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. If the amount of bandwidth reserved is more and actual load is less then the reserved bandwidth may be wasted. In this paper, the authors discussed several mechanisms for better bandwidth reservation schemes and reuse mechanisms. They also discussed the concurrent transmission sachems for throughput enhancement.
