not simply consist in finding a route with shortest length (as in wired networks with virtually error-free communication links), but it requires the creation of a stable and good quality communication route to avoid any unnecessary packet loss. In this paper, the authors discuss physical layer-oriented routing in ad hoc wireless networks, and they analyze the potential advantages of combining the use of Power Control (PC) with the chosen routing strategy. More precisely, they propose a Modified Ad hoc On-demand Distance Vector (MAODV) routing protocol, with and without PC, derived from the AODV-routing protocol by considering the bit error rate at the end of a multi-hop path as the metric to be minimised for route selection.
