dc.description.abstractOne major challenge in the design of wireless mobile networks is the provision of quality of service (QoS) guarantees. Mobile users would require resources to be available in the cells they would move Into in order to maintain the same QoS as in the current cell. However, reservation in all neighbouring cells or based on the user's mobility history results in over-reservation of resources, leading to schemes that are very inefficient and unreliable. This dissertation presents a next-cell prediction scheme (NCPS) that uses a sectored-cell approach to predict a next cell, a mobile that will move into with an open connection. The NCPS was simulated and its performance was evaluated under different speeds of the mobile users. The behaviour of the scheme was also observed under different sizes of the critical region. The results of the scheme were also compared to the results of a representative history-based scheme. It was found that the NCPS performs better than the history-based schemes. The simulation results show that prediction accuracy can be achieved with a considerable decrease in the total tracking area of the network.en_US
