Mobility of people (users) plays an important role in day-to-day life. Users are overwhelmed by the variety of services. Mobile services belong to essential segment of modern communication services. New trends in mobile services consist in smart services, that is, a variety of context-aware services. Additionally, smart mobile devices (smartphones) are able to fulfill an astonishingly wide range of demands of users and providers. One of the reasons behind the 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 touch screens 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 (e.g., home care service) and in the transportation sector (e.g., vehicle telemetry services). In addition, multimedia services form a very interesting sector.

Because a variety of wireless telecommunication services need the position information for real time service operation, almost all modern devices are equipped with GNSS sensor, but it cannot always be used due to the fact that corresponding received signal strength level is too low or signals are not presented. In this case alternative positioning solutions are available or can be implemented. These alternative positioning solutions mainly utilize improving of mobile device performance, for example, increasing processing, communication, and sensing capabilities. A challenging wireless mobile environment impacts on delivering of the services. Each service is sensitive on the immediate status of radio channel in different ways and this need to be taken into account in the services design.

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

This special issue is addressed to researchers and engineers in both academia and industry sectors to exchange ideas, share experiences, and report original works about all aspects of the above-stated philosophy.

We invite investigators to contribute original as well as review articles on research and development of described services areas with smart mobile devices. These include solutions that are directly designed for the smart mobile devices covered by wireless networks and solutions that are not directly designed for such use but have potential for it.

Potential topics include, but are not limited to:

• Context- and location-aware services and applications
• Location technologies supporting smart mobile services
• Location-based services for intelligent transportation systems
• Effect of mobility on mobile computing
• An impact of wireless mobile environment on service delivery investigation
• Personalization, privacy, and security issues of smart mobile services
• Multimedia and integrated mobile services
• Mobile telemedicine and e-health as mobile services
• Mobile services based on cloud computing
