摘要
针对当前MANET安全机制研究中过于关注机密性和完整性而忽略可用性的问题,该文指出在MANET这样无中心、动态拓扑、资源受限的环境中,信任模型是最为合理的安全解决方案,从而提出基于可用性的信任模型。并在此基础上,以网络数据包的传递作为信任参考依据,对传统的AODV路由协议进行了改进,提出了ATAODV路由协议。网络模拟实验的数据显示基于可用性信任模型的ATAODV相对于传统AODV,丢包率平均降低了70.2%。
Traditional security research of mobile ad hoc network(MANET) focuses on the information confidentiality and integrity but ignores the availability.This paper notes that the best security solution for center-less,dynamic and resource-constrained MANET is the trust model.An availability trust model was then developed based on the packet forwarding in the network to improve the ad hoc on-demand distance vector routing(AODV) protocol,named availability trust AODV(ATAODV).Simulations show that the packet loss ratio of ATAODV declined by 70.2% compared with that of AODV.
