A SURVEY:LOCATION PRIVACY IN WIRELESS SENSOR NETWORK
Deewakar Samajdar, Toran Verma · Journal of Emerging Technologies and Innovative Research · 2015
Wireless device Network (WSN) is basically arrangement of distinct and dedicated sensors for observation and recording the healthiness of the surroundings and organizing the collected information at a central location. While several protocols for detector network security offer confidentiality for the content of messages, discourse info typically remains exposed. To conserve user location privacy, spatial and temporal cloaking techniques are the foremost ordinarily used technique in Location based mostly Services. Existing techniques defend the leakage of location data from a restricted opponent who will solely observe network traffic in a very tiny region. In previous papers, it was addressed the importance of location privacy of both the source and sink and propose four schemes called forward random walk (FRW), bidirectional tree (BT), dynamic bidirectional tree (DBT) and zigzag bidirectional tree (ZBT) respectively to deliver messages from source to sink, which can protect the end-to-end location privacy against local eavesdropper. Through analysis and simulation, we tend to demonstrate that the suggested techniques are efficient and effective for source location privacy in sensor networks.
