Abstract
Increasing digitalisation of society due to technical advancement has increased the appearance and size of cyber- physical systems. These systems require real-time reliable control, which comes with its challenges. These systems need reliable communication despite the presence of attacks or faulty processes and bad connections, which can disrupt the timeliness and correctness of these applications. Furthermore the scale of these systems are becoming increasingly larger as such the cost of connecting all processes that make up these systems become very high. This paper addresses the issues of reliable communication in these conditions while allowing for networks to be partially connected. We show that the protocol discussed can meet real- time requirements of these systems even under conditions of bad connections and low network connectivity.
