摘要 针对移动Ad hoc网络中节点自私性问题,提出了一种基于节点状态的节点协作激励机制NSIM。利用虚拟货币来激励中间节点转发数据,节点的报价是综合考虑节点状态计算得出的,避免资源紧张的节点参与数据转发;在节点中引入安全模块和加密机制,防止节点篡改其他节点的报价和非法增加虚拟货币。仿真实验表明,NSIM机制减小了时延,提高了分组投递率。 Aiming at the selfishness of nodes in mobile Ad hoc network , a node status based incentive mechanism ( NSIM ) is proposed in this paper . Virtual money is used to motivate the nodes forwarding data . The node designs prices taking into account the nodes′ status to avoid nodes with limited resources participating in forwarding data . A safety module encryption mechanism is imported into the mechanism to prevent some nodes from tampering other nodes′ quoted price and illegitimately increasing its own virtual money . Simulation results show that NSIM mechanism can decrease the delivery delay and increase the delivery ratio .
