Aura: An IoT Based Cloud Computing Infrastructure for Localized Mobile Computation

Abstract

Many applications require localized computation in order to ensure better performance, security, and lower costs. In recent years, the emergence of Internet-ofThings (IoT) devices has caused a paradigm shift in computing and communication. IoT devices are making the physical environment and infrastructures smarter, bringing pervasive computing to the mainstream. With billions of such devices slated to be deployed in the next ve years, we have the opportunity to utilize these devices fi in converting our physical environment into interactive, smart, and intelligent computing infrastructures. This paper present an Aura – a highly localized IoT based cloud computing model. Aura allows clients to create ad hoc clouds using the IoT and other computing devices in the nearby physical environment, while providing the exibility of cloud computing. Aura provides localized computation capability fromfl untapped computing resources. Computations done on Aura are highly exible, fl giving clients full control to start, stop, migrate, and restart computations in nearby devices as the clients move between different physical locations. To demonstrate the feasibility of Aura, we have ported a lightweight version of Map Reduce to run on IoT devices.
