Secure and Reliable Routing Protocols for Heterogeneous Multihop Wireless Networks - 2015
In this paper, we propose E-STAR for establishing stable and reliable routes in heterogeneous multihop wireless networks. E-STAR combines payment and trust systems with a trust-primarily based and energy-aware routing protocol. The payment system rewards the nodes that relay others' packets and charges people who send packets. The trust system evaluates the nodes' competence and reliability in relaying packets in terms of multi-dimensional trust values. The trust values are hooked up to the nodes' public-key certificates to be employed in creating routing choices. We develop two routing protocols to direct traffic through those highly-trusted nodes having sufficient energy to minimize the likelihood of breaking the route. By this manner, E-STAR will stimulate the nodes not solely to relay packets, but also to maintain route stability and report correct battery energy capability. This is because any loss of trust can result in loss of future earnings. Moreover, for the efficient implementation of the trust system, the trust values are computed by processing the payment receipts. Analytical results demonstrate that E-STAR can secure the payment and trust calculation while not false accusations. Simulation results demonstrate that our routing protocols can improve the packet delivery ratio and route stability.
