A User Prioritisation Algorithm for Horizontal Handover in Dense WLANs

Abstract

This paper proposes an algorithm that enhances horizontal handover (HO) in dense wireless local area networks (WLANs), which is implemented in a software-defined wireless networking (SDWN)-based architecture. The algorithm considers the concept of user prioritisation, classifying the WLAN stations (STAs) into two categories representing high and low priorities respectively, and always attempts to guarantee the best quality of experience (QoE) to the high priority users. The architecture that implements the algorithm leverages the flexibility, programmability, and centralised nature of SDWN to efficiently manage the HO process. Moreover, the paper presents a performance evaluation campaign that demonstrates significant achievements against a state-of-the-art solution in terms of the provided QoE, throughput and delay. Finally, we discuss the importance of considering user prioritisation in a HO algorithm for dense WLANs.

A Review on Deploying Blockchain Technology for Network Mobility Management

“…In this case, the IP address is a constant, as the network interfacing module does not change. For software-defined wireless networking architecture having dense wireless local area networks, an algorithm for user prioritization, classifying stations into two priority levels has been effective in guaranteeing quality of service to users by enhancing horizontal handover [41]. A utility function considering signal to noise proportion network burden is formulated for HoH decision in automobileto-automobile communication reducing ping-pong ramification and enriching throughput by picking network having lower burden [42].…”
