Abstract: In the wireless networks, the handoff procedure has a significant impact on the system's performance. In this dissertation an opportunity-cost concept based approach for adaptive bandwidth reservation with admission control for handover calls, is used. Excessive reservation guarantees low call dropping probability of handover calls at the cost of high blocking probability of new calls. A method of improving the quality of service of wireless network based on the mathematical optimization of the bandwidth reserved for handoff connection is presented. The objective here is to improve the quality of service of the wireless network by minimizing the forced termination probability of handover calls. Analysis of the method, which uses a small queue of size MAXQUEUE with a maximum queuing time At, has been done. New calls are blocked directly if bandwidth is not available to precede the connection. Handoff request are queued if required bandwidth is not available at the time of arrival. The performance criteria of interest are: Probability of forced termination of handoff calls, probability of new calls blocking and infliction (newly defined QoS parameter), and idle bandwidth. Previously purposed policies for improvement in QoS are compared with the scheme presented here. The presented scheme is seen to provide lower probability of forced termination, lower call blocking probability and lower total infliction measurement. The implementation is done in C language on Pentium IV system under windows-98 environment. III
