Understanding Channel Saturation in Multi-Channel MAC Systems

Free registration required

Executive Summary

Multi-channel MAC systems offer high capacity, a prerequisite for the next generation networks. High capacity will ensure that the requirements of delay sensitive and time bounded flows are met. For high capacity to be a reality, a good channel selection, coordination scheme and network connectivity is required. A common control channel approach addresses the connectivity challenge. However, it is perceived to be a bottleneck as it saturates degrading data channels. The saturation problem is not widely studied. This paper investigates saturation levels of both control and data channels. The length and channel occupancy of control and data channels are explored.
