Description:	The increasing demands of Internet applications with mobility support give a great challenge in providing an efficient mechanism for mobile wireless access. The Internet Engineering Task Force (IETF) standardized the Mobile Internet Protocol (MIP) and MIP version 6 (MIPv6) to make the communication for the wireless access more efficient. However, the service quality of the MIPv6 is degraded because of extra signaling and long transmission due to latency resulted from excessive address translation. Hierarchical MIPv6 (HMIPv6) was introduced to achieve the best scalable solution for global mobility by dividing the world into domains. HMIPv6 regional registration adopted a Mobility Anchor Point (MAP) to control the visited Mobile Nodes (MN) in the domain to reduce the number of Location Updates (LU) in the home network. The MAP in the Foreign Agent (FA) area intercepts all the packets addressed to the MN and then tunnels them to the On-link Care of Address (LCoA) of the MN in the FA area. Nevertheless, HMIPv6 still unable to resolve the problem of scalability besides its high location updates cost, high packet delivery delay and large number of lost packets particularly when huge number of MNs visits the domain. The main objective of this thesis is to propose, analyze and evaluate an enhanced HMIPv6 called Smart Selection Hierarchical Mobile IPv6 (SSHMIPv6) to encounter those problems. SSHMIPv6 has a domain consisting of multiple MAPs using the same Regional Care of Address (RCoA) and each MAP in the domain is attached to an Access Router (AR). SSHMIPv6 environment have been simulated and used to evaluate the performance of SSHMIPv6 over HMIPv6 and to analyze the effect of adding multiple MAPs to serve each region using the Join Shortest Queue (JSQ) selection scheme. Then a load balancing strategy was introduced by ascendingly sorting the multiple MAPs having the same RCoA and attached with the same Access Routers in the SSHMIPv6 domains which adopt the HMIPv6 protocols. Simulation shows that SSHMIPv6 outperforms HMIPv6 in term of packet delay, lost packets, Goodput, and location update cost. In terms of the average packet transfer delay the average percentage reduction between using one MAP and two MAPs is 51 %. Taking into consideration the lost packet ratio, an average percentage reduction of 20 % was observed between when using one MAP and two MAPs. Finally, an application of SSHMIPv6, a concept of incorporated domains is simulated that allows adjacent domains to be incorporated together while keeping their MAPs sharing the same RCoA. It is found out that about 30% to 60% reduction in the location update cost was achieved. From the results above, we can conclude that SSHMIPv6 can solve the scalability problem because more mobile nodes are able to be handled and better served in the foreign domain.,Ph.D
