Ad Hoc网络自适应安全加权分簇算法

摘要

为解决Ad Hoc网络分簇过程中恶意节点被选为簇首带来的安全隐患，保障Ad Hoc网络的正确分簇和稳定运行，提出基于节点相关度、相对移动性、剩余能量值、安全评估度量值多方面因素的自适应安全加权分簇算法。安全评估度量参数由外部入侵检测系统和内部节点信任度共同计算得到，确保安全因素在分簇过程中的准确性；基于该算法给出相应分簇管理过程。仿真结果表明，该算法能够改善分簇性能，提高Ad Hoc网络的安全性。%To eliminate the hidden danger of electing malicious nodes being the cluster heads during clustering and to guarantee the correct clustering and the stable operation of the Ad Hoc network ,a new adaptive safety weighted clustering algorithm was proposed based on the degrees of nodes ,the relative mobility ,the residual energy value ,and security evaluation metrics .To ensure the accuracy of the safety factor during clustering ,the security evaluation metrics were calculated by using both external intrusion detection system and the internal nodes trust degree .The clustering management process was proposed based on this algorithm .The simulation experimental results show that this algorithm can not only optimize its clustering function ,but also improve the safety of Ad Hoc networks significantly .
