A Survey On Tying Data To Geographic Locations In Mobile-Disconnected Networks Using Boomerang Protocol

Abstract: We provide a protocol which retain content of information even in mobile disconnected networks without using infrastructure networks. As the mobile device keep the content information for a short period of time the boomerang protocol provide a efficient method to retain it and using a method called trajectory it records each geographical location while moving away from the sensing location. The performance result show that the trajectory algorithm is more efficient and Using this protocol, the holder can handoff the geo cache to other candidates preferably those traveling toward the anchor location.
