Review on Efficient Reuse of Bandwidth for Throughput Enhancement in IEEE 802.16 Networks

摘要

IEEE 802.16 is a standard supporting applications demanding bandwidth. Bandwidth reservation and usage depends on the type of the application. Transmission rate varies with respect to transmission medium and traffic. If the amount of bandwidth reserved is less and actual load is more then the data may be distorted or lost. For this efficient Reservation scheme is required [1][2]. If the amount of bandwidth reserved is more and actual load is less then the reserved bandwidth may be wasted [6]. In this paper we discussed several mechanisms for better bandwidth reservation schemes and reuse mechanisms. We also discussed the concurrent transmission sachems for throughput enhancement. Efficient bandwidth reservation schems like Dynamic reservation schems are used. Here the bandwidth reuse mechanism is achieved without affecting the Quality of service applications in the system. So the mechanisms discussed are QoS guaranteed services.
