Routing with Interference Reduction and Opportunistic Estimation Against Multiple Jammers in MANETs with Energy Harvesting

The routing for a wireless network in multi-hop scenario can be actively attacked by jammers which severely deteriorate the performance of the network. One of the important examples is a mobile ad hoc network in which the legitimate nodes move and harvest energy from the radio environment. The challenges are that the jammers continuously vary their jamming signals, transmit with a power which is much larger than that of the legitimate nodes, and all their instantaneous channel gains are unknown. We propose two novel schemes of opportunistic combination and removal of the jamming signals from the dominant jammer by using the estimates of the channel ratios. Simulation results show that the proposed schemes are better than a conventional scheme in terms of the total delivery time, number of hops, and successful delivery ratio.
