一种基于时空相关性的WSN安全路由协议

摘要

针对现有无线传感器网络中存在的许多路由协议仅考虑节能因素而没考虑安全因素，而那些专门为安全而设计的路由协议存在开销较大、算法复杂等问题，提出一种安全节能的分簇路由协议TLEACH-STC。该协议在TLEACH的基础上，利用WSN中数据之间具有的时空相关性，使上述问题得到很好的平衡。实验结果表明该协议的有效性。%Introduces a new secure and energy saved routing protocol TLEACH-STC, it is focused on existing issues of protocols in wireless sensor networks what just considered energy saving only without security concern or designed for security only ignored large overheads and com-plex algorithm, so on. Considering temporal-spatial correlation of sensed data, this protocol is built up based on TLEACH protocol. It bal-ances above existing issues of protocols in WSNs. Simulation results show that the new routing protocol is effective.
