摘要

针对移动自组网中自私节点出于节省资源而表现出不合作行为及丢弃待转发数据等问题

提出了一种面向信誉的自组网节点合作(CMC)方法

且第一次引入了共同邻居监听技术.看门狗在对下一跳转发节点进行监听的同时

可对周围不相关的数据流进行监听

从而加快了系统对不合作节点的检测速度.在路由发现过程中

CMC对路由控制消息进行了过滤

丢弃含有不合作节点的路由请求包和路由应答包

使源节点发现的路由能尽量绕过不合作节点.在ns-2下的仿真结果表明

当网络中存在10%～60%的不合作节点时

CMC能够使合作节点的吞吐率提高10%～40%.

Abstract

In mobile ad hoc networks

selfish nodes show non-cooperative behaviors due to discarding packets to save their resources(such as energy)

which will seriously affect the network performance. A new cooperation enforcement scheme called CMC is proposed to mitigate this problem. In the CMC

the common neighbor monitoring technique is introduced to help the watchdog monitor all packets transmitting around it so that the system can detect the non-cooperative nodes more quickly. In the routing discovery phase

the route request packets and the route reply packets that contain non-cooperative nodes are dropped by CMC

so that the probability that a well-behaved node uses a bad route for data transmission is reduced. The ns-2 simulation results show that the CMC can improve the throughput of well-behaved nodes by 10%-40% in the presence of 10%-60% non-cooperative nodes.
