The ability to note down small pieces of information, quickly and ubiquitously, can be useful. This paper proposes a system called PhonePoint Pen that uses the in-built accelerometer in mobile phones to recognize human writing. By holding the phone like ...

Mobile phones are becoming a convergent platform for sensing, computation, and communication. This paper envisions "VUPoints", a collaborative sensing and video-recording system that takes advantage of this convergence. Ideally, when multiple phones in ...

Counterfeit and expired pharmaceuticals are a significant problem in the developing world, constituting up to 80% of stock on pharmacy shelves. This is due both to poor existing controls and to lack of supporting infrastructure on which to build such ...

SMS-based web search is different from traditional web search in that the final response to a search query is limited to a very small number of bytes (typically 1-2 SMS messages, 140 bytes each). SMS-based web search is also a non-interactive search ...

In this paper a practical offline payment system based on digital vouchers using Near Field Communication (NFC) in mobile phones is presented. This work was performed within the scope of the IBBT NFC-Voucher project. The goal of the project is to assess ...

Modern mobile phones possess three types of capabilities: computing, communication, and sensing. While these capabilities enable a variety of novel applications, they also raise serious privacy concerns. We explore the vulnerability where attackers ...

People increasingly generate content on their mobile devices and upload it to third-party services such as Facebook and Google Latitude for sharing and backup purposes. Although these services are convenient and useful, their use has important privacy ...

We propose a novel approach to Pocket Switched Networks (PSNs)using a specialised declarative language called 'D3N'. A PSN is a recently devised type of communication based on physical proximity, where people encounter each other and their devices ...

Energy is the critical limiting resource to mobile computing devices. Correspondingly, an operating system must track, provision, and ration how applications consume energy. The emergence of third-party application stores and marketplaces makes this ...

Current mobile devices embrace a wide range of functionalities including high speed network support, hardware accelerated 3D graphics, and multimedia capabilities. These capabilities have boosted the interest for enabling multiplayer online games (MOG) ...

We present SenseLess, a system that leverages the different energy consumption characteristics of sensors to maximise battery life in mobile-sensing applications. We use the less expensive sensors more often, thereby enabling us to use the more ...

For most mobile networks, providers need the current position of their users to provide efficient service. The resulting motion data is not only an invaluable source for analyzing traffic or flow patterns, but also for tracking an individual's ...

Service oriented access in a multi-application, multi-access network environment poses interesting research challenges. One of these challenges refers to cross-layer interoperability among technologies. In this poster, we introduce a knowledge base (KB) ...

For wireless mobile Internet users the length of the battery life is one of the most important performance factors. The energy efficiency of the data transmission over radio is a key component affecting the battery lifetime. This paper investigates WLAN ...

In this paper we describe Efficient Lightweight Mobile Records (ELMR), a system that provides a practical protocol for accessing and updating database records remotely from low-end mobile devices using the 140-byte SMS channel.

Mobile thin client computing is an enabler for the execution of demanding applications from mobile handhelds. In thin client computing, the application is executed on remote servers and the mobile handheld only has to display the graphical updates and ...

We present mango, a low-cost and highly scalable content-delivery service for mobile phones. The service is targeted at emerging countries such as India where users are highly price sensitive, and there is considerable demand for rich media content. ...

We describe a new model for studying intermittently connected mobile networks, based on Markovian random temporal graphs, that captures the influence of message size, maximum tolerated delay and link stability on the delivery ratio.

This demo illustrates the benefits of BitHoc, a standalone protocol for content sharing among spontaneous communities of mobile handhelds using wireless multi-hop connections. BitHoc is a Trackerless BitTorrent-like application adapted to mobile ...

In this paper, we describe the opportunistic localization, which enables localization services that works seamlessly in heterogeneous environments including indoors as oppose to GPS based outdoor-only systems.
