Analysis of Location Monitoring Techniques with Privacy Preservation in WSN

The trend of location surveillance system is increasing day-by-day, so the range of such services providing systems like GPS and PDA´s conjointly increase parallel. As a result of this, we tend to get the precise and applicable location of monitoring object. However at an equivalent time the foremost necessary issue of privacy is missing. WSN chiefly consists of spatially distributed autonomous sensors that monitor physical or environmental conditions and cooperatively pass their data through the wireless network to a main location in WSN. The main challenges in wireless sensor network are heterogeneousness, distributed processing, low bandwidth communication, large scale coordination and secured location monitoring. There is a variety of applications that are developed on the basis of wireless sensor network, such as navigation, habitat monitoring, objects detection and tracking. Location monitoring systems are used to detect human activities and provide monitoring services with low privacy. This paper gives comparative analysis of the location monitoring and privacy providing schemes. There are some problems in previous papers that are: wrong location providing, provide precise location except privacy, providing privacy as well location except the data used is static data. The method proposed in this paper is more reliable to overcome such problems.
