According to the human physiological sensor communication needs of transmitting information rapidly and gathering data to the information node conveniently, the mobile's feature of communication fast and use easily is used as the gathering node for forwarding data and applying data. The study on the implementation methods of wireless sensor data interface and the open-frame of the software are carried...
Mobile phones are an underutilized resource for connecting low-power wireless sensor networks (WSNs) to the internet. WSNs typically expend most of their battery power on data transmission. Mobile phones carried by the public could enable a hybrid approach where data makes a low-power short distance hop to phones in the vicinity using Bluetooth or a similar short range protocol, then uses the phones'...
The large scale adoption of mobile phones brings a merging mobile commerce market. Most wireless applications are based on GPRS to provide services in wide areas, while some location based services are based on Bluetooth to enable mobile users to enjoy proximity services. However, very few systems marry the two communication technologies together to provide a more pervasive wireless system with which...
An agent-oriented middleware supporting context-aware mobile eLearning services provision is presented. The middleware architecture developed for a distributed InfoStation-based network established within a University campus is described in detail. A concept for the control and management of service sessions and communications scenarios is also presented.
Content stored on multiple devices owned by people can be accessed and shared via heterogeneous wired and wireless networks. Wireless networks frequently suffer link disconnections, an inherent feature in these types of dynamic environments. These link disconnections occur due to user mobility and wireless characteristics and result in reduced content accessibility to users. This paper presents a...
A software system architecture for context-aware mLearning service execution in an InfoStations environment established within a University Campus is presented. The main user scenarios affecting the context-aware service execution are described. The multi-agent nature of the InfoStationpsilas architecture receives particular attention.
With the rapid growth of user demands, and the limitations of third generation (3G) mobile communication systems, it is expected that fourth generation (4G) mobile systems are likely to reach the consumer market in another 4-5 years. 4G systems are expected to become a platform capable of providing increased bandwidth, higher data rates, and greater interoperability across communication protocols,...
