Reputation-Based Routing in Hybrid Ad Hoc Networks

摘要

Within Ad hoc networks, IP connectivity is achieved with the help of multi-hop routing; nodes are supposed to cooperate and act as routers for the benefit of the others. However, this cooperation-based paradigm has limitations, because nodes do not always make their resources available, properly. We propose a reputation-based routing protocol, called MOOR, for application to hybrid Ad hoc networks. MOOR aims at improving the reliability of communications between Ad hoc nodes and the gateway to an infrastructure-based network. We present an application-motivated performance analysis of our protocol MOOR, which allows to quantify the benefit in terms of radio network coverage increase. The impact of non-cooperative nodes on a MOOR protected network remains rather low, even for nodes located 5 hops away from the gateway.
