Abstract
In this paper, we present a tiny networked mobile platform, termed Tiny-Web-Thing (T-Wing), which allows the sharing of data-intensive content among objects in cyber physical systems. The object includes mobile platforms like a smartphone, and Internet of Things (IoT) platforms for Human-to-Human (H2H), Human-to-Machine (H2M), Machine-to-Human (M2H), and Machine-to-Machine (M2M) communications. T-Wing makes it possible to host rich web content directly on their objects, which nearby objects can access instantaneously. Using a new mechanism that allows the Wi-Fi interface of the object to be turned on purely on-demand, T-Wing achieves very high energy efficiency. We have implemented T-Wing on an embedded board, and present evaluation results from our testbed. From the evaluation result of T-Wing, we compare our system against alternative approaches to implement this functionality using only the cellular or Wi-Fi (but not both), and show that in typical usage, T-Wing consumes less than 15× the energy and is faster by an order of magnitude.
Highlights
The proliferation of mobile platforms has led to an increase in the use of the mobile web-based interactions [1]
Users are willing to pay for mobile data plans, and can browse websites from a mobile platform, wherever they are, just as they would from a general computer system
One critical component underlying T-Wing is a new mechanism that allows mobile platforms to turn on their Wi-Fi interface purely ‘on-demand’, that is, only when the mobile platform is either requesting data from nearby mobile platforms, or serving its content to any nearby mobile platform
Summary
The proliferation of mobile platforms has led to an increase in the use of the mobile web-based interactions [1]. Deployed mobile devices, including many commercial off-the-shelf (COTS). Such as smartphones and IoT devices are generally equipped with two indispensable communication modules: Wi-Fi and a cellular network interface. In contrast to a general computer system, the mobile platform is with the user most of the time. This has led to a new class of applications that allow a user to push content over the Internet from the convenience of his mobile platform. The trend is to make it easier for users to push interesting content to the Internet, and for smart objects to make interactions with mobile platforms of users [5,6]
