Location based multimedia application for mobile gadgets

Nowadays tourists all around the world don't fully enjoy their vacations as they intended to. In order to assist tourist on their trip planning a location-based multimedia application is proposed. This application uses specific location points as the main criteria for retrieving and/or uploading information. It also allows the user to contribute to the application by uploading data. Therefore, tourist will be able to retrieve data related to where they are, as they travel. Also they will be able to contribute with data that they gather while traveling. In this paper, the main parts that constitute the application are discussed, along with the methodologies taken to develop the application, as well as some of the tools that will be used to develop the application. Furthermore, using a Gantt chart, I give a brief preview of the tasks that are going to be completed throughout the development of the project

Abstract-Within the last decade, the continuous development of mobile technology has motivated an intense research in mobile data services. Among these services, location-based services and location-dependant queries have attracted a lot of attention from the software industry as well as from researchers. Although a number of locations based service methods have been proposed, the performance is not satisfactory in the case of dynamic data management problems that introduce high overhead in update and query operations. In this paper, we introduce a proxy based distributed dynamic data management architecture for location based services that reduces network cost with required quality of service (QoS). The system proposes a distributed hierarchical database structure with collocated proxy for efficient service delivery to location-dependant queries especially Range Queries (RQ). The system that we propose have the following advantages. i) It performs efficient processing of location dependant queries, especially Range Queries spanning over multiple network cells ii) It reduces wireless communication between mobile devices and servers. iii) The system is scalable where location data is distributed and arranged hierarchically. We use proxy objects to carry out processing task for each mobile user. Thus proxies play an important role and in charge of routing the queries to different (distributed) databases and present the results to queries efficiently. Simulation study shows the effectiveness of our proposed architecture
