Abstract
Many existing studies just considered that nodes in a Mobile Ad Hoc NETwork (MANET) would fully cooperate to forward packets for one another. However, this assumption does not hold in many scenarios. The node selfishness in relay cooperation will certainly influence the overall performance of routing in MANETs. In this work, we investigate the energy-aware routing problem in MANETs with nodes' selfishness. We model the situation of node cooperation in energy-aware routing by using game theory. We consider the competitive and cooperative relationship between the nodes to formulate the game for MANETs. An incentive mechanism is given in order to encourage forwarding cooperation during energy-aware routing. Nodes are encouraged to forward more data packets for others in order to acquire more services from others. We also carry out a simulation for the proposed method and perform detailed analysis in this work. From the results of the simulation, we argue that it's possible to find out a suitable configuration for a MANET to support more efficient energy-aware routing through our method.
