Admission control algorithm for visible light communication random access network under delay and jitter constraints

Abstract

Abstract This paper proposes a random access network admission control algorithm under delay and jitter constraints to efficiently guarantee the quality of service of a visible light communication system. The multi-packet reception technology is considered to enhance network service, and the interrupted Bernoulli process is used to model the arrival process of packets. The queuing model of the system is constructed from the perspective of a single transmission link, and this paper derives the probability of successful transmission for the terminals. The delay and jitter performance are evaluated according to the state transition matrix and Little’s law. The article set up the optimization problem with the goal of maximizing the throughput and the constraint of transmission probability. To solve the optimization problem better, we improve the tunicate swarm algorithm. Moreover, an admission control algorithm is designed under delay and jitter constraints. Simulation results demonstrate the influence of different parameters on the algorithm.
