Mobility of people (users) plays an important role in day-to-day life, and currently these users are overwhelmed by a variety of services. Mobile services belong to an essential segment of modern communication services, and new trends in these consist of smart services, defined as a variety of context-aware services. Additionally, smart mobile devices (smartphones) can fulfil an astonishingly wide range of demands of users and providers. One of the reasons behind mobile development is the ever-growing computing power and communication capabilities of mobile devices. Furthermore, smart mobile devices offer new human-computer interfaces like speech recognition or touchscreens, and employ powerful sensors, such as GNSS receivers, inertial sensors, or new communication platforms. The mentioned supporting technologies enable the provision of a completely new spectrum of context-aware, personalized, and intelligent services and applications. This raises device utilization issues, not only from the communication point of view, but also for device smartness purposes. Smartphones, in fact, are very powerful devices with constantly increasing processing, communication, and sensing capabilities, and very recently a large plethora of proposals have emerged to leverage those capabilities to contribute to the information production process. Smart mobile devices can be used in the health care sector and in the transportation sector, and in addition multimedia services form a very interesting sector.

Because a variety of wireless telecommunication services need position information for real time service operation, almost all modern devices are equipped with GNSS sensor. However, it cannot always be used due to the corresponding received signal strength level being too low or there is no signal present at all. In these cases, alternative positioning solutions are available or can be implemented. These alternative positioning solutions mainly utilize the improving mobile device performance such as increasing processing, communication, and sensing capabilities. A challenging wireless mobile environment impacts on the delivering of these services, as each service is sensitive to the immediate status of the radio channel in different ways, and these needs to be considered in the services design.

Recently, we are witnessing a dynamic cloud computing evolution in nearly all areas of human activities exploiting information technologies. The implementation of solutions based on the idea of cloud services produces new challenges in areas such as management, security, technical solutions, infrastructure modelling, mobile devices support, and many others.

This Special Issue aims to collate original research and review articles with a focus on the research and development of described services areas with smart mobile devices. These include solutions that are directly designed for smart mobile devices covered by wireless networks, and solutions that are not directly designed for such use but have the potential for it.
