Various legacy and emerging industrial applications require closed-loop control over multiple hops. Existing multi-hop wireless technologies do not completely fulfill the stringent requirements of closed-loop control. This paper proposes a novel wireless solution, termed as GALLOP, for closed-loop control over multi-hop networks. GALLOP adopts a pragmatic approach for tackling the peculiarities of closed-loop control. Key aspects of GALLOP design include control-aware multi-hop scheduling for cyclic information exchange with very low and deterministic latency, cooperative transmissions for very high reliability and low-overhead signaling mechanism for scalable operation in large-scale networks. GALLOP has been specifically designed for control loops closed over the whole multi-hop network with dynamics on the order of few milliseconds. Performance evaluation through hardware implementation on a Bluetooth 5 testbed and system-level simulations demonstrate the viability of GALLOP in providing high-performance connectivity as required by closed-loop control applications.

In this work, we consider hard real-time applications scheduled upon heterogeneous multiprocessor platforms. The originality of this study is to consider multi-mode real-time applications (software aspects) and reconfigurable-heterogeneous hardware platforms (composed of CPUs, GPUs, FPGAs...). Our approach is based on a multi-mode protocol, for mode-dependent tasks upon reconfigurable hardware. The goal is to handle predictable switches between different task sets and different hardware settings. The novelty here is the dynamic hardware and software reconfigurability. First, we propose a formal model of the applications and reconfigurable hardware platforms. We then propose and prove correct a mode change protocol. We propose in particular a validity test for the verification of the timing constraints of the application --- including the time allowed to complete a mode change. We also perform a complete evaluation. We study the theoretical complexity of the protocol, use a simulation to evaluate the efficiency of our solution, and finally propose a competitive analysis of our protocol to prove that it is 2-competitive.
