Abstract:
5G networks will have to cope with an increase of data traffic, as well as a vast number of devices, which already transpires in the wireless/mobile communication environments. Several on-going efforts both from 3rd Generation Partnership Project (3GPP) and several proposals from the literature as well, attempt to overcome the existing barriers by enabling the use of Wi-Fis and femto-cells. The evolution of Access Network Discovery and Selection function (ANDSF) in Evolved Packet Core (EPC) networks, as well as the Hotspot 2.0 approach, can be used to facilitate a seamless integration of WiFis with the cellular networks. Although this integration clearly presents benefits, a handover mechanism that will capitalize on the new standards is still missing. This paper acts in a two-fold way. We design and evaluate a novel context aware selection mechanism that is using fuzzy logic to select the most appropriate Radio Access Technology (RAT). To this end, we propose network extensions that allow the ANDSF entity to be aware and provide up to date information to end devices about the network status. Extensive simulation results illustrate the advantages of our approach.
