On the Throughput Comparisons of MAC Protocols in Multi-Hop Wireless Networks

Free registration required

Executive Summary

The authors revisit the use of throughput metrics in studying Medium Access Control (MAC) protocols in static multi-hop wireless networks. To complement existing single-hop and multihop throughput notions, they first propose a unified normalized throughput expression. Since current multi-hop metrics do not give much intuition on how close a MAC protocol's throughput performance is to the best achievable for a given network topology, they present a new variant that benchmarks against the maximum achievable throughput. It can be characterized by the product of the number of maximum successful simultaneous transmissions smax under saturated traffic conditions, and link rate R.
