Providing Location Privacy to Base Station in Wireless Sensor Networks

Wireless sensor networks are ad hoc networks with sensing capabilities. Robustnessand Scalability of WSNs make them effective in many critical application areas likedefense. Security is the top most priority in such applications to keep the WSNfunctional for a long period of time. In our study, we attempted to counter a subsetof the security issues in WSNs - Location privacy of Base station(BS) in a WSN. Weproposed three novel methods- BLAST, APCAPT and hybrid method that combinesthe two techniques to provide location privacy to the Base station using power control(varying the power with which sensor nodes transmit their packets in a WSN). Thesetechniques protect the BS against Packet Tracing and Traffic Analysis attacks froma Local attacker and against a Global attacker to a certain extent. Through thesetechniques, we provide security while optimizing the use of energy throughout thenetwork while maintaining an optimal delay for reporting events to the BS. The ideais to vary the transmission ranges of a few or all of the sensor nodes in the WSN.By doing so, we ensure that the attacker cannot trace the packets to the BS usingthe strength and angle of arrival of the signal. We evaluate the performance of ourtechniques based on extra energy consumed and the network delay incurred whileproviding secured communication.
