Cross Layering in Wireless Multi-hop Networks

Recently in an effort to improve the performance of Wireless Multi-hop Networks in the face of random variations of physical channel and network status, there has been a trend towards employing interactions between different layers in the protocol stack. Using this approach called cross layering, resource allocation and decisions will be done with a more global view of the network and can reduce instabilities of wireless network. In this paper we propose a new approach in cross layering which exploits information of MAC layer passed to the routing agent which tries to choose the best quality path with least congestion towards the final destination. We show that by using the proposed method better performance in terms of delay and throughput is achievable.
