Abstract
Emerging sensor-embedded smartphones motivated the mobile Internet of Things research. With the integrated embedded hardware and software sensor components, and mobile network technologies, smartphones are capable of providing various environmental context information via embedded mobile device-hosted Web services (MWS). MWS enhances the capability of various mobile sensing applications such as mobile crowdsensing, real time mobile health monitoring, mobile social network in proximity and so on. Although recent smartphones are quite capable in terms of mobile data transmission speed and computation power, the frequent usage of high performance multi-core mobile CPU and the high speed 3G/4G mobile Internet data transmission will quickly drain the battery power of the mobile device. Although numerous previous researchers have tried to overcome the resource intensive issues in mobile embedded service provisioning domain, most of the efforts were constrained because of the underlying resource intensive technologies. This paper presents a lightweight mobile Web service provisioning framework for mobile sensing which utilises the protocols that were designed for constrained Internet of Things environment. The prototype experimental results show that the proposed framework can provide higher throughput and less resource consumption than the traditional mobile Web service frameworks.
Highlights
The capabilities of recent mobile devices such as smart phones and tablets have been steadily enhanced with faster processing power, larger and higher resolution display screens, greater memory, and enhanced power saving mechanisms
In this paper, we extend ourprevious work [11] towards presenting a lightweight mobile Web service provisioning framework based on integrating a number of lightweight protocols including Constrained Application Protocol (CoAP) [12], Bluetooth Low Energy (BTLE) [13] and Efficient XML Interchange (EXI) [14]
Unlike traditional web servers based on HTTP, our application layer utilizes CoAP that provides a solution with a compact header size, simple, lightweight, RESTful message exchange in between mobile host and clients over constrained network
