In this paper we propose an efficient location management strategy called the profile-based two-level pointer forwarding cache scheme to improve the overall performance of the wireless mobile networks. It uses the two-level pointer for location update and the profile-based cache for call delivery. Location update for each Mobile Terminal (MT) is managed by the nearby Visitor Location Register (VLR) until it crosses the threshold of the number movements between Registration Areas (RAs). This reduces the frequency of accessing the remote Home Location Register (HLR) which eventually minimizes the location update cost by distributing its work. On the other hand, a profile of the MT's calling pattern is maintained in HLR and it is copied in the VLR caches from where majority of the calls are generated. These caches are searched first to find out the called MT's location in order to deliver a call. This delivery cost will be reduced if the location information is found in the caches since it does not have to access the remote HLR for searching the location information. The analytical modeling and numerical results show that the proposed method outperforms all other previous methods in terms of network signaling traffic load irrespective of the MTs' mobility and calling pattern.

Proxy mobile IPv6 (PMIPv6), which is a centralized mobility management protocol, are dependent on a local mobility anchor (LMA) to process all control and data traffics. Therefore, it has serious problems such as the tremendous traffic concentration into the core network and the triangle routing. In this paper, therefore, in order to alleviate these drawbacks, we propose a PMIPv6-based enhanced distributed mobility management scheme considering a user's traffic locality. Performance evaluation results indicate that in most cases, except for when a user's mobility rate is relatively very higher than the traffic rate, the proposed scheme shows better performance result than that of PMIPv6. Besides, it is demonstrated that the proposed scheme can be an effective alternative that can distribute the significant loads on the LMA of the core networks to the MAGs of the edge networks.

In urban cities, many MUs (mobile users) follow a fixed mobility pattern. Most of the time, these users can be found in a particular registration area (RA) at a certain time period. We say that MUs follow a fixed set of RAs on a daily basis. Therefore, an MU can be located at one of the RA from the set of fixed RAs when a call arrives. In prior schemes, the location update cost is minimized by increasing paging cost. In this paper, we propose a mobility agent (MA) and adaptive paging strategy based on MUs' movement. The MA is a special functional entity in the network, and many RAs are connected to MA as per mobility pattern of an MU. The paging area is selected based on the average speed of MUs. The major features of the proposed scheme are the overall reduced location management cost and less paging time compared with existing scheme. We present analytical modeling and performance evaluation that show that the proposed scheme has less location management cost and less paging time to locate an MU compared with existing scheme.
