摘要
无线传感器网络(WSN)在高连通度的条件下保证网络安全至关重要。提出一种基于多边形分组部署模型的密钥管理方案,该方案把监测区域划分成多个大小相等的n边形,对各n边形分组的性能进行比较,并提出基于最优模型树状结构的建立及密钥分配方案。理论分析与实验结果表明,该方案适用于大规模的WSN,在减少节点密钥存储量的同时,提高了网络的连通性。
Ensuring network security is crucial to wireless sensor networks under the condition of high connectivity. A key management scheme based on polygon grouping deployment model is proposed in the paper. The scheme divides monitoring area into a number of polygons with equal size, compares the performance of the polygons grouping and puts forward the establishment of tree structure based on optimal model and the key distribution scheme. Both theoretical analysis and experimental results show that the scheme is suitable for large-scale wireless sensor networks, it improves the network connectivity while reducing the key storage capacity of nodes.
