Healthcare systems integration using Real Time Publish Subscribe (RTPS) middleware

Most of the distributed systems are heterogeneous by nature, where each device is running on different architecture, platform, and operating system. This heterogeneity significantly affects the system communication performance in terms of throughput and delay. In real-time applications, such as healthcare, military, and radar systems, a slight delay can cause a lot of troubles. Thus, the time factor is very important for those applications where the human life or a lot of investment is concerned. Recently, the Real-Time Publish Subscribe (RTPS) middleware has become one of the effective solutions for the real-time distributed systems problems, due to its proved scalability, reliability, flexibility, and rich set of quality of service policies. In this paper, we develop a real-time architecture for porting the RTPS middleware functions into the healthcare systems. Furthermore, we extensively evaluate the developed system over wired and wireless channels in terms of throughput and delay.
