On real-time requirements in constrained wireless networks for mobile health

Abstract

This paper analyzes the requirements of mobile health applications concerning real-time criteria and describes the current state of real-time capabilities on constrained devices and low-power networks. Based on this analysis we observe that for these applications real-time capabilities are not only required per system, but also for the entire distributed system. Furthermore, we describe which technologies are available for the network stack, the software platform, and the hardware in order to fulfill these requirements. From the requirements on the network stack, following a top-down approach, we derive hardware prerequisites. We then conduct measurements on typical IoT hardware and operating system. We conclude that it is feasible to fulfill the identified prerequisites.
