Enhanced Paging Mechanism in IP-based IMT Network Platform (IP2)

IP2 (IP-based IMT Network Platform) is a ubiquitous platform supporting mobility using two step IP address IPha (IP host address) and IPra (IP routing address) - in a backbone network. MN (Mobile Node) in IP2 maintains either Active or Dormant state, which is transferred to Active state through Paging process when communication is required. In this paper, we proposed a Paging method using proxy to resolve the problem of the conventional Paging method which transmits the Paging messages to all cells in LA (Location Area) resulting in the excessive use of network resources. Performanceevaluation of the proposed method using NS-2 showed that the usage of network resources becomes more efficient by reducing paging loads, especially under the condition of increased nodes.
