Abstract

An enhanced fisheye state routing using cross-layer optimization was proposed. CO-FSR synthetically considers the state of MAC and network layer synthetically, adopts cross-layer technology to balance network traffic while supporting QoS better and achieving better network performance. In CO-FSR, the node that has worse traffic load state will not be selected to forward data packets even though it is on the shortest (that is, the number of hops is the smallest) path between source-destination pair. Simulation results shows that CO-FSR can decrease average end-to-end delay and increase throughput especially when the network has more offered load. CO-FSR inherits the merit of FSR such as simple, efficient and scalable etc while taking into account cross-layer optimization. Thus CO-FSR proves to be a more efficient solution to the routing problem in large mobile ad hoc networks.
