In case of variable bite rate application, the subscriber station requires bandwidth for downlink and uplink of data transmission. As subscriber station cant estimate how much data it wants and to ensure the QOS guaranteed services, It may reserve more bandwidth than its demand. As a result, the reserved bandwidth may not be fully utilized all the time. Hence there is a wastage of bandwidth. This paper consists of a scheme named as 'Bandwidth Recycling', to recycle the unused bandwidth without changing the existing bandwidth reservation. In this scheme the subscriber station will used the available unused bandwidth. By this system throughput can also increase while maintain the same quality of services. In this scheme we use mathematical analysis and simulation. And this results in the scheme can recycle 35% of unused bandwidth on average. The extension for this project can also be showed by the three scheduling algorithms. Thus the simulation results to improve overall throughput by 40% in a steady network.
