MiniCloud

Abstract

The number of heterogeneous Internet-of-Things (IoT) objects continues to grow, estimated to pass 50 billion by 2020. IoT objects are smart heterogeneous devices that are required to communicate and exchange data autonomously. For example, in a smart home, different devices such as sensors, cameras, actuators and control systems need to routinely share information and make decisions. The main challenge however is that there is generally no common platform for data storage and sharing between heterogeneous devices --- this paper addresses this problem. We propose a light storage and query service called MiniCloud that enables seamless communication between heterogeneous devices at a local scale. MiniCloud possesses the following properties: (1) acts as a live-storage hub that augments local data in real-time; (2) offers a set of APIs for any connection type with callback capabilities and dynamic queries; and (3) is portable with code size of only 78 kB which can be readily accommodated in most resource-constrained devices.
