Networks Project Proposal Introduction

Networks Project Proposal Introduction Networks Project ProposalIntroduction: The home network has potential. It adds growth and knowledge. The home network is important to use and access internet connection easily in home wireless network. This network also provide many other benefits as well like as, sharing a file between your computers in your home network, sharing a media file, sharing a folders between your computers in your home wireless network.iStock This wireless network does not cost much and it has many benefits to provide to connect wireless and non wireless devices across the network. The current network is connected via cables so its wired network. A cable goes from study room to lounge and from bed room to main hall. Its not feasible to connect many devices together in home via cable network because its require cabling through out the home and many times just because of loose cabling you have to connection loss. To overcome this hurdles in home network and to connect additional devices easily to home network wireless networking is very beneficial, so I am approaching to upgrade this wired network to wireless network. So the vast benefit of wireless networking like as I can share my files and folders more easily with my laptop and desktop computers. I can access my pictures from desktop computer to mobile device via wireless home networking. To share a printer in your home network wireless networking is more feasible option to choose because, in wireless network we dont need to run a long cable from router to printer. We can adjust the printer anywhere in home and still it will be connected to your computer via wireless connection. Network up gradation provide the benefit of using more wireless clients easily. Rationale: Connecting computers together (or computer devices) has been a main concern since the beginning of the information age. In the beginning of the computer revolution computing relied heavily upon telecommunication technologies for sharing computing resources, mostly due to the cost and size of those resources. For years, computer networks were nothing more than dumb terminals connected to a supercomputer (mainframe) in another location. This was the beginning of the computer network as we know it today. This web curriculum is designed to assist students in their understanding of computer networks and to help them gain the necessary knowledge that will afford them the skills and abilities of designing and implementing their own personal computer network. Project Goals: Next-generation home networking environments will contain a variety of Internet-ready devices or embedded systems, which will result in increased complexity for the end user. New methods are therefore required to build autonomic networking infrastructures that enable auto-configuration and self-management of the networked elements. In future Internet-based home environments a variety of devices such as PCs, smart phones, networked appliances and embedded systems will be organized into infrastructures and will act together to form a new type of service provisioning platform. Todays typical home environments often contain a few of these Internet-ready devices; in the future there will be even more, including embedded systems like sensors and actuators that are also accessible via Internet technology (e.g. TCP/IP, HTTP, Web services etc). While on the one hand this gives users the freedom to access a rich variety of devices in the vicinity of their homes, on the other it increases the depth of knowledge required to understand what is happening in such a complex networking environment. Novel methods for autonomous networking as well as self-configuration, self-management, self-organization, self-protection and self-healing (self-x) of the networking elements can take responsibility for observing and controlling the home network without directly involving end users. Technology will revolutionize the tools that are used in the home of the near future. Embedded computing, sensing and actuation technologies-coupled with new infrastructure in the built environment itself-will combine to enable new opportunities to support the work of the home. The wireless home networking goal is to successfully connect wireless devices such as laptops, desktop computers, VoIP phone, wireless printer, and network storage drive and wifi cell phone. The other goal is to configure the wireless devices so they can share network folders and print wirelessly in home network and to successfully achieve that we need to install wireless router and cable modem in home wireless network. Resources: Cost: The cost to build network is illustrate bellow, Linksys wireless router Cable modem Wireless printer Virtual Lan Network storage drive (Netgear) Switch Router The cost for internet connection which is provided by ISP is not included in the proposed network cost. The devices which are used in home wireless network are under warranty by the manufacturer for 3years and the technical support is also provided. Research: Advantages Disadvantages of wireless network: Wireless network have advantages and disadvantages when compared with wired LANs. A WLAN will make it simple to add or move workstations and to install access points to provide connectivity in areas where it is difficult to lay cable. Temporary or semi permanent buildings that are in range of an access point can be wirelessly connected to a LAN to give these buildings connectivity. Where computer labs are used in schools, the computers (laptops) could be put on a mobile cart and wheeled from classroom to classroom, provided they are in range of access points. Wired network points would be needed for each of the access points. A WLAN has some specific advantages: It is easier to add or move workstations. It is easier to provide connectivity in areas where it is difficult to lay cable. Installation is fast and easy, and it can eliminate the need to pull cable through walls and ceilings. Access to the network can be from anywhere within range of an access point. Portable or semi permanent buildings can be connected using a WLAN. Although the initial investment required for WLAN hardware can be similar to the cost of wired LAN hardware, installation expenses can be significantly lower. When a facility is located on more than one site (such as on two sides of a road), a directional antenna can be used to avoid digging trenches under roads to connect the sites. In historic buildings where traditional cabling would compromise the faà §ade, a WLAN can avoid the need to drill holes in walls. Long-term cost benefits can be found in dynamic environments requiring frequent moves and changes. Wireless network also have some disadvantages: As the number of computers using the network increases, the data transfer rate to each computer will decrease accordingly. As standards change, it may be necessary to replace wireless cards and/or access points. Lower wireless bandwidth means some applications such as video streaming will be more effective on a wired LAN. Security is more difficult to guarantee and requires configuration. Devices will only operate at a limited distance from an access point, with the distance determined by the standard used and buildings and other obstacles between the access point and the user. Methodology: Solution: find-ip-address To overcome the technical issues take necessary steps to build wireless home network. To solve the wireless range problem with the 802.11b/g, in this network 802.11n wireless standard is chosen. So it will provide wide range of wireless network and it will be enough for small to medium size home. The wireless security is configured so the home wireless network can be protected. To protect wireless security WPA2 personal security encryption is configured and MAC address allocation is also configured so the wireless router will not provide access to any other device and the home wireless clients devices will be secured. The firewall is also enabled on Linksys wireless router so it will provide security from outside. From outside no one can hack your home network and harm the computer systems. The ultimate in wireless security measures, shutting down your network will most certainly prevent outside hackers from breaking in! While impractical to turn off and on the devices frequently, at least consider doing so during travel or extended periods offline. Computer disk drives have been known to suffer from power cycle wear-and-tear, but this is a secondary concern for broadband modems and routers. Summary: To build wireless home network, using this simple three-step approach: 1. Identify the WLAN design thats best for your situation 2. Choose good wireless gear 3. Install gear and test the configured WLAN Wireless offers tangible benefits over traditional wired networking. Each computer you wish to connect to a WLAN must possess a wireless network adapter. Wireless adapters are sometimes also called NICs, short for Network Interface Cards. Wireless adapters for desktop computers are often small PCI cards or sometimes card-like USB adapters. Try to install your wireless router in a central location within the home. The way Wi-Fi networking works, computers closer to the router (generally in the same room or in line of sight) realize better network speed than computers further away. In densely populated areas, its not uncommon for wireless signals from one persons home network to penetrate a neighboring home and interfere with their WLAN. This happens when both households set conflicting communication channels. Fortunately, when configuring an 802.11n router, you can change the channel number employed. For example, you may choose any WLAN channel number between 1 and 11. If you encounter interference from neighbors, you should coordinate channel settings with them. Simply using different channel numbers wont always solve the problem. However, if both parties use a different one of the channel numbers 1, 6 or 11 that will guarantee elimination of cross-WLAN interference. Wireless LANs suffer a few more reliability problems than wired LANs, though perhaps not enough to be a significant concern. 802.11n wireless signals are subject to interference from other home appliances including microwave ovens, cordless telephones, and garage door openers. With careful installation, the likelihood of interference can be minimized. Wireless networking products, particularly those that implement 802.11n are comparatively new. As with any new technology, expect it will take time for these products to mature. Wireless LANs using 802.11n support a maximum theoretical bandwidth of 300 Mbps. Furthermore, Wi-Fi performance is distance sensitive, meaning that maximum performance will degrade on computers farther away from the access point or other communication endpoint. As more wireless devices utilize the WLAN more heavily, performance degrades even further. Overall, the performance of 802.11n is sufficient for home Internet connection sharing and file sharing, but generally not sufficient for home LAN gaming.
