A Cross-Layer Efficient Routing Protocol for Ad hoc Networks

According to the ineffective route repair and high routing overheads of classic AODV, a novel cross-layer efficient routing protocol (CLERP) is presented in this paper. CLERP adopts cross-layer design to establish backup route to reduce the packet losses when link breaks occur. To decrease the unnecessary overhead of hello packets, adaptive links connectivity is employed, which uses adjusting rate of sending hello packets. The simulation results demonstrate that CLERP improves the performance of route discovery frequency, end-to-end delay, packet delivery fraction and routing load compared to AODV.
