摘要:
移动自组网是一种特殊的对等式网络,由于拓扑动态变化、无线信道完全开放、没有固定基础设施等特性,易遭受各种攻击,因此移动自组网的安全性显得尤其重要。在分析现有安全路由协议的基础上,设计了一种由节点直接声誉值和间接声誉值组成的声誉评价机制,对于间接声誉值更注重于由近期的交互所获得的声誉值。并在此基础上提出了安全路由协议SR-DSR,选择路径声誉值与路径长度比值最大的路由来发送数据包,提高了数据包传输的可靠度。通过仿真实验表明,在网络遭受恶意节点攻击时,SR-DSR比DSR在包到达率和网络吞吐量方面具有更好的性
Abstract:
Mobile Ad hoc network is a special peer-to-peer network.Because of dynamic topology,openness of wireless channels,infrastructureless,it is vulnerable to various attacks,so the security issue is very essential to Ad hoc networks.Based on analysis of the existing security routing protocol,design a reputation evaluation mechanism,which composed of node＇s direct reputation value and indirect reputation value.However,for indirect reputation value,focus on the value obtained by the recent interaction.And last exploit a security routing protocol,called it SR-DSR.In this protocol select a path with largest value,the path reputation ratio of the length of the route to send the packets,to improve the reliability of packet＇s transmission.The simulation results show that SR-DSR protocol can get better performance in packet delivery ratio and throughput while there are attacking nodes in networks
