一种基于迭代投票的无线传感器网络安全定位算法
摘要
绝大多数的定位算法都是基于信标节点的坐标信息计算未知节点的坐标信息
因此
信标节点的可信性至关重要。无线传感器网络在敌对环境中易受攻击
由此提出了一种安全定位算法。在算法中
节点间无需坐标交换
可直接迭代投票选出可信的信标节点进行定位
并通过仿真验证算法有效性。
Abstract
Majority of localization algorithms calculate coordinates of unknown nodes based on coordinate information of beacon nodes
therefore
reliability of beacon nodes is crucial. Wireless sensor networks( WSNs) is vulnerable to be attacked in hostile environment
a secure localization algorithm is proposed. In this algorithm
nodes don’t need to exchange coordinate information
it can choose reliable beacon nodes by iterative voting directly and the algorithm validity is verified by simulation.
