Abstract

Mobile Ad Hoc networks have become increasingly popular in the recent years. Multi-devices cooperating and sharing services is critical to realizing various mobile business applications. However, because mobile nodes are usually constrained by limited resources such as energy, bandwidth, computational power, storage and so on, some nodes may be a unwilling to share the services. Under these conditions we present in this paper a novel trust and reputation model, called NSOICRep, based on an incentive compatible clustering global reputation model aiming at providing trust and reputation in MANETs. Simulations show that NSOICRep can resist the selfish behavior of nodes, and motivate nodes positively share trustworthy services effectively.
