Additive Logarithmic Weighting HetNet Selection Method for Video Services over 5G Networks

5th-Generation (5G) applications require high data rates and Quality of Service (QoS) levels. Mobile devices can access the Internet exploiting several technologies, as for example Long Term Evolution (LTE) or Wireless Fidelity (WiFi). In this context, the heterogeneous network (HetNet) paradigm has been introduced to allow the coexistence of devices and services with different characteristics assuring a high QoS level to users without modifying resource distribution and management. Several access network selection methods have been proposed showing the limitation of not considering both the type of traffic for the service requested by users and the characteristics of devices. To overcome this limitation, a new HetNet selection method based on additive logarithmic weighting (ALW) algorithm is presented in this paper, combining information related to the received signal power, network load, and mobility of users.
