Wireless Medium Access Control Protocol For CAN

In this paper we study the wireless communication extension for the Controller Area Network (CAN) protocol to suit industrial applications. Two different network topologies and medium access methods have been considered. The remote frame and the prioritised frame medium access control (MAC) methods are proposed for the centralised and distributed wireless CAN based network. The performance of these protocols is evaluated by simulating the protocols in the wireless CAN network. The “SAE Benchmark " is used as the workload to illustrate the industrial applications of CAN based system. This paper discusses the applicability of the proposed wireless MAC protocols and confirms its usefulness for real-time communication base on the b nchmark. Control Area Network (CAN) is an advanced serial communication protocol which can supports efficiently distributed real-time computer control system with a very high level of data integrity. To facilitate data transfer between mobile terminals and stationary terminals in a distribute
