<H2>Abstract</H2> 

  Technological advances are leveraging the widespread deployment of
  mobile ad hoc networks. An interesting characteristic of ad hoc
  networks is their self-organization and their dependence of the
  behavior of individual nodes. Until recently, most research on ad
  hoc networks has assumed that all nodes were cooperative. This
  assumption is no longer valid in spontaneous networks formed by
  individuals with diverse goals and interests. In such
  environment, the presence of selfish nodes may degrade significantly
  the performance of the ad hoc network.  This paper proposes a novel
  algorithm that aims to discourage selfish behavior in mobile ad hoc
  networks.
