Improving quality of service in Worldwide Interoperability for Microwave Access networks using spectrum-sharing technique

There is a huge demand for data as subscribers are becoming very familiar with mobile devices and its applications. A huge amount of data is being transmitted and received as this communication goes on. It is imperative that with the limited resources available to the network operators, the spectrum through which all these data is used is managed efficiently. This has brought about the need for network providers to combine their resources to furthermore provide a better quality of service to subscribers. Sharing the spectrum in which they operate is one way of solving this problem. In this study, we consider the benefits of sharing a redundant spectrum bought by two network providers who have come in an agreement to use it judicially when it becomes necessary. The parameter used for the analysis are throughput and blocking probability. A comparison is done using these two parameters with respect to the direct link and the spectrum shared link. In our findings, the spectrum sharing scenario proposed, was really efficient when facing issues with blocking probability and throughput by given an optimum of 0.0501 and 21.4Mbps respectively at 20% traffic load, thus increasing the quality of service of the system. This shows how better off it would be for network operators to share their resources as it provides a better quality of service to the subscribers.
