Abstract
Purpose
The purpose of this paper is to propose a scheduling method called the “Hierarchical Asynchronous Harmonic Broadcasting (H‐AHB)” method, to reduce the waiting time for heterogeneous clients.
Design/methodology/approach
The authors analyze and evaluate the performance of the proposed H‐AHB method.
Findings
It was confirmed that the proposed method gives shorter average waiting time than the conventional methods.
Research limitations/implications
A future direction of this study will involve making a scheduling method where the server broadcasts multiple videos.
Practical implications
In general broadcasting systems, the server broadcasts the same data repetitively and clients wait until the first portion of the data is broadcast. Although the server can deliver the data to many clients concurrently, clients have to wait until their desired data are broadcast.
Originality/value
The H‐AHB method further reduces waiting time by scheduling an effective broadcast that considers the number of clients' available channels.
