摘要： 传统的无线传感器网络位置隐私保护算法没有很好地实现安全性与网络能耗之间的均衡.为了解决这个问题，提出了一种基于扇形区域的随机中继节点路由算法，通过调整扇形区域的大小来控制路由路径的范围，并采用随机选取扇形子区域作为下一跳路由节点可选区域的机制来实现源节点的位置隐私保护.仿真实验结果表明，与幻影路由等其他路由算法相比，所提的路由算法可以在不影响数据投递率的前提下，有效地保护源节点的位置隐私，网络能耗较少.同时，该算法具有较好的灵活性，用户可根据实际需求设置高安全性或低能耗模式.

Abstract: The traditional location privacy protection algorithms in wireless sensor networks can not get a well balance between the security and network energy consumption. To resolve this problem， a routing algorithm of random relay node was proposed on the basis of the fan-shaped region. The range of routing path was controlled by adjusting the size of the fan-shaped region. In order to protect the location privacy of the source node， a mechanism was adopted which could randomly select a fan-shaped sub-region as the optional area of the next hop. Simulation results showed that comparing with Phantom routing and other routing algorithms， the proposed algorithm can effectively protect the location privacy of the source node without affecting the data transmission ratio， and has lower energy consumption. At the same time， the algorithm has better flexibility， and the high security or low energy cost mode can be set according to the practical demand.

Key words: wireless sensor networks, location privacy, dynamic routing, random fan-shaped sub-region, low energy consumption
