Privacy Preserving from global eavesdropper in Wireless Sensor Network Using Routing Technique

Abstract

Various sensor network security schemes care for the content of messages, while the related information is left defenceless by divulge the location of the monitored objects. Preserving location privacy is essential and one of the largely challenging problems in lots of mission crucial sensor network applications. Previous solutions are principally designed to defend privacy from regional attackers who eavesdrop on traffic in a petite region at a moment. However, they can be effortlessly defeated by abundantly motivated global attackers that be able to trace the entire network’s communication proceedings. Although a few topical privacy solutions are proposed adjacent to global attackers, they experience from significant communication transparency as they inject dummy traffic or send messages in a globally synchronized method. As a result, they devour a lot of energy to maintain a required privacy level that craft the network lifetime diminutive. We propose an energy-efficient source location privacy preserving solution, handle the Energy Efficient Location Privacy method beside global attackers (E-LPG). E-LPG hides inventive source locations through a spatial scatter of messages with stealthy wormholes and owing to a temporal scatter using random setback when endorsed With a imperfect number of wormholes, E-LPG can accomplish a high privacy level lacking incurring further communication overhead. We evaluated the effectiveness and efficiency of E-LPG owing to theoretical analysis and general simulations. We have shown that E-LPG also generate dramatic synergistic consequence when used among other privacy schemes accompaniment.
