动态分簇的异构传感器网络安全路由协议

当前很多无线传感器网络路由协议没有将安全因素考虑在内,而且一些已有的安全方案没有紧密结合典型分簇路由协议的运行机制,因此提出一种基于动态分簇的异构传感器网络安全路由协议(secure routing for dynamic clustering,SRDC).该协议在优先考虑能耗问题的基础上,通过多种安全机制实现密钥协商...

Dynamic cluster-based security routing protocol in HWSN

At present, many routing protocols of wireless sensor network do not take the safety factors into account, and some security schemes do not have close contact with a typical routing mechanism of cluster-based hierarchical wireless sensor network. Therefore, a security routing protocol named SRDC(secure routing for dynamic clustering) based on heterogeneous and dynamic cluster-based wireless sensor network was proposed. The new protocol, on the basis of energy consumption in the network, includes a variety of security mechanisms for key agreement, node authentication and efficient group key updates. Simulation results show that the protocol proposed not only can effectively prolong the network life time but also can greatly withstand conspiracy attack from attackers.
