WLAN links two or more devices using some wireless distribution method like spread-spectrum or OFDM Orthogonal frequency-division multiplexing radio and provide a connection through an access point to the Internet. Users are given the mobility to move around within the coverage area and still able to connect to the network. It based on the standard of IEEE 802.11 and sales under the Wi-Fi brand name. Due to the ease of installation, Wireless LAN becomes popular in home and it offering wireless...
Abstract: The wireless sensor network is the network which is used to monitor the environment conditions like temperature, pressure, motion at different locations. The nodes in the sensor network sense the environment conditions and send the collected data to the sink; sink is like a base station. After a certain period of time sink broadcast the collected data from the sensor nodes to the internet. Sensor nodes are having limited size and limited battery power .In the far places like...
In order to make a multi-vendor network work effectively you must ensure that the server's operating system, the client's operating system and redirectors are compatible and also to make sure that hardware is compatible to avoid problems like speed mis-match while you are working on a project. Staff costs - It is impossible to find an expert who understands the different products from all the different vendors or who has the necessary qualifications therefore combining products from...
This report seeks to discover how different web based systems are developed and the principles of designing a web based system. Moreover, different technologies required to develop a web based system and compare the technologies to find out the best possible tools to develop the shopping cart software will also be discovered. Analysis of the system requirements and design for shopping cart software will also be carried out in this report. Watch Garden is a renowned high street watch retailer in...
Paradise Beach Guest House is a hotel located in Hikkaduwa, Sri Lanka. The hotel provides room booking, bar and restaurant services. The existing system consists of the following process. In the existing system, all the calculations and other procedures are done 90% manually. Manual processing is too much time consuming and much slower than a computerized system. Even employees are discourage and not totally satisfied with the manual system of this company, since there can be a massive...
Switch The switch is really fast Multiport bridge, intelligent device that keeps switching table and record. Hardware addresses that are on network segments.Switches to the Data Link layer of the OSI model and work with the framework as a PDU. It has almost all the features of bridges primary difference between them is in the implementation details.To receive a box at one port and to forward another port using different methods. The switch is the easiest and faster to cut-through switching....

Mobile location-based services are more useful in entire computer world. GPS, A-GPS, WI-Fi MAC, Cell-ID, OTDOA and Combination of these types (XPS) are primary positioning technologies in use today. Each location technique also is more successful in different environments (namely urban vs. rural and indoors vs. out-doors). Luckily, the strengths and weaknesses of many of these position technologies are complementary, motivating further exploration of hybrid location approaches. But main idea is...
Network security is important these days. It is because nowadays, there are a lot of cyber crime occurred everywhere around the world either it is minor or major. It could bring the company down due to confidential information about the company being exposed to the public such as their rival. Network security involves of the terms and policies implemented by a network administrator to avoid and observe any unusual activities on the network such as someone illegally access into the network, use...
The WiMax network is seen as the future of wireless technology particularly for the internet. Therefore, reliability, capacity and security are essential. WiMax developers have continued to develop new techniques to address the security issues. This paper takes a look at the existing security in WiMax, flaws in the security design and proposes some solutions to the security flaws identified such as the man-in-the middle attack, unencrypted management communication information and the Replay and...
