A trust-based opportunistic routing algorithm in Ad hoc network

By making the best of the wireless channel´s broadcasting property, opportunistic routing can greatly improve the performance of wireless multi-hop networks. Traditional routing security mechanism is no longer suitable for the design of routing protocol in Ad hoc network. So this thesis introduces trust, i.e. the concept of security and credibility into opportunistic routing, and put forward an opportunistic routing algorithm based on trust. According to the simulation result, compared with ExOR algorithm of traditional opportunistic routing, TOR algorithm can prevent attacks of malicious node, improve the robustness of network and has an advantage in aspects such as handling capacity and end-to-end time delay.
