On the Use of Clustering Algorithms for Message Scheduling in WDM Star Networks

Free registration required

Executive Summary

Scheduling algorithms in Wavelength Division Multiplexing (WDM) single-hop networks aim at producing an effective schedule in order to improve the networks' performance. Apart from channel assignment, the message sequencing is an important issue that has to be addressed when designing Media Access Control (MAC) protocols for WDM networks. Up until now, popular approaches have not extensively addressed the order in which the messages are scheduled even though the messages' service order can considerably contribute to the advance of network performance. This paper introduces a new approach to the design of message scheduling algorithms for WDM star networks, which is based on the use of clustering techniques.
