Resource Aware Location Monitoring Anonymization System for Wireless Sensor Networks

Abstract: Anonymzing wireless sensor networks allow users to access services from the server. In the network there can be a solitude threat of which users can view the content of the other users. Users can even modify copy or perhaps delete the information. To enable trusted sensor nodes to provide the aggregate location information of monitored persons for our system. Each aggregate location is in a form of a monitored area A along with the number of monitored persons residing in A, where A contains at least k persons. The resource-aware algorithm aims to minimize interaction and computational cost. To utilize the aggregate location information to provide location monitoring services, we use a spatial histogram approach that estimates the allocation of the monitored persons based on the assemble aggregate location information. Then the predictable distribution is used to allow location monitoring services through answering range queries. We evaluate our system through simulated experiments. The results show that our system provides high quality location monitoring services for system users and pledge the location privacy of the monitored persons.
