This thesis deals with the feasibility collecting data from web servers running on the nodes in sensor networks. It focuses on sensor network based on IEEE 802.15.4 and 6LoWPAN. The work itself is divided to the node side and server side.REST web services on the node‘s Web server provides sensor data. These data are collected with Java application running on the sensor network server. This servers stores collected data in a database.

Cílem této práce je prozkoumat možnosti uložení DNS dat v LDAP databázi a jejich oboustranné synchronizace s DNS serverem s využitím standardních technologií, paralelizace a jednoduché rozšiřitelnosti o podporu různých DNS a LDAP serverů s různými DNS schématy. Práce dále popisuje různa schémata pro uložení dat v LDAP databázi a analyzuje problémy spojené se synchronizací a navrhuje jejich řešení. Výsledkem je prototyp synchronizační aplikace s doporučenými nastaveními pro DNS server a LDAP databázi, která je schopna efektivně synchronizovat DNS data.

This thesis deals with the design and the implementation of a client/server application for the administration of hosting services. Other solutions of hosting services administration are listed as well and they are contrasted and compared with the assigned solution. A description of the particular hosting services and their setting for the Ubuntu Linux distribution are provided. A communication protocol and a data store serving to save all the client accounts and servers were designed. Basic principles of working with C++ framework Qt and its usage for the implementation of both the server and the client application are demonstrated. The basic settings of the server application enabling it to be launched on the server as a service are mentioned as well. In the last part a description is stated of working with the client applications and administration of the client accounts.

There is always a need for easy-to-follow processes that enable accurate and non-time consuming solutions. Nowadays we see a lot of different approaches to development processes in software engineering. This project is concerned with how to manage a software development process in a reliable, secure and efficient way. Software is available which provides some help for project managers / administrators to work more productively, with effective communication. Using such systems, it is possible to keep track of all the phases of development, including task distribution, making maximum use of previous hands-on experience and increasing productivity, to deliver a finished product in minimum time. No existing solution, however, fulfills all the desirable criteria. This paper describes the motivation, design and implementation of an improved development management system using Active Server Pages and Microsoft Internet Information Services with a backend Microsoft Access Database developed using a waterfall software development process. The resulting system is described and evaluated. This system will be beneficial for software houses, because they can communicate on the web, allowing efficiency gains by avoiding the need to call meetings for distribution of tasks among employees, with the additional advantage of location-transparent team management through the Internet.

Approved for public release; distribution is unlimited / The purpose of this research is to define a centralized database containing all necessary information related to the daily management in an industrial and commercial organization that is publicly owned and equipped with civil personality and financial autonomy. The system is composed of the following subsystems: o Subsystem "Human resource management" o Subsystem "Provisioning" o Subsystem "Financial, budgetary and accounting management" The three subsystems should be installed in a central site and at regional sites. Each site will have its own database. The central database will be supplied with the data, which come from the other sites at the end of the day or according to need via modems. It is necessary to develop a tool for remote database queries in order to accomplish this work. The platform on which the application must be executed is IBM-INFORMIX running on top of the WINDOWS operating system. The database will be a relational database. The framework used in the design and modeling consists of: o Object Oriented Analysis (OOA), which enables the development of high quality software by defining the problem structure. o The Delphi Language, which provides a robust development environment. The installation of the solution will be executed according to the following scenario: o Client/Server architecture with the object oriented development tool DELPHI. o The database will be installed on the central and regional servers. o The application will be installed on the end users' stations. o Data access will be through an open ODBC. This software will present an integrated solution that will provide centralized and accurate data, so that data will be used to derive the right decision at the best time. / Major, Tunisian Army

This study investigates the applicability of node.js for developing web services.Node.js is a software platform for developing event-driven networking applicationsusing JavaScript. Moreover, the language JavaScript is discussed regardingfeatures that facilitate development of event-driven software.Node.js’s selling point is to be a solution to the problem of massive amount ofconcurrent network connections. In addition, it tries to avoid scalability issuesthat may appear in large web applications. To verify and investigate if this holds,an evaluation of the platform was conducted by developing an HTTP boot serverfor Motorola Mobility. The boot server, named Wellington, is used to manageconfiguration and distribution of set-top box software.Furthermore, an investigation and comparison between event based and threadedconcurrency models has been made. Lastly, the maturity of node.js and its ecosystemof libraries and frameworks are discussed.In conclusion, node.js is an interesting piece of technology and it was suitableas development platform for Wellington. JavaScript is a powerful language andworks well to write event-driven server-side software. When learning to buildnetworking applications, node.js is a good start to do so using an event-drivenparadigm.

This thesis has been carried out in cooperation with a company which develops mobile sensor platforms. The sensors measure different types of data such as temperature, pressure etc.. They will communicate through the internet with a server that stores data in a database. This system will be controlled and monitored through a web page. The project's aim has been to develop this system and to implement a server, a database, a website and a client application that simulates sensor signals. In addition, the performance of the server should be measured and a usability test should be performed. To measure the performance of the server, different variants of the client program, which continuously sent data from an increasing number of clients to the server, were developed. In the usability test the participants had to solve a number of tasks after which they answered a survey and were interviewed.The result is a communication system that works according to the requirements and a client program that is also used for testing the server. The investigation of the server performance showed a maximum bandwidth of about 370 kb/s while serving up to 70 clients. The database consumed 95% of the bandwith. However, with a rising number of clients there was a continous decline in the performance. In usability tests, there was a big difference in how people perceive computer programs depending on their experience and education. For this application, the server worked well, but if the project is to be developed into a large scale, it then becomes relevant to move onto an asynchronous working server instead of a thread-server. Queries to a database (MySQL) considerably decreases bandwidth and should be optimized where possible.
