Abstract

This paper proposes a bandwidth-efficient admission control mechanism for EDF-scheduled factory communication cells, which addresses the two main issues of industrial communication, i.e., reliability, which is affected by the intrinsic error-prone and non-deterministic behaviour of such networks, and timeliness, which depends on the transmission scheduling policy adopted. In our model, each real-time flow is associated a target success rate, which is the minimum fraction of messages that have to be delivered correctly and on time, and the methodology to calculate the feasibility of a flow set is provided, which takes explicitly into account message loss and retransmissions according to known statistics of the wireless link. Analytical results are then compared with simulation results to assess the effectiveness of the proposed approach.
