Data centric communication using the wireless Control Area Networks
Bechir BenGouissem, Sofiene Dridi · 2006
For large-scale distributed systems, Data centric communication based on the publish/subscribe paradigm plays a key role on traffic volume control. More data filtering efficient and adaptive to different traffic conditions bring some solutions at the high layers of the communication model. DDS and OPC-DX are the most adopted solutions, in real-time data centric sensor networks. Some Real-time transport and MAC protocols are proposed in the literature to support these types of networks. Existing MAC protocols, scheduling based, collision free, contention based or hybrid schemes focus more on optimizing system throughput and do not adequately consider the requirements of sensor networks. The key challenge remains to provide predictable delay and/or prioritization guarantees while minimizing overhead packets and energy consumption. It is widely known that control area networks (CAN) are used in real-time, distributed and parallel processing. In this paper we propose to use of the WCAN protocol in data centric communications model to manage concurrency.
