Resource and Quality Aware Location Anonymization Mechanism For Wireless Sensor Networks

A wireless sensor network is a heterogeneous network consisting of a large number of tiny low-cost nodes and one or more base stations. These networks can use in various applications like military, health and commercial. However, the privacy preservation problem has drawn huge attention in the research community. This problem is exacerbated in the domain of WSNs due to the extreme resource limitation of sensor nodes. In this paper, we proposed a model for privacy preservation for mobile users by using anonymization and aggregate location monitoring in a wireless sensor network. Resource-aware and quality-aware anonymization algorithms are designed to preserve personal location and provide location monitoring services. Sensor nodes execute location anonymization algorithms to provide k-anonymous aggregate locations. To evaluate the performance of the proposed algorithm we simulate it in the NS2 simulator. Our experimental results show that proposed solution provides high quality location monitoring services for end users and guarantees the location privacy of the monitored persons.
