An anti-jamming routing selection criteria based on the cross-layer constraints of channel state information for MANETs

MANETs are a high adaptable solution to military and emergency services scenarios, where the schemes are of rapid deployment and maintaining connectivity even in complex radio propagation and jamming environments. To apply it in the tactical or emergency services environment, it should provide assurance that the packet delivery is reliable despite of local congestion and jamming. Considering link reliability and path stability can greatly improve the anti-jamming capabilities of protocols. A novel reliable anti-jamming routing policy based on cross-layered neighbor dependency is presented in this paper. The Channel State Information (CSI) refers to channel properties of a link and describes how a signal propagates from the transmitter to the receiver and represents the combined effect of scattering, fading and power decay with distance. According to the neighbor dependency evaluated by CSI, how to select a neighboring node as the next hop node will greatly degrade the transmission reliability. Finally, The simulation results show that the reliable routing protocol based on neighbor dependency (RPBND) protocol our proposed significantly outperform better transmission reliability than the classical AODV algorithm and the improved AODV based on link Cost (CAODV) algorithm.
