摘要: 现有无线传感器网络的源节点位置隐私保护协议采用随机游走的方法,导致能耗难以控制。针对这一问题,本文提出一种基于可控能耗的源位置隐私保护协议(CEP)。该协议以节点间物理距离为路由能耗的衡量标准,利用可控的路由能耗建立源节点到基站节点间3段路由转发源数据包。协议通过幻影路由、环带路由、信贷路由3个阶段增加路由路径的多样性,从而增加源节点位置隐私保护强度。理论分析和仿真实验表明,本文提出的基于可控能耗的源位置保护策略相比已有相关协议在提高源节点安全周期的同时,可较好地控制路由能耗,提高隐私保护协议的性能。

Abstract:  Existing source location privacy preserving protocols applied to WSN use random walk, and the routing energy is hard to control. In order to solve this problem, this paper proposed a protocol based on controllable energy consumption (CEP). The proposed protocol took the distance of nodes as measure of energy consumption and created a 3-phase route between source node and sink node using controllable energy consumption. CEP increased the diversity of the routing path through phantom route phase, annular route phase, and credit route phase. Theoretical analysis and simulation experiment show that, the proposed strategy enhances safety of source node and controls the energy consumption.
