Resource-Exchange Based Cooperation Stimulating Mechanism for Wireless Ad Hoc Networks

Free registration required

Executive Summary

In this paper, a multi-user cooperative game is proposed to stimulate selfish user nodes to participate in cooperative relaying in wireless ad hoc networks. Without using the traditional reputation-mechanisms or pricing-mechanisms, the authors resort to the resource-exchange mechanism by assuming a source node could reward the relaying nodes by, in return, forwarding data that are originated from these relaying nodes. Then the cooperation stimulating problem can be formulated as a multi-player cooperative bargaining game. They prove that there exists a unique Nash Bargaining Solution (NBS) of the game and propose a fast Particle Swarm Optimizer (PSO) algorithm to solve the NBS.
