A Bargaining-Based Approach for Incentive-Compatible Message Forwarding in Opportunistic Networks
Opportunistic networking is an important technique to enable users to communicate in an environment where contemporaneous end-to-end paths are unavailable or unstable. To support end-to-end messaging in opportunistic networks, a number of probabilistic routing protocols have been proposed. However, when nodes are selfish, they may not have incentives to participate in probabilistic routing, and the system performance will degrade significantly. In this paper, the authors present a novel incentive scheme for probabilistic routing that stimulates selfish nodes to participate. They not only rigorously prove the properties of their schemes, but also extensively evaluate their schemes using GloMoSim.
