....registers (databases) are used to store the location of mobile users and use this information whenever a call has to be delivered to a MT. Mobile P PNNI Schemes: New features are added in the PNNI protocol to achieve the required mobility support. Mechanisms of the first category (e.g. [KRI96], lAKY96] HAC97] VEE97] POR97] use databases that store the location of MTs. Most of these mechanisms are based on IS 41 [IS41] and GSM MAP [MOU93] which they try to improve with the use of forwarding pointers and dynamic location update strategies. Location tracking always precedes the ....

....registers consisting of the Home Location Register (HLR) and the Visiting Location Register (VLR) The HLR stores the location and the profile of a user. The VLR maintains the same information locally, for a roaming subscriber, and notifies the appropriate HLR about the location of visiting MTs. [Kri96] suggests the use of forwarding pointers in addition to the HLR to assist in location management. According to this mechanism, for each MT that crosses the boundaries of a registration area, its related information (e.g. user profile) is transferred to the new location server (LS) In addition, a ....

.... would be more preferable for the mobile users to set up communication links between themselves without any static network interaction [3] In the current existing proposals for mobile wireless networks, routing information of each mobile host is maintained in some database (HLR and VLR in IS 41 [5, 6], home agent and foreign agent in mobile IP [8, 9] which is located in the static network. However, there is no such database available for ad hoc networks. Due to limited range of the wireless transreceivers, a mobile host can communicate with another host only within a limited geographical ....

Research reported is supported in part by AFOSR. Preliminary version of this report appears as technical reports [17, 18]. y Direct all correspondence to P. Krishna. 1 Introduction It is expected that existing wireless cellular networks will be upgraded for personal communication services (PCS) 7, 9, 21] An important issue in mobile wireless networks is the design and analysis of location management schemes. ....

....from any location within the area of radio coverage. Mobility is an important new component that will have far reaching consequences for system design. An important issue that stems out of mobility of hosts is design and analysis of location management schemes in infrastructure networks [36, 37, 49, 50, 57, 58]. In dynamic networks, mobility of hosts causes the network topology to change. This in turn complicates the design of routing protocols in such networks [16, 39, 47, 59, 61] Mobility also affects the design of applications. In a client server environment, mobile clients may find themselves far ....

....algorithms to estimate r based on the history of call and mobility patterns. The basic assumption behind these algorithms are that past history of the user s call mobility patterns will reflect the behavior in future. I. Comparison with Other Centralized Schemes Our work presented in this chapter [49, 50] differs from other centralized schemes [36, 37] in the following respect: ffl A new heuristic (search based) is proposed in this work. In [37] only movementbased heuristic is discussed. 87 ffl This chapter studies the impact of combining forwarding and caching on the perfomance. We show that ....

.... For a typical personal communications network, it was determined that the memory required at the first level (the parents of the leaf level nodes) location servers for PI equal to 1 hour, was about 340 Kbytes when no search updates were used, and, about 840 Kbytes when jump updates were used [5]. Let the current time be curr time. If fp time 6= NULL, and curr time Gamma fp time PI , then the entry for the host is purged from the MSS 4 . If curr time Gamma fp time PI , it means that there is some other host in the system which has recently used the forwarding pointer information of ....

....is the total cost, defined as the sum of average update cost, average search cost, and the average search update cost. Other cost metrics are also possible. For instance, in our further work we use total cost (sum of search cost, update cost and search update cost) per move as a cost metric [5]. 5.3 Results Simulations were performed to analyze the performance of the various location management strategies. Results were obtained for the two type of environments, Type (i) and (ii) The values of C and M were both varied from 1 to 15 units of time. Value of C was changed to vary the ....

....establishment phase by sending a connection request message to its base station. The base station forwards this message to its switch. The switch assigns a VCN (virtual circuit number) for the source mobile host. The switch then initiates a locate procedure for the destination mobile host [10, 11, 12]. Upon getting the location information of the destination mobile host, a connection is set up between the source and the destination mobile host via the switches at the source and the destination. Our work differs in the connection maintenance phase. Please refer Figure 9 for the discussion. The ....
