Recent trends on mobile computing and future networks

With the development of IT convergence technologies to improve quality of life, users can now more easily access useful information. A convergence system represents an environment that is able to provide personal services by configuring various devices and sensors based on both wire and wireless networks. Further, diverse and far-reaching information is being produced fast and distributed instantly in digitized format. Studies on mobile computing are continuously presenting more efficient ways of delivering information to more users. Mobile computing is a technology that provides a service automatically based on perceived situational information in personal and ubiquitous environments. Ubiquitous computing is characterized by users who are focused on a virtual space established by computers and networks. However, mobile computing groups of computers work through various sensors that exist in the real world. Users are able to receive various personal services using many different types of mobile computing resources within an internal/external space, without limitations in time or space [1, 2]. Previously, users had to convey their intentions using standard input devices and obtain the results on an output device. On the contrary, in a distributed and mobile computing environment, lifelog, sensors, big data, and computing resources are ubiquitous in a user’s everyday life. To provide personal services according to various lifestyles, these computing resources should be aware of a user’s intentions and the surrounding environment, as well as provide optimal services [3, 4].
