Throughput Models of CSMA Network with Stations Uniformly Distributed along the Bus

The distribution of station locations in a CSMA network can have significant effect on network throughput. In this paper, we develop an analytic model for unslotted, non-persistent CSMA bus network where the stations are uniformly distributed along the bus. We derive a closod form expression for throughput approximation, and discuss the fairness of CSMA protocol using the bus topology. Analytic and simulation results are presented and compared.
