Wireless sensor networks concerned with localization of sensor nodes with least errors extracts more attention of the people. Localization with mobile anchor points makes it easier to locate static nodes using GPS technique. Many methods have been developed to minimize the localization error but failed to achieve the accurate results. This paper describes a survey on range free localization using with mobile anchor points. Each anchor point equipped with GPS moves in sensing field with a particular trajectory such as scan, double scan and Hilbert and broadcasts its current position periodically.
