Secure and Reliable Routing Protocols for Heterogeneous Multihop Wireless Networks - 2015
In this paper, we tend to propose E-STAR for establishing stable and reliable routes in heterogeneous multihop wireless networks. E-STAR combines payment and trust systems with a trust-based and energy-aware routing protocol. The payment system rewards the nodes that relay others' packets and charges those 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 making routing selections. We tend to develop 2 routing protocols to direct traffic through those highly-trusted nodes having sufficient energy to minimize the probability of breaking the route. By this means, E-STAR will stimulate the nodes not only to relay packets, but additionally to keep up route stability and report correct battery energy capability. This is as a result of any loss of trust will 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 will secure the payment and trust calculation without false accusations. Simulation results demonstrate that our routing protocols will improve the packet delivery ratio and route stability.
