For privacy protection, many architectures such as trusted third party, cryptography, client side privacy etc. have been proposed. These methods are neither fully support privacy nor efficient. We have proposed limited broadcast based application and one dynamic protocol for cloaking. We have simulated user broadcast model, to achieve location privacy where users are mobile and points of interests (POI) are stationary. Second experiment is a POI broadcast model to achieve location privacy. We have also presented dynamic cloaking protocol that considers speed, direction & location of mobile user for cloaking. We have experimentally recorded the results related to performance, energy and privacy strength. It shows that our system has more social and human value along with commercial attraction. © 2016 The Authors.
