Partial overlapping channels are not damaging
Journal Title: Journal of Networking and Telecommunications - Year 2019, Vol 1, Issue 1
Abstract
We know that in many different technologies, many wireless channels will be partially overlapped. However, due to the interference effects in such partial overlapping channels, they are often avoided using them simultaneously. In this paper, we propose to use the method of the system for the first time to try to simulate some overlap between channels. Through this model, we show that the use of partially overlapping channels is not always harmful. In fact, if careful use of some of the overlapping channels often leads to significant improvements in spectrum utilization and application performance. We demonstrate this view through analysis, as well as through detailed application layer and MAC layer measurements. In addition, we illustrate the benefits of the model we developed by using it to directly enhance the performance of two previously proposed channel allocation algorithms - in wireless LANs and other in multi-hop wireless mesh networks. Through a detailed simulation, we show that in these two cases, the use of partially overlapping channels can improve the application throughput factor of the terminal to the terminal between 1.6 and 2.7, depending on the wireless node density. Finally, we observe that some of the overlapping concepts can be flexibly designed to design efficient channel access mechanisms in emerging software radio platforms.
