Research on Security Schemes for Wireless Sensor Networks

本文分析了WSN的安全问题,提出了一种新的WSN安全方案。此方案在网络初始化时采用预分配密钥方法来建立网络安全体系,减少通信开销,在网络运行时采用基于能量的动态分簇算法维护网络安全,优化网络生命周期。并且在这个基础上,提出了一种基于能量的多路径冗余传输来识别恶意节点。

In this paper, a new security scheme is proposed based on analyzing the problems the WSN. This scheme adopts the pre-allocation of the security key during the initiation of the of security in network, thus to reduce the communication overhead. And this scheme also employs a dynamic power-aware cluster order to maintain the security of network and optimize the life-time of the network. Furthermore, algorithm in a multi-pathtransmission scheme based on the energy is proposed to identify the malicious nodes.
