In this paper a simple and efficient embedded web server is developed. To develop embedded web server installation of operating system on embedded board is eliminated. To check the efficiency of the system instead of taking data, image is acquired as image contain bulky data. As embedded board is having its own IP address the need of well established server is eliminated. In addition the system allows home or company owner to remotely monitor their home or company by using internet. This system can also be utilized by security firms, defense organizations to locate troublesome spot in residential neighborhood and compound.

Introduction World Wide Web, wireless communication tools and gadgets are being extensively utilized by the youth via social networks, smart phone and GPS technologies. The wide spread popularity, acceptance and usage of these technologies has presented an opportunity to research and development engineers as well as information technology service providers to develop and provide value added services. Several systems using Bluetooth, Infrared (IR), Zigbee used for wireless communication has the limitation of range, also, real time applications for image transfer present today are not interactive in nature, as Image contain large amount of information that requires much storage space, large transmission bandwidth and long transmission times. Image acquisition systems with remote accessibility are in great demand in secured area application. In some applications, a single person can monitor and even interact with the ongoing work from a single base station where unmanned devices that will acquire data and relay the data back to the base [1]. Data collection for post processing on a vehicle’s position for an advanced traffic survey is discussed in [2]. A network monitoring system for home automation and intelligent home appliance control system [3] have also been proposed. Zigbee–based technology has been used in local monitoring and controlling of home appliances within homes. For example, Zigbee-based remote information monitoring devices for smart homes and home automation systems were developed and reported [4]. Monitoring and protection building electrical safety system utilizing ZigBee was also presented [5]. The above wireless local range monitoring systems have been extended to a wider remote range using GSM/GPRS networks and wireless TCP/IP based communications [6, 7]. Although these are well-built systems that serve the purpose for a specific task, the user cannot interact with the system. Another unidirectional data transfer is presented in [8], which uses the Global System for Mobile Communications (GSM): a popular wireless choice for connectivity between the data-acquisition units and clients. There are also several systems that allow data to be remotely accessed. As a solution to wireless data collection through the Internet, General Packet Radio Service (GPRS) is a popular choice in several applications. A surveillance system based on GPRS [9] has presented a solution to the data-acquisition problem for remote areas. A long-distance data-collection system for the Earth tide gravimeter, collecting information on temperature, humidity, atmospheric pressure, etc., is designed with GPRS using a hardcoded static Internet Protocol (IP) address [10]. These systems use GPRS without concerns about minimizing the cost of data transfer. Similar types of Internet-based systems, such as those in [11]–[12], are designed to gather a bulk of data before serving them upon request. In these applications, data are compiled in a central server and are then served to the clients via the Internet. Interaction with embedded PC is also important issue published in [13]. The traditional data acquisition system present today which transmits Image uses GPRS connection. The queried Image can be relayed to the client via central server. Using central server to relay the acquired Image has some disadvantages. First the server act as a relay, no direct bidirectional communication between client and embedded system can be established. In addition it requires server software and maintenance which increases operational cost of the system. Therefore central server shown in figure 1 has to be eliminated for a real time system. 119
