A Reputation-based Service Differentiated Incentive Mechanism for MANETs

摘要: 为了有效解决移动自组网节点在自觉提供服务方面的自私行为问题，该文提出了一种基于信誉的区分服务激励机制。该机制通过建立一种分簇全局信誉模型，并结合节点能力将服务与信誉进行等级关联，提供差异化服务；信誉级别越高的节点可以使用级别越高的服务，使用服务或者故意不提供服务会减少节点的信誉，节点需要积极提供可靠服务提高信誉才能保障服务的使用。仿真结果表明所提机制能有效抵制节点的自私行为，激励节点积极提供可靠服务。Abstract: A Reputation-based Service Differentiated Incentive (RSDI) mechanism is proposed in this paper to solve the selfish behavior of nodes during consciously supporting services efficiently for Mobile Ad-hoc NETworks (MANETs). With a clustering global reputation model and associating services with reputation using grades, RSDI provides differentiated services based on reputation; The nodes which have higher reputation level can consume higher level services, consuming services or refusing to provide services intentionally will reduce nodes reputation, nodes need positively provide trustworthy services to increase their reputation in order to ensure consuming services. Simulations show that RSDI can resist the selfish behavior of nodes, and motivate nodes to positively provide trustworthy services effectively.
