Now day’s mobile devices and the wireless devices which are connected with the Internet is rapidly growing. Wireless links as well as networks, both mobile users and the services which are related to the mobility form the growing Internet infrastructure part. Such kind of mobile parts as well as wireless parts are basically connected to the wider, larger networks. Mastering of the main concepts in wireless, mobile as well as wired technology. mobile IP in nothing but the Internet protocol which is defined by the IETF (Internet Engineering Task Force) which allowing end users to keep the same address for the IP, and connection is alive while switching from one network area to another one[1]. The important feature of the mobile IP design is that all needed the functionalities for the managing and processing information of mobility which is embedded in well defined entities such as Foreign Agent (FA), Home Agent (HA), Mobile Nodes (MN’s). Whenever the Mobile node moving from its HN (Home Network) to the FN (Foreign network), the packets correctly delivered to its present point of attachment based on the IP address of MN’s, which is changing during the new attachment point. Hence in order to ensure the delivery of packets to the MN, MIP allowing the Mobile Node to use the two IP addresses for the same such as care of address (CoA) as well as Home Address. Here the Home address is fixed or static which is assigned to the Mobile Node at the Home Network, whereas Care of Address is dynamic which representing the current Mobile Node location [2]. There are many problems which are associated with the basic Mobile IP like HA overloading, fault tolerance of home agent, triangle routing problem etc. Hierarchical Mobile IPv6 (HMIPv6) [2] was proposed by Internet Engineering Task Force (IETF) to mitigate the high signalling overhead that is incurred in Mobile IPv6 networks when mobile nodes ABSTRACT Mobile WiMAX is a wireless networking system based on the IEEE 802.16e standard. In order to support mobility some kinds of handoff schemes must be adopted and the hard handoff is defined as mandatory. Hard handover defined as break before make scheme where packet drop ratio is more. To avoid such packet dropping a route optimization scheme to be used to avoid the un-necessary network re- entry point. There are two type of route optimization scheme is there one based on IPv4 network called bidirectional symmetric route optimization and another one used in Hierarchical mobile IPv6 network called Adaptive Local Route optimization Scheme. In BSRO scheme network suffering from triangular Routing problem where handoff latency is increase and throughput goes down .In the ALRO scheme, an MN informs the CN of the MN’s LCoA, if the packet delivery cost is more dominant than the binding update cost. Otherwise, the CN is aware of only the MN’s RCoA. Namely, the ALRO scheme minimizes either the packet delivery cost or the binding update cost depending on the session-to-mobility ratio (SMR) of each CN. So using this scheme route is optimized between two nodes and triangular routing problem is solved, handoff latency decrease and less no. of packet drop. The ALRO scheme used in one MAP domain where in the simulation result show that throughput of network increases as comparison to BSRO scheme. Key Words: ALRO, BSRO,LCoA, RCoA
