Mobility management in three-tier SDN architecture for DenseNets
Ibrahim Elgendi, Kumudu S. Munasinghe, Abbas Jamalipour · 2016
Femtocells, which is one of the methods followed by 4/5G cellular system, are used for handling increasing data traffic in heterogeneous (HetNets) and dense networks (DenseNets). In this case, traditional mobility and session management approaches become obsolete and more appropriate methods need to be developed. Therefore, we propose a Distributed Mobility Management (DMM) and a User Rate-Perceived (URP) algorithms over a 3-Tier Software Defined Network architecture. Delay will decrease, throughput will increase, fast handover, reduce overhead signaling and avoid bottleneck by implementing these algorithms to solve the problems of mobility and session management, and capacity in DenseNets over the existing centralized mobility management in Long Term Evolution (LTE).
