基于最小能耗路由的源节点位置隐私保护协议

Source-Location Privacy Protocol Based on the Minimum Cost Routing

源节点的位置隐私保护已经是制约着无线传感器网络推广的关键技术之一。同时,能源问题又是一个很大的约束,所以人们一直致力于在位置隐私保护和能量消耗之间寻找一个平衡点。本文一种基于最小能耗路由的源节点位置隐私保护协议,协议分为两个阶段:第1阶段,源节点通过定向随机步的方式以额定能耗快速地向幻影节点转发数据;第2阶段,幻影节点以避开源节点可视区的最小能耗路由向Sink转发数据。实验表明,提出的路由协议以较小的能耗达到了较高的隐私保护要求。

Source-location privacy protection is already one of the key technologies which restrict the promotion of wireless sensor network （ WSN ） . At the same time, the energy issue is also a big constraint, so we have been committed to find a balance between privacy protection and energy consumption. In the paper,we proposed a source-location privacy protocol based on the minimum cost routing（ LPBMR） . The protocol is divided into two parts：In the first phase,The data is sent to the phantom node with directional random walk at a certain energy consumption;In the second phase,the phantom node send the data to the Sink along with the minimum energy routing which can avoid the visual of the source node. The results of the simulation showed that LPBMR can achieve a good privacy protection with less energy consumption.
