The evolution in mobile messaging and mobile devices has made it possible to provide multimedia rich messaging capabilities to personal digital assistants (PDAs). The need for this arises simply because mobile service providers want to provide an enhanced messaging experience to the user. It also opens up new avenues for business, such as a shopping mall scenario. This chapter discusses the development of a multimedia messaging client for a PDA and a kiosk providing multimedia messages composition, search, share, and sending capabilities. This chapter also discusses the various messaging technologies, enabling wireless technologies, and the peer-to-peer model. The peer-to-peer technology used was Jxta, an XML-based and language agnostic peer-to-peer platform specification from Sun Microsystems. The peers (PDA client and the kiosk) were implemented using the application programming interfaces provided by the Personal Java reference implementation and the Jxta platform’s Personal Java port.

Impossible Task

With the rapid development of mobile devices and wireless technologies, mobile social networks become increasingly available. People can implement many applications on the basis of mobile social networks. Secure computation, like exchanging information and file sharing, is one of such applications. Fairness in secure computation, which means that either all parties implement the application or none of them does, is deemed as an impossible task in traditional secure computation without mobile social networks. Here we regard the applications in mobile social networks as specific functions and stress on the achievement of fairness on these functions within mobile social networks in the presence of two rational parties. Rational parties value their utilities when they participate in secure computation protocol in mobile social networks. Therefore, we introduce reputation derived from mobile social networks into the utility definition such that rational parties have incentives to implement the applications for a higher utility. To the best of our knowledge, the protocol is the first fair secure computation in mobile social networks. Furthermore, it finishes within constant rounds and allows both parties to know the terminal round.

Different types of planar broadband slow-wave systems are used for designing microwave devices. The papers published by Lithuanian scientists analyze and investigate the models of helical and meander slow-wave systems. The article carefully examines the applications of meander slow-wave systems and presents the areas where similar systems, e.g. mobile devices, RFID, wireless technologies are used and reviewed nowadays. The paper also focuses on the examples of the papers discussing antennas, filters and couplers that contain designed and fabricated meander slow-wave systems.

Lietuvos mokslininkų darbuose nagrinėjami spiralinių ir meandrinių lėtinimo sistemų modeliai, tiriamos jų savybės. Darbe aptariamos meandrinių lėtinimo sistemų taikymo sritys. Apžvelgiamos mobiliųjų įrenginių, radijo dažnio identifikavimo, belaidžio ryšio technologijų sritys, kuriose tokios sistemos yra dažniausiai taikomos. Pateikiami darbų, kuriuose taikant meandrines lėtinimo sistemas projektuojamos bei gaminamos antenos, filtrai ir šakotuvai, pavyzdžiai.

mHealth is a very attractive field for mobile applications developers, but it also involves new challenges that developers of programs intended for standard desktops do not usually face. Hence, the first part of this chapter is devoted to survey the development platforms and languages utilized to develop the associated applications of the mHealth system. mHealth is a communications system that consists of mobile devices for collecting and delivering clinical health data to practitioners, researchers and patients. It is also a tool used in the real-time monitoring of patient vital signs, and direct provision of care. Therefore, the second part of this chapter will focuses on the survey of wireless technologies envisioned for use in the mHealth system.

Future Work

The continuous evolution of wireless technologies has made them ideal for use in many different applications, including user positioning. Until now, user positioning applications were focused mainly on providing users with exact location information. This makes them computational heavy while often demanding specialized software and hardware from mobile devices. In this chapter, we present a new user positioning application. The application is intended for use with m-commerce by sending informative and advertising messages to the users after locating their position indoors. The application is based exclusively on Bluetooth. The positioning method we use, while efficient, is nevertheless simple. The m-commerce based messages can be received without additional software or hardware installed. After discussing the available technologies and methods for implementing indoor user positioning applications, we shall focus on implementation issues, as well as the evaluation of our application after testing it. Finally, conclusions are extracted and future work is proposed.

Bluetooth (2001) is one of the low-bandwidth, energy-efficient wireless technologies designed for mobile devices. As the technology spreads widely in various applications, more and more services and functions are brought to the front, so different types of devices may be equipped with the Bluetooth module and appear in the same area. However, when nodes for different services come together, the need for forming a network comes out.
