The expected (not worst-case) throughput of the Ethernet protocol

The Ethernet protocol is analyzed using a space-time model in which the occurrence of a collision is determined not only by frame arrival times but also by locations of nodes. The space-time model is described, and the expected throughput of the Ethernet protocol is derived assuming that frames arrive by a Poisson process. Numerical results show that the expected throughput can be significantly higher than earlier time-domain results when the spatial dimension a>0.01. This result is attributed to, among other factors, a significant reduction of the vulnerable area.<>
