A Novel Charging and Accounting Scheme in Mobile Ad-Hoc Networks

摘要

Because of the lack of infrastructure in mobile ad hoc networks (MANETs), their proper functioning mustrely on co-operations among mobile nodes. However, mobile nodes tend to save their own resources andmay be reluctant to forward packets for other nodes. One approach to encourage co-operations amongnodes is to reward nodes that forward data for others. Such an incentive-based scheme requires a chargingand accounting framework to control and manage rewards and fines (collected from users committinginfractions). In this paper, we propose a novel charging and accounting scheme for MANETs. We present adetailed description of the proposed scheme and demonstrate its effectiveness via formal proofs andsimulation results [15]. We develop a theoretical game model that offers advice to network administratorsabout the allocation of resources for monitoring mobile nodes. The solution provides the optimalmonitoring probability, which discourages nodes from cheating because the gain would be compensated bythe penalty.
