IEEE 802.16 network protocol is designed to provide a Worldwide Interoperability for Microwave Access (WiMAX). Due to limited bandwidth and an expensive radio spectrum available for communication, it is necessary to use one bandwidth more than one time in a same network when it became unused. For that purpose “Bandwidth Recycling” concept is introduced. The spectrum (bandwidth) is specifically allocated by agency to various users, but many times it is seen that the spectrum is not fully utilized by the users in the specific interval. This unused bandwidth can be allocated to other users who demands for more bandwidth for that specific interval without changing existing bandwidth scheme. In this paper we analyse different algorithms which does the recycling of bandwidth as per need is presented. To recycle the unused bandwidth priority based scheduling (PSA) algorithm has been developed & to improve the recycling effectiveness rejected bandwidth request first algorithm (RBRFA) and history based scheduling algorithm (HSA) are outlined. By implementing these all algorithm in Netbean (Version 7.4) Simulator, we have evaluated the performance of our system. Our simulation and analysis result confirmed that the proposed system can recycle unused bandwidth.
