Mobile caching-enabled small-cells for delay-tolerant e-Health apps

Abstract

With the wide adoption of Internet of Things (IoT) and specifically e-Health applications, the nature of mobile applications, the increased traffic and the increasing number of connected devices are changing the requirements of wireless mobile networking. Addressing such foreseen increase in number of connected mobile devices, our work proposes a new trend of on-demand mobile small-cells with caching capabilities for e-Health applications. The solution targets delay-tolerant monitoring e-Health applications, with optional ultra-low latency communications for emergencies. The proposed networking architecture supports user mobile devices acting as small-cells with caching capabilities, for later transmission, when efficient high data rate communication conditions exist. The solution supports immediate high data-rate low-latency transmission for emergency situations. The proposed system enhances the performance of cellular networks, by saving on valuable scarce bandwidth and radio resources, while decreasing interference. Self-organizing networking is used for the further optimization of the network performance. The paper discusses performance gains resulting from mobile small cell deployment.
