Cross-layer design for wireless mesh network and its application

According to the basic principles of cross-layer design for wireless mesh network,the functions of major modules and the various factors to be taken into account in the system are analyzed.An implementation scheme of cross-layer design is proposed,in which the efficient method for network state information exchange and advanced routing algorithm are employed. With the method a reasonable transmission route can be determined by the factors including current link states,congestion and energy of the network. A example of the scheme application in a high voltage transmission monitoring system is presented. The simulation and experiment show that the scheme has good performance in robustness,throughput and delay.
