A new real-time ethernet MAC protocol for time-critical applications

The authors propose a new persistent transmission-based real-time Ethernet MAC protocol that provides a predictable upper bound for the delivery delay of real-time frames. Moreover, it is compatible with the protocol used by the existing Ethernet controllers for conventional datagram traffic and thus standard Ethernet stations can be used in the system without any modification. The paper describes the protocol in detail and analyses the maximum delivery delay for real-time traffic and the efficiency of the channel.

Robust filtering for a class of local strongly coupled systems

This paper addresses the H∞ filtering problem for a kind of local strongly coupled systems. We introduce a local strongly coupled system with communication between the nodes. Applying the H∞ filter design procedures to such systems is difficult because of intermittent communication. By using the stochastic theory, we present the H∞ filtering problem in terms of the full system dynamics. The numerical simulations show the effectiveness of the proposed filtering method.
