Abstract

It has been shown analytically [1],[2] that significant performance improvements as compared to existing technologies (e.g., IEEE 802.11) can be achieved in random access wireless networks. In [3] we proposed a fully distributed channel access paradigm based on the opportunistic communication principal called the Channel MAC paradigm suitable for distributed wireless networks such as ad hoc networks. In this paper, we analytically derive the throughput of the Channel MAC. It provides a throughput-limit on the channel-based MAC mechanism in shared multiple access environments without collisions or capturing effects. Both simulation and analytical results reveal possible performance improvement over existing techniques.
