Matching With Externalities for Context-Aware Cell Association in Wireless Small Cell Networks
In this paper, the authors propose a novel approach for user-cell association in wireless small cell networks that exploits previously unexplored context information extracted from the users' devices, i.e., the User Equipments (UEs). In particular, beyond including precise QoS requirements that account for the application usage of the UEs, their cell association approach accounts for the devices' hardware type (e.g., Smartphone, tablet, laptop). This novel approach has the practical benefit that it allows the small cells to make better informed cell association decisions that exploit practical device-specific QoS requirements and characteristics. They formulate the problem as a matching game between the SBSs and the UEs.
