Interference Estimation and Mitigation in Wireless Networks

Abstract

To improve the resource utilization, the world of wireless communication network has seen suggestion and developing of new frameworks targeting an improved model of resource usage in wireless space by enabling cooperation and collaboration among possibly interfering wireless technologies in a dynamic and adaptive fashion. An important element of the cooperative framework is the discovery and learning process. The optimization mechanisms the framework will become to support strongly depend on the scope of information and observability of the system. An important part of this information is the effect of wireless networks on each other which is called the “inter-network interference” information. However, there are doubts in the research community on the efficacy or/and correctness of existing interference model for wireless networks. In this paper, the coexistence performance of wireless networks is analyzed in terms of throughput and packet reception ratio. It has been found that while SINR-based interference model necessities including other factors as the interferer's traffic rate, radio design etc. to be more realistic. The process of estimating this relationship is an expensive process and the question has been asked in this project is weather the framework should attempt to gather this information?
