基于蚁群算法的无线传感器网络节点可信安全路由

针对无线传感器网络内部恶意节点可能产生的攻击，提出一种基于蚁群算法的节点可信安全路由协议，将节点信任评估模型引入到蚁群路由算法中，提高无线传感器网络的节点可信度，以节点可信度为依据隔离恶意节点，增强网络安全性。仿真结果显示，算法在网络丢包率、端到端时延、吞吐量和全网能耗等评价指标上都得到了显著的改善，对黑洞攻击具有较好的抵抗性能。

Node Credible Security Routing Protocol for Wireless Sensor Network Based on ACO

Aiming at internal malicious attack behaviors generated in the wireless sensor network,this paper pres?ents anode trustedsecurity routing protocol for wireless sensor network based on ant colony algorithm. In this proto?col,the node trust evaluation model is introduced into the ant colony routing algorithm to improve the network node credibility,and isolate malicious nodes and enhance the security of the wireless sensor network by the node credibil?ity. Simulation results show that our routing protocol can perform better in packet loss、end to end delay、throughput and energy consumption,and have a preferable resistance in black hole attack.
