Trust Opportunistic Routing Protocol in Multi-hop Wireless Networks
The opportunistic routing paradigm is a new avenue for designing routing protocols in multi-hop wireless networks. Unlike traditional wireless routing protocols which use a single predetermining path, opportunistic routing explicitly takes advantage of the broadcast nature of wireless communications by using a set of relay nodes to opportunistically perform packet forwarding. Network security is also a hot research topic on routing. However, combining above two ideas to devise an effective routing is none. This paper aims at giving a new solution to solve it by defining a new metric called E2TX(trustworthiness and ETX). Using this metric, we also consider the two key issues for a new routing protocol called TOR: candidate selection and prioritization of relays in classical opportunistic routing. Through extensive simulations by NS2, we demonstrate that TOR outperforms class routing:ExOR, in terms of packet delivery ratio, delay and routing overhead.
