In this paper we propose a fully distributed storage system for everyday hand-held mobile devices, e.g., smartphones and tablets, that follows a best effort approach to ensure data persistence and availability even in the presence of churn (i.e., the ...

In this paper we propose VANESS, a naming service that supports user-to-user communication on mobile devices within a heterogeneous scenario comprising typical Internet Service providers and ad-hoc networks formed by vehicles and roadside units, VANETs. ...

The development of reactive, context aware mobile applications can be a complex task. EveWorks is an engine that provides event detection capabilities to other applications in mobile platforms, interfacing with them through expressions written in EveXL, ...

In this paper we present an interaction mechanism that allows TV viewers to synchronise their second screen applications in a simple and effortless way. This mechanism relies on the user feedback to deliver in-sync second screen events, and was designed ...

Mobile devices equipped with indoor positioning capabilities

can access a broad range of dierent Location-Based

Services (LBS). There are advanced LBS applications that

use the user's location and preferences in order to give the

most precise answer to ...

Mobile devices, including off-the-shelf smartphones, are being used as data gateways for nearby sensors in end-to-end integration of monitoring solutions, mostly based in the Android OS. In this paper, we present LIMBus, a lightweight monitoring system ...

To improve the performance of Massively Multiplayer Online Games (MMOGs) in mobile networks, we explore the potential benefits of an edge-assisted deployment model: part of the MMOG backend service executes closer to the end user at the edge of the LTE ...

Towards the realization of smart building applications, buildings are increasingly instrumented with diverse sensors and actuators. These sensors generate large volumes of data which can be analyzed for optimizing building operations. Many building ...

The rapidly increasing computing power, available storage and communication capabilities of mobile devices makes it possible to start processing and storing data locally, rather than offloading it to remote servers; allowing scenarios of mobile clouds ...

The current capabilities of mobile phones in terms of communication, processing and storage, enables its use to form autonomous networks of devices that can be used in case of collapse or inexistent support from a communication infrastructure. In this ...

In this paper, we present an asynchronous, accurate, and real-time distance measurement method using chirp signals, which is capable of accurately locating and tracking, thus forming an ad-hoc network among smartphones in an indoor (e.g., smart meeting ...

We present a Cyber-Physical System for distributed monitoring of first response teams. To cope with different setups, different sensors and computing devices, found in the evolution of the VitalResponder project, we adopted a message brokering pattern ...

Mobile ad hoc networks (MANETs) have a number of features that make the provisioning of Quality of Services (QoS) particularly challenging. One of the most challenging issues is how to discover more reliable paths for high priority traffic delivery in a ...

Fall detection is a classical use case for mobile phone sensing.

Nonetheless, no open dataset exists that could be used to train, test

and compare fall detection algorithms. We present a dataset for mobile

phone sensing-based fall detection. The ...

Falls are among the leading causes of hospitalization for the elderly and illness individuals. Considering that the elderly often live alone and receive only irregular visits, it is essential to develop such a system that can effectively detect a fall ...

A context-aware system uses context to provide relevant information

and services to the user, where relevancy depends on the user’s

situation. This relevant information could include a wide range of

heterogeneous content. Many existing context-aware ...

We propose a simple and effective yet novel method designed for iOS smartphones that autonomously tracks its user's destinations and sparse trajectory. The smartphone application manages to do that 24/7 unobtrusively in the background and without ...

The Internet of Things (IoT) paradigm aims to interconnect a variety of heterogeneous Smart Objects (SO) using energy-efficient methodologies and standard communication protocols. A majority of consumer devices sold today come equipped with wireless LAN ...

As app based paradigms are becoming popular, millions of

apps are developed from many domains including energy,

health, security, and entertainment. The US FDA expects

that there will be 500 million smart phone users downloading

healthcare related apps ...

Online route planning services compute routes from any given location to a desired destination address. Unlike offline implementations, they do so in a traffic-aware fashion by taking into consideration up-to-date map data and real-time traffic ...

The growing ubiquity of personal connected devices -- each with a number of sensors -- has created the opportunity for a wide range of crowd-sourced services. Although the programming required for offering new services can be significant if done from ...

Accurate estimation of localized occupancy related informa-

tion in real time enables a broad range of intelligent smart

environment applications. A large number of studies using

heterogeneous sensor arrays reflect the myriad requirements

of various ...

In-vehicle connectivity has experienced a big expansion in recent years; car manufacturers are very active in this sense, and are proposing OBU oriented solutions. This effort is justified by the user demands for always-on connectivity. However, ...

Location Based Services are providing one of the fastest growing market segments today. While the most common technique for location determination is GPS, several alternative approaches have been proposed for Wi-Fi environments, based on time of flight, ...

Human activity recognition using multi-modal sensing technologies to automatically collect and classify daily activities has become an active field of research. Given the proliferation of smart and wearable devices and their greater acceptance in human ...

An activity recognition system essentially processes raw sensor data and maps them into latent activity classes. Most of the previous systems are built with supervised learning techniques and pre-defined data sources, and result in static models. ...
