A few years ago, the IT industry forecast that consumer demand for data would surpass that of the voice market. At the time, few could conceptualize such an outlook. These days the data market is at least 70% larger than the mobile market, and still growing. Mobile technology has advanced in leaps and bounds over recent years, such that experts predict that, within the next few years, mobile computing will be strictly bound to cloud computing. Mobile cloud computing is set to impact and transform the mobile communication landscape and the whole computing infrastructure. Computing offloading, for example, is one of the main features of mobile computing to improve the battery life of mobile devices and to improve the performance of applications. However, there are many associated issues to solve, including efficient and dynamic offloading in a variable environment.

During any social interaction, nonverbal social signals convey just as much information as the conversation itself. While transmitting and analysing conversation is quite a common task for machines, the transmission and analysis of social signals is not. The convergence of cloud computing and mobile computing leads to a situation where insight into social systems is possible, thus paving the way for exciting new applications.

The ability to pinpoint a terminal’s position is useful for many applications of mobile computing and for network optimization (eg handovers, tariffs, resource management). A range of techniques are available to obtain a terminal’s position [1]. GPS, for example, is used externally to the network and achieves good accuracy outdoors, with the trade off of increased energy consumption. Communication devices, however, are frequently used indoors, connecting to private networks, such as WLAN. Since GPS is inaccurate indoors owing to signal blockage and multipath errors, further research on indoors localization through communication networks is required. Mobile computing is linked to indoors positioning in applications such as: aged care, remote health control and security of buildings such as hospitals.

The Android operating system is a burgeoning platform for deploying mobile applications to users, with more than 550,000 activations per day and an approximate 75% share of the global smartphone market that eclipses the once-dominant Apple iOS [1,3]. This trend is expected to continue, considering that Android's liberal licensing structure, open development environment, wide adoption across multiple hardware manufacturers and carriers, and modern end-user experience make it an attractive platform for both civilian and military use.

Data mining is emerging as a promising topic in mobile computing environments. We have defined a distributed architecture in which mobile devices cooperate in a peer-to-peer style to perform a data mining process, tackling the problem of energy capacity shortage by distributing the energy consumption among the available devices. An energy-aware (EA) scheduling strategy assigns data mining tasks over a network of mobile devices optimizing energy usage. The main design principle is to find a task allocation that prolongs the network residual life by balancing the energy load among the devices.

We present our wireless solution to device synchronization, control and real-time feedback for small and light-weight Inertial Measurement Units, (IMUs). The controller is implemented on a smartphone. We base a custom application layer on the protocol layer implemented on a low-power radio chip by ANT+TM. Our system is capable of synchronized (< 15 μsec) control of an arbitrary number of sensors (ETHOS), streaming data for real-time visualization and it reduces power consumption compared to other approaches.

The spectacular growth of mobile internet on smartphones and tablet computers has boosted the demand for fast wireless networks. By 2015, mobile data exchange is expected to be 26 times larger than it was in 2010 [1]. In the first six months of 2012, the mobile internet traffic volume in the Netherlands was 21% higher than that recorded in the last six months of 2011 [2]. A highly promising means to meet the increasing demand is to take advantage of the fact that many geographical areas are covered by a multitude of overlapping networks. This phenomenon is referred to as concurrent access (CA). CWI and technology company Thales Nederland B.V. have developed new methods to make efficient use of the possibilities of CA by developing and implementing smart algorithms to split traffic over the multitude of wireless access networks.

Mobile systems are becoming ubiquitous, which, in combination with wide-range service-oriented architectures, offers enormous potential for a range of uses. In this context, we have developed the CoMobility platform, a system designed to integrate carpooling and the use of public transport networks, with the goal of reducing energy consumption and CO2 emissions. CoMobility defines a service-oriented platform to help mobile users plan their use of transport, including sharing, with the purpose of saving both energy and money.

Quality of Service Information System (QoSIS) focuses on measurement-based performance evaluation of wireless access networks provided by diverse mobile network operators in diverse locations and times. We have developed an Android OS mobile application that uses measurement data provided by real mobile users living in the Geneva area to predict the networks' expected performance. Measurement data, and therefore predictions, are available for Swiss operators: Swisscom, Sunrise, Orange CH, as well as French operators: SFR, Bouygtel and Virgin.

Pervasive networking devices, including mobile devices, generate an environment saturated by heterogeneous hardware and software resources. Novel mobile computing paradigms allow this environment to be organized and orchestrated. “Opportunistic computing” is a new approach that allows applications to take advantage of self-organizing services built, in a dynamic way, out of the mobile resources that are available in pervasive environments.

The rapid emergence of mobile devices, such as TabletPC and smartphones, equipped with a rich array of sensors, enables a new means of acquiring sensor data, known as crowd-sensing. Crowd-sensing is currently receiving a lot of attention, not only from industry but also from various research communities interested in collecting a new class of data over a much larger population than was previously possible.

Wi-Fi technology, available in the vast majority of mobile phones, tablets, laptops and other computing devices that we use in our daily lives, has enabled widespread use of new applications and services. This technology, however, has a number of issues related to privacy loss, exacerbated by its ubiquity. Our research shows how the information freely transmitted by the Wi-Fi protocol can be used to identify links between people, ie whether they are family, friends, colleagues etc.
