Abstract

The predictive p-persistent carrier sense multiple access (p-persistent CSMA) algorithm is studied, using analytical models, simulations, and physical experiments. The algorithm is used for managing access of devices to a shared channel in networked control applications such as the local operating networks (LonWorks). The key to its success is an adjustment of a time window during which ready packets are transmitted. A Markov-chain based analytical model for the algorithm is developed, as well as an OPNET-based simulation of the model. Predictions of the analytical model and simulation are compared to experimental data collected from a network of six SMART I/O ADR112-F units connected though TP/FT-10 channel
