Abstract

In ultra-dense network (UDN) scenarios the big number of users and dense placement is comparable to those of the Access Points (APs). In such UDNs new approaches for mobility management are necessary to ensure a reliable service provision, seamless connectivity and high unit area throughput. Dynamic access point grouping for user service provision is considered to be a core function of the UDN with user centric wireless access. In this paper, a heuristic approach with low computational complexity for AP grouping for mobility driven user-centric UDN is proposed, based on two general metrics reflecting the user density and distribution, user requirements and available resources in the APs. This allows the AP grouping process and user association to one or a group of APs to be represented as a dynamic service provision system and its performance as a function of user allocation, user mobility and user service requests to be more effective.
