Performance evaluation of the Consumer Electronic Bus

Abstract

The results of a simulation study undertaken to evaluate the performance of the Consumer Electronic Bus (CEBus) under various traffic patterns and especially under large traffic generated by high-priority nodes are reported. The CEBus is based on the ISO/OSI model of layered architecture. The simulation results have shown that, when the throughput of the network is small (30%), the delay is bounded for all messages of all priorities. As the throughput of the network increases to more than 70% due to an increasing number of high-priority messages, the lower-priority messages get queued at their nodes. It is also shown that the delay can be bounded, when needed, by assigning high-priority status to nodes generating messages with urgent communications and lower-priority status to nodes sensing messages which do not require immediate response.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
