The Performance Evaluation of Embedded Communication Networks

Some Embedded systems involve multiple processors connected by a communication medium. These processors communicate with each other exchanging short messages using some message based communication protocols such as Controller Area Network (CAN), SAE J1939 etc. With the induction of new features inside such networks, the number of messages will increase. The increase of messages may affect the network performance for a given network characteristics. Performance evaluation of a message based networks is therefore desired with increasing message load. This paper presents the performance evaluation of message based embedded communication networks. Several parameters have been estimated as function of number of messages.
