Cross Layer Design for Rate Selection and Link Failure Prediction in MANETS
Recently, in an effort to improve the performance of wireless networks, there has been increased interest in protocols that rely on interactions between different layers. The nature of temporary links and the mobility of the nodes together with wireless transmission effect on attenuation, interference, and multipath propagation, raise some inherent issues of mobile ad hoc networks. Cross-layer design allows them to make better use of network resources by optimizing across the boundaries of traditional network layers. It is based on information exchange and joint optimization over two or more layers.
