1D-S Evidence Theory Based Trust Ant Colony Routing in WSN显示文摘This paper proposes a trust ant colony routing algorithm by introducing a node trust evaluation model based on the D-S evidence theory into the ant colony routing protocol to improve the security of wireless sensor networks. To reduce the influence of conflict evidences caused by malicious nods, the consistent intensity is introduced to preprocess conflict evidences before using the D-S combination rule to improve the reliability of the D-S based trust evaluation. The nodes with high trust values will be selected as the routing nodes to insure the routing security, and the trust values are used as heuristic functions of the ant colony routing algorithm. The simulation tests are conducted by using the network simulator NS2 to observe the outcomes of performance metrics of packets loss rate and average end-to-end delay etc. to indirectly evaluate the security issue under the attack of inside malicious nodes. The simulation results show that the proposed trust routing algorithm can efficiently resist malicious attacks in terms of keeping performances of the average end-to-end delay, the throughtput and the routing packet overhead under attacking from malicious nodes.Ziwen Sun Zhiwei Zhang Cheng Xiao Gang Qu 2018China Communications2018,15,3:1
2无线传感器网络匿名通信技术研究进展显示文摘信息安全(内容安全和通信安全)一直是无线传感器网络(WSN)研究与应用关注的热点.由于传感器节点能量、计算和内存限制以及部署环境的特殊性,WSN难以适用复杂度高的安全算法.内容安全可通过加密方法和认证机制来实现,而匿名通信技术是实现通信安全与隐私保护的一种有效方法.通过对传统匿名通信技术和WSN匿名通信机制的调研,分析了WSN关键匿名通信技术的优缺点,并进行了总结和展望.房卫东 李凤荣 单联海 何为 王营冠 2017北京邮电大学学报2017,40,1:1
