Cross-layer design-based Multipath Routing Protocol (CMRP) for mobile ad hoc networks

Abstract

Abstract This paper proposes a Cross-layer design-based Multipath Routing Protocol (CMRP) for mobile ad hoc networks, using the node energy signal from the physical layer. The purpose is to optimize routing decisions and path quality. The nodes’ mobility behavior is predicted using a notion of “Signal Fading Degree, SFD”. Especially, in the combination of the IEEE 802.11e standard at the MAC layer, we determine that the IEEE 802.11e makes a significant contribution to the performance improvement of CMRP. Performance evaluation of AODV in legacy 802.11 and CMRP in IEEE 802.11e shows that, as a function of the speed of node mobility, a tremendous reduction was achieved, in metrics such as the average end-to-end delay, route overhead, route discovery frequency, normalized routing load – almost more than 80%, 40%, 40%, and 40%. In the case of a varying number of sessions, the reduction for route discovery frequency and normalized routing load is up to 70% and 80%.
