成簇阶段恶意节点识别与剔除模型研究及实现

Cluster identification and elimination of malicious nodes stage model and implementation

无线传感器网络节点成簇是实现对传感器网络高效节能管理和应用的有效途径。网络安全问题中恶意节点尤为突出,它们破坏网络系统的正常工作规则,影响网络的工作效率和整体存活寿命。为了提高网络的整体性能,希望能在网络成簇阶段及时将破坏作用的恶意节点识别出来并剔除。采用LEACH层次化网络通信思路,应用一种基于LEACH算法的密钥预分配方案,完成在成簇阶段对恶意节点的识别和删除的模型仿真从而有效的实现网络寿命的延长和网络效率的提高。

Wireless sensor network node cluster is an effective way to achieve energy-efficient of sensor networks management and applications.Malicious nodes in the network security issues is especially conspicuous.They destroy the normal work rules,thus affecting the efficiency of the network and overall survival life.In order to improve the overall performance of the network,we hope to spot Network Clustering phase in time and move it out is expected.With the ideas of LEACH-level network communication,this article applys a key pre-distribution scheme based on LEACH algorithm,to complete a model simulation to identify and remove malicious nodes in cluster stage,thus leading to the implementation of the extension of network lifetime and network efficiency.
