Cross-layer based routing protocol for Wireless Sensor Networks using a fuzzy logic module

Communication protocols have been designed according to a layered stack architecture, but with the evolution of networks, this layered stack system cannot meet the wireless network requirements. In sensor networks, and specifically the routing issue, given the need to conserve sensor energy and maximize application performance, cooperation between several layers in the protocol stack is needed. This can be reached in a cross-layer architecture. Cross-layer design allows protocols belonging to different layers to cooperate and share network status information; this will ensure that the best route is chosen by taking into consideration energy consumption and performance requirements. This paper presents a routing protocol for Wireless sensor networks using Cross-layer approach for energy optimization and lifetime raise.
