....In order to reduce the total cost in location management, various location update generation schemes based on the mobile terminals call and mobility patterns have been proposed. They include the time based [1,2, 3] the movement based [4,5] and the distance based [6] schemes. Numerical results in [7] show that the distance based update scheme may give a better performance in terms of a lower total cost for location update and paging as comparing with the timer based and movement based schemes. In order to further reduce the location management cost, various schemes by exploring the mobility ....

....of the model in Figure 2. In this example, the MN travels for a total of 10 steps (instead of 60 seconds) before changing its direction and speed. Unlike Figure 1, each movement of the MN in Figure 2 is the exact same distance. The Random Walk Mobility Model is a widely used mobility model (e.g. [2, 11, 27, 34]) which is sometimes referred to as Brownian Motion. In its use the model is sometimes simplified. For example, 3] simplified the Random Walk Mobility Model by assigning the same speed to every MN in the simulation. The Random Walk Mobility Model is a memoryless mobility pattern because it ....

....the average location update cost for centralized fixed WF B X O7P 2 Q B 5 . O7P 2 Q B V (8) For distributed GFA system architecture, the MN will move out of a regional network only after it has visited all the subnets. Previous researchers used either Markovian model [15] or random walk model [10] 11] 16] for probability analysis. However, the movement of MNs for distributed scheme is not a Markov process because the decision of whether an MN can move out of a regional network depends on its mobility history, i.e. whether an MN is in another regional network ....

....factors, paging delay is very important as the quality of service (QoS) requirement for multimedia services. Paging cost, which is measured in terms of cells to be polled before the called MT is found, is related to the efficiency of bandwidth utilization and should be minimized under delay bound [3,5]. In this paper we focus on the paging problem, that is, to reduce the paging costs under delay bound. According to the current GSM and IS 41 protocols being used in paging process, paging is accomplished through a broadcast or onestep procedure [10,14,19] Each service area is divided into many ....

....rise to the need of locating mobile devices which is the aim of a location management service. The tracking problem exhibits an inherent tradeo between the load imposed on the system by devices reporting their location and the load imposed when the system searches for devices (see for example [5]) To illustrate, let us assume that each terminal reports its location by sending a message over a wireless link to the base station every time it enters a new cell. This means that the system has up to date information about terminal location and when call is to be established the system does ....
