Abstract

User-centric communication in fifth generation (5G) network enables wireless peer-to-peer network interface between mobile users in order to improve the data rate and offload the traffic for improved QoE as compared to traditional legacy base station centric (network centric or eNB centric) architecture. In this paper, we introduce a user-centric performance based cooperative cellular communication architecture and device mobility management procedure for 5G networks. Due to the exponential growth of connected devices, the users are deployed very densely. It motivate the researcher for user-centric communication, and it is a feasible approach, where the user can communicate via a relay node with minimum network infrastructure support. The proposed approach is central to mode switching and supporting a high degree of user mobility during the communication. The mode switching techniques is depends on quality parameters (such as link utilization, delay, and energy consumption). When the network switches the communication link from traditional mode (network centric) to user-centric mode of communication, it resort to relays to sustained the quality parameters. The relay selection is a random process, the network selects an arbitrary node as a relay node without any negotiation on performance metrics and node mobility. In order to improve the network mobility management performance, a mobility management scheme is proposed, where the system computes the QoS/QoE and make a decision for mode switching between network-centric to user-centric or vice-versa. The proposed technique show better performance over the traditional cellular network and we compare our results with 4G/Long Term Evolution (LTE), with respect to link utilization, energy consumption, call-to-mobility ratio analysis and system scalability. The performance analysis and comparison demonstrates the superiority of proposed system in terms of QoE parameters as compared to LTE networks.
