In mobile networks, sensing the geo information and retaining them around the location of interest is a challenging task. In particular, the geo information can only be obtained if the geo-cache holder is present in the anchor location. In order to keep the geo cache around the anchor location boomerang protocol is implemented. The protocol allows the current geo cache holder to keep the information with it until it moves out of anchor location. Using this protocol, the holder can handoff the geo cache to other candidates preferably those traveling toward the anchor location. For this purpose, each node maintains a trajectory segmentation stack.
