摘　　要：针对移动Ad Hoc网络中,自私节点会影响网络性能,甚至导致网络瘫痪等问题,提出新的用于Ad Hoc网络检测自私节点的信誉机制。该机制采用一种新的直接监测技术评估网络中节点的信誉,允许为其他节点转发数据或路由控制信息而消耗自身能量的节点进行网络通信,而行为自私的节点会被监测或隔离。仿真结果表明,利用该机制能较为准确检测到自私节点,提高网络吞吐量。A reputation mechanism is proposed for the detection and isolation of selfish nodes in Ad Hoc networks,which based on what caused by the case that selfish nodes will affect the performance of the net- work, and even lead to paralysis of the network. The mechanism uses a new direct monitoring technique to evaluate the reputation of nodes in the network. The mechanism allows for other nodes to forward data or routing control and consume their own energy nodes for network communication, and the selfish behavior of the node will be monitored or isolated. Simulation results show that, this mechanism can accurately de- tect the selfish nodes, and makes the network throughout rate return to normal.
