Mitigating selfishness in mobile ad-hoc networks using virtual mobility

With recent performance increase in the area of wireless mobile communications, mobile ad-hoc networks are playing a wide spread usage in the areas of military and other applications. Cooperation among the nodes in ad-hoc networks is an important issue for communication to be possible. But some nodes do not cooperate in communication and saves their energy. These nodes are called as selfish nodes. In the literature there are many methods which deal with the selfish behaviour of the nodes. This paper proposes an approach based on incentive mechanism in a different manner. Here nodes are "made" selfish for some time to encourage nodes to cooperate in the communication. This reduces selfish behaviour. Thus this approach is called as cut diamond with diamond.
