摘要
研究并设计一种超半数"投票"方案。以簇头为计票者,认证结点为投票者,由簇头搜集与统计"选票"信息。依据超半数投票原则得出统计结果,断定可疑结点的真实性。通过理论推导和计算证明,在异构的传感网络中,投票统计结果的可信度达90%以上,能够准确、可靠地检测出可疑结点,提高无线传感器网络的安全。
A majority voting scheme is researched and designed in this paper. It adopts cluster-head as counter and uses attested nodes as voters. Attested information is collected and counted by cluster-head. The result of voting which adopts the majority voting principle to calculate decides on the authenticity of suspicious node. Through the theory deducing and computation test, in heterogeneous sensor network, it can be demonstrated that reliability of voting can surpass 90%. Thus, the voting scheme can detect suspicious node more accurately and reliably, and improve the security of wireless sensor network.
