Abstract |
It is widely known that Control Area Networks (CAN) are used in real-time, distributed and parallel processing which cover manufacture plants, humanoid robots, networking fields, etc. Where wireless conditions are encountered it is convenient, as we will demonstrate later, to continue the exchange of CAN frames within a baptized Wireless CAN (WCAN). While we define the WCAN, we adopted the RTS/CTS scheme to gain access to the medium in a first step and the exchange of ordinary CAN frames in a second step [1, 2, 3]. The latency time is the most important factor to consider when evaluating a control network. The latency incurred in message delivery has not been a metric to be optimized. So in the second part of this paper, we compute the throughput-latency time couple that would guarantee a maximum throughput and a minimum latency time in the case of wireless communications, precisely in WCAN. This work represents our real contribution by introducing the WCAN concept for the first time, by the correct definition of WCAN frames, by the evaluation of parameters boundaries of WCAN, and by the calculation of the latency time and its coupling to the throughput, according the medium access scheme. |
