Development of embedded gateway for Wireless Sensor Network and Internet Protocol interoperability

Wireless Sensor Network (WSN) usage for buildings and household has been increasingly popular because it offers various benefits, such as home automation and home surveillance. Therefore, in order to increase WSN usage flexibility, remote controlling which enables remote administration is required. In fact, generally WSN is controlled by a coordinator (sink node) that is located closely to the WSN area itself. By utilizing iterative development, which is suitable for main and supporting application development with several iterations, this research proposes WSN and Internet Protocol (IP) interoperability that enables remote controlling and managing through Internet. Eventually, this research creates a web-based application which will be implemented to a wireless Access Point (AP) for easier WSN remote controlling. Furthermore, it could accommodate WSN from various vendors by software only solution.

Mobile tourism services model: A contextual tourism experience using mobile services

Tourism is closely connected with mobile activities. People go the tourism attractions by doing mobile within city or even country. As a tourist, mobility means put some risk for the convenience of sightseeing. For example, when the visitor visits the attractions might feel uncomfortable because crowd of people, closed attractions, or meaningless unguided tour. This paper describes an alternative approach to improve the tourism experience through mobile software technology. The research proposes a model namely mobile tourism service model. Mobile tourism service model is designed to fulfill the gap between the tourism experience and the contextual of the attractions. As a benefit, mobile tourism services model will guide a content developer to create mobile application that improve the tourism user experience based on contextual, culture, and live information.

Review of augmented reality agent in education

Augmented reality becomes mature enough to create various applications for end users especially in education field. This is also supported by the presence of more affordable smart phones. The features offered by augmented reality applications could make students more easily understand the lessons and the learning process more fun. Most of current augmented reality applications still present information that is always the same from time to time, there is no personalization in order to obtain an appropriate learning experience for each student. Most of the studies concentrate on the aspect of personalization assures that agents approach is needed to make the learning experience more personal and exciting. This paper aims to review the literature concerning augmented reality agents, its earlier and possible usages in educational setting.

Indoor electrical device control based on activity context and number of occupant utilizing Google Calendar and WSN

Each room in a building has a certain function, for example a lecture hall for learning and teaching activities. Electrical devices in the campus building commonly will be used in accordance with the schedule of room usage. In this paper, we proposed an indoor electrical device control system, which is able to adapt to the kinds of activities and the number of people. The system consists of controller layer and automation layer. Controller layer is software that is integrated with Google Calendar and automation layer is related with hardware infrastructure for controlling. Agendas stored in Google Calendar will be a trigger for those controlled electrical devices. The developed system was given with two kinds of tests, i.e., performance and functionality test. The performance test was applied by measuring the response time when turning the device on/off. The test showed that the average response time needed to turn it on was 2,28 seconds and to turn it off was 2,32 seconds. The result from functionality test showed the capability of the system to control electrical devices in accordance with the kinds of activities and the number of the occupants.
