Performance Evaluation Of Macro 26 Micro Mobility In HMIP Networks

Abstract Changing the location of mobile node during transmission or receiving of data always caused changing of the address of the mobile node which results in packet loss as well as delay in time taken to locate the new address of the Mobile Node therefore delay of data receiving is caused this problem was known as micro-mobility issue. To resolve this problem and ascurrently mobile IP is the most promising solution for mobility management in the Internet. Several IP micro mobility approaches have been proposed to enhance the performance of mobile IP which supports quality of service minimum packet loss limited handoff delay and scalability and power conservation but they are not scalable for macro mobility. A practical solution would therefore require integration of mobile IP and micro mobility protocols where mobile IP handles macro mobility and HMIP cellular IP HAWAII handles micro mobility. In this paper an integrated mobility management protocol for IP based wireless networks is proposed and analyzed.HIERARCHICAL MICRO MOBILITY PROTOCOL is used. To identify the impact of micro-mobility in IP based Wireless Network to implement selected micro-mobility model of Hierarchal Micro Mobility Protocol in network simulator and for more analysis and measurements results and for the purpose of performance comparison between both Macro and Micro mobility Protocol Management.. Simulation results presented in this paper are based on ns 2
