Mac Protocols for Wdm Networks – Survey and Summary

چکیده
With the proliferation of the world-wide-web (WWW), current local and wide area networks can hardly cope with the huge demand for network bandwidth. As a result, there is a world-wide effort in upgrading current networks with highcapacity fiber-optic links that can potentially deliver Tera-bits/sec bandwidth. The Wavelength-Division-Multiplexing (WDM) is an effective technique for utilizing the large bandwidth of an optical fiber. By allowing multiple simultaneous transmission over a number of channels, WDM has the potential to significantly improve the performance of optical networks. The nodes in the network can transmit and receive messages on any of the available channels by employing one or more tunable transmitter(s) and/or tunable receiver(s). Several topologies have been proposed for WDM networks. Of particular interest to us in this 150 OPTICAL WDM NETWORKS chapter is the single-hop topology where a WDM optical network is configured as a broadcast-and-select network in which all the input nodes are combined using a passive star coupler, and the mixed optical information is broadcast to all destinations. To unleash the potential of single-hop WDM passive star networks, effective medium access control (MAC) protocols are needed to efficiently allocate and coordinate the system resources. In this chapter, we present a comprehensive survey of state-the-art MAC protocols for WDM networks so as to give the reader an overview of the research efforts conducted in this area for the past decade. In addition, it can serve as a starting point for further investigation into ways of coping with the current and the anticipated explosion of multimedia information transfer.

Multi-channel Medium Access Control Protocols for Wireless Sensor Networks: A Survey
Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...

All-optical networks that employ wavelength division multiplexing (WDM) are an attractive architecture for future high-speed networks. Through WDM, multiple channels are created on a single fiber, and an aggregate network bandwidth far greater than the peak electronic processing speed can be realized.

متن کاملModelling of multimedia MAC protocols on WDM optical networks
Conventional Medium Access Control (MAC) protocols perform quite well for the traffic types they have been designed for, but poorly for other traffic streams with different characteristics. But, the emerging multimedia applications require that the MAC protocol should perform equally well for all types of traffic characteristics. In this paper, we propose an integrated MAC protocol (herein term...
