Virtual Node Based Location Privacy Protection in Wireless Body Sensor Networks

Abstract— In a wireless body area sensor network (WBAN), biosensor is used to collect the medical data. Data confidentiality is one of the crucial issues for WBAN application, many cryptography techniques are researched to achieve it. However, the adversary can obtain some important information by eavesdropping the pattern of data transmission without detecting the context of data. In addition, the adversary can also infer the location according to the Received Signal Strength Indication (RSSI) values received. In this paper, based on our previous work--PAS, we propose a coordinator for further location privacy protection. This coordinator is a virtual node which has leverage on RSSI values and discombobulates the signals that the adversary receives. The experimental results show that the coordinator protects WBAN users from differential RSS attack and the energy consumption is reasonable.
