DISTRIBUTED MOBILITY MANAGEMENT FOR TARGET TACKING IN MOBILE SENSOR NETWORKS

[ask1990]

Abstract:
The project Distributed Mobility Management for target tracking in mobile sensor Network proposes scalable, robust, efficient location database architecture based on the location- independent PTN. For mobile sensor networks that are deployed for surveillance applications, it is important to use a mobility management scheme that can empower nodes to make better decisions regarding their positions such that strategic tasks such as target tracking can benefit from node movement. In this paper, we describe a distributed mobility management scheme for mobile sensor networks. The proposed multi-tree database architecture consists of a number of database subsystems, each of which is a three-level tree structure and is connected to the others only through its root. Location management procedures involve numerous operations in various databases. These databases record the relevant information of a mobile user, trace the userâ„¢s location by updating the relevant database entries, and map the userâ„¢s PTN to its current location.
