Distributed Trust Establishment in MANETs’ Swarm Intelligence

We present some properties of trust establishment in mobile, ad-hoc networks and illustrate how they differ from those of trust establishment in the Internet. We present a framework for trust establishment in mobile ad-hoc networks and argue that peer-to-peer networks are especially suitable to solve the problems of generation, distribution, and discovery of trust evidence in mobile ad-hoc networks. We develop a new scheme based on swarm intelligence and demonstrate its advantages over the peer to peer scheme. We evaluate our approach through simulation with NS-2.
