Design and Implementation of a Fuzzy-Based System and a Testbed for Selection of Radio Access Technologies in 5G Wireless Networks

The transition to the 5th Generation (5G) mobile networks will rely on Ultra-Dense Heterogeneous Networks (UDHetNets). These networks introduce dense packed network configurations along with a diverse range of networks catering to user devices. The crucial challenge lies in establishing efficiently connections with an appropriate Radio Access Technology (RAT). This selection process involves the consideration of numerous parameters, which makes the problem NP-Hard. To address this challenge, in this research work, we design and implement a Fuzzy-based system and a testbed for RAT selection in 5G wireless networks. For the implementation, we consider three parameters: Coverage (CV), User Priority (UP), and Spectral Efficiency (SE). The output parameter is Radio Access Technology Decision Value (RDV).
