Routing for Enhancing Source-Location Privacy in Wireless Sensor Networks

摘要

PURPOSE: A routing method for enhancing source location privacy in a wireless sensor network is provided to reinforce location secrete of nodes adjacent to managed targets which location is revealed by adjacent pursuer within predetermined distance. CONSTITUTION: A greedy forwarding method and random routing method is performed in the respective constant probability(S117,S105). The greedy forwarding method points to a shortest distance routing. The random routing method randomly unfolds route for the predetermined hop. In case of message gets near the idle sources during the performance of the random routing method and greedy forwarding method, the location of the idle sources is protected through the detour of the boundary area from pursue of the pursuer(S121,S123).
