摘要
针对无线传感网络抵抗内部攻击能力薄弱的特点,提出一种基于依赖度的低功耗安全路由算法RAD(Routing Algo-rithm Based on Dependency),使网络能自主发现内部恶意节点,提高网络安全性,延长网络寿命。算法将依赖度应用于路由过程中,通过依赖度鉴别恶意节点,并设立通信黑名单,确保链路的可靠性。仿真及实验结果表明,算法有较高的检测率和较低的能耗。
According to the characteristic of wireless sense Network that the weak ability to against internal at- tacks, a safety of low-power routing algorithm RAD （Routing Algorithm Based on Dependency） has been proposed based on the dependency. It makes the network discovered internal malicious nodes independently, Improves net- work security, Prolongs the network lifetime. In the algorithm, the dependency has used in routing process and iden and tifying malicious nodes, and establish communication blacklist to ensure the reliability of the link. Simulation experimental results show that the algorithm has a higher detection rate and lower energy consumption.
