Dynamic Channel Allocation for QoS Provisioning in Visible Light Communication

TL;DR

This paper proposes a dynamic channel reservation scheme for visible light communication that prioritizes high-priority traffic without reducing overall channel utilization, based on real-time call arrival data.

Contribution

It introduces a real-time adaptive channel reservation method for VLC that improves high-priority call handling while maintaining efficient channel use.

Findings

Reduces call blocking probability for high-priority users

Maintains high channel utilization

Adapts reservation based on real-time traffic data

Abstract

In visible light communication (VLC) diverse types of traffic are supported while the number of optical channels is limited. In this paper we propose a dynamic channel reservation scheme for higher priority calls that does not reduce the channel utilization. The number of reserved channels for each traffic class is calculated using real time observation of the call arrival rates of each traffic classes. The numerical results show that the proposed scheme is able to reduce the call blocking probability of the higher priority user within a reasonable range without sacrificing channel utilization.
