Personal location monitoring with an untrusted server that invent previous threats to the individual monitor for this privacy leakage. The authors implement privacy preserving location monitoring services in WSN. In this paper, they design two algorithms that is resource aware and quality aware algorithm the aim of both this algorithm is to provide high quality location monitor services to the user. The resource aware algorithm used for to minimize communication and computational cost and the quality aware algorithm used for to maximize the accuracy of the aggregate location and minimize their monitor areas .these both algorithm depend on the k anonymity privacy concept, this concept require each person is indistinguishable among k person k anonymity privacy concept maintain aggregate location information.
