Abstract—Most of the recent performance studies in MANETs (Mobile Ad Hoc Networks), consider the effects of multiple layer interactions. These interactions allow layers to exchange state information in order to obtain performance gains. For instance, the routing layer may use the channel state information such as interference and noise in the route discovery process, in order to dynamically select the most stable routes. In this paper, we present a behavior comparison of the routing protocols based on cross-layer approach among physical and network layers. The first protocol is a reactive protocol Ad Hoc On- demand Distance Vector (AODV), the second one is a proactive protocol Optimized Link State Routing (OLSR). Both of them are based on Signal to Interference and Noise Ratio (SINR) metric in their route discovery process. The behavior comparison of the routing protocols is implemented using NS2 simulator with mobile nodes in a shadowing environment qualified as an environment with important variations in the received signal power. Simulation results, using NS2, show that AODV based on SINR metric maximizes the packet delivery ratio and minimizes the overhead cost compared to OLSR based on SINR metric.
