TPRLM: Time-based Probabilistic Relational Location Management Scheme for Wireless Cellular Networks

Locating mobile nodes and delivery of inward calls to that node in wireless cellular networks, in spite of extreme mobility of the nodes, is a challenging issue. Fast and error-free delivery of packets to perfect destination with good performance in wireless environment is extremely difficult to attain. Several available location management schemes incur huge location update cost, paging cost and network bandwidth wastage in attempt to achieve it. They also offer significant location update delay and paging delay. Interactivity and great efficiency are also lacking. In this paper, the framework of a scheme TPRLM is proposed. This scheme combines relational level-based coverage area management with organized Informing Cells and time-based probabilistic priority calculation based on inward call arrival rate of any node. The scheme tries to attain cost-effectiveness, reduced location update delay and paging delay. There is also scope for interactivity and improved performance without complexity.
