A Guide to Trust in Mobile Ad Hoc Networks
Source: University of London
In this paper, the authors examine issues of trust and reputation in Mobile Ad hoc Networks. They look at a number of the trust and reputation models that have been proposed and they highlight open problems in this area. A Mobile Ad hoc NETwork (MANET), as described by the Internet Engineering Task Force (IETF) MANET working group, is a (temporary or permanent) autonomous network comprised of free roaming nodes (wireless communication devices). Nodes within these networks are typically ascribed the following characteristics: nodes move arbitrarily resulting in a dynamic network topology; communication links between nodes may be bandwidth-constrained; messages are typically routed in a multi-hop fashion; nodes may be powered by an exhaustable energy source and nodes may have limited physical security.
