Abstract:

Target tracking problem in DTN networks is a widespread concern, however, the current strategies mainly focus on a single detector tracking a single destination. Some strategies use the possibility that nodes encounter, some take advantage of the location information of nodes, and some adopt more innovative tools, such as the mobile location information and the time left by the target node. These policies make a direct or indirect use of the information of the destination node, however, the general not very high success rate makes their applications a subject to certain restrictions. We therefore present a distributed target tracking strategy based on multidetector collaborating named TMBC, which achieves multidetector collaborative tracking by the remote detection mechanisms DTRs and the close cooperative data exchange mechanism TRs. It can avoid conflict and redundancy detection to improve tracking efficiency. Theoretical analysis and experimental results verify that the proposal can effectively reduce the tracking steps to improve the success rate in comparison with the traditional methods.
