ZigBee network technology is used for low data rate Wireless Personal Area Networks that requires long battery life and is affordable. The ZigBee protocol refers to the entire network protocol stack. ZigBee applications run on top of ZigBee network, MAC and physical layers. A ZigBee network is capable of supporting up to 65,535 nodes. ZigBee network is used in many areas such as environmental monitoring systems, personal health care and consumer electronics. In ZigBee network the nodes can be mobile and fixed.
1.2 ZigBee Topologies
The three ZigBee network device types are end device, router and coordinator. ZigBee support three kinds of topologies. These are star, tree and mesh. In all topologies the ZigBee network must contain one coordinator. The coordinator is responsible for allowing other devices to join the network, selecting transmission channels and for starting the ZigBee network. The coordinator can also route traffic and it’s the root node in tree and star topologies. ZigBee network supports single and multiple Personal Area Network (PAN). The routers only exist on tree and mesh topologies. The end devices in all ZigBee topologies can only communicate with their parent nodes; the router or coordinator. The three ZigBee topologies are described below.

• Star – This is the most basic ZigBee topology. This topology usually consists of end devices and a coordinator. Routers can be part of the star topology, but they will simply function as end device and will not perform any routing functions. The central node is the coordinator and it handles all network traffic as well as providing ZigBee coordinator services. In the star topology all end devices send all their data through the central node. Star topology is not very good for ZigBee networks with large number of nodes because the central node need to handle all the traffic so network bottleneck and...

Emerging Wireless Service

...An emerging technology is one that offers a relatively undiscovered method to solve a daunting wireless problem in a cost-effective way. The methods or technology itself may be non-conventional, but emerging technologies that become mainstream are typically more evolutionary than revolutionary. This is because a technology cannot succeed by itself – it must bring the whole sector with it. This paper presents an overview survey of emerging wireless technologies – 802.11(wi-fi), 802.15.4 (Zigbee)and 802.16 (wi-max). WI-FI: Wi-Fi is a popular technology that allows an electronic device to exchange data wirelessly using radio waves over a computer network including high speed internet connections. A device that can use Wi-Fi can connect to a network resource such as the Internet via a wireless networl access point Such an access point has a range of about 20 meters (65 feet) indoors and a greater range outdoors. Wi-Fi works with no physical wired connection between sender and receiver by using radio frequency (RF) technology, a frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. The cornerstone of any wireless network is an access point (AP). The primary job of an access point is to broadcast a wireless signal  that computers can detect and "tune" into. In order to connect to an access point and join a wireless......

The Smart Home

...Ruth Rininger Professor Alma Scott CINT 106 7 May 2013 The Smart Home On your morning commute, have you ever thought, did I turn the hallway light off? What about the coffee maker? Did I set the security alarm? With a smart home, you wouldn’t worry about these things at all; you would just pull out your smart phone or your work computer, visit the Internet, and control your house. Have a hard day at work? When you walk in the door, you can have your favorite music playing and the lights dimmed. Worried about what your teenager is doing to your house while you’re away? Just watch him or her online from wherever you are. Do thoughts of the smart home bring to mind images of the Jetsons? The technology is not quite to that level, but give it time. What is a smart house? According to Craven, “a smart house is a house that has a highly advanced automatic systems for lighting, temperature control, multi-media, security, window and door operations, and many other functions” (1).

...recognition and verification technique can easily replace an attendance sheet and save time wasted on calling out roll numbers in the class. A fingerprint detecting device needs to be placed in each classroom and students would be made to swipe their finger over the sensor so as to mark their presence in the class. The database would contain all the fingerprints beforehand. So, the moment a finger would be swiped, a check would be carried out 3 with the existing database and the corresponding student would get a present mark on his attendance record maintained in a server. The transfer of the fingerprint from the device to the server can be carried out wirelessly using certain wireless adapters which can together form a wireless network in a short range and carry out the verification process.

Question1

...this area, and given the numerous obstacles to digging, it would be prohibitively expensive to install. The only choice left here is to use the wireless technology. But what form of wireless signal would we use? The wireless signal would have to go through walls (eliminating infrared), be able to traverse approximately 12kms (eliminate Bluetooth, Wireless Lans, Ultra-wideband, again infrared and ZigBee) and be able to carry a high-speed signal (again eliminate Bluetooth and ZigBee). for obvious reasons, microwave, satellite and WiMAX are reasonable solutions. The new distribution centre is located in an industrial area, industrial environments with heavy machinery produce electromagnetic radiation, and wireless transmission also can be disrupted by electromagnetic noise and interference from other transmisiions.Sunspots, although they do not happen often, can be disruptive to satellite transmissions. (Might eliminate satellite). It is worth noting that microwave transmission can be hampered by bad weather. Microwave will work only if the headquarters and the new distribution center are tall and no obstructions, such as other buildings are in the way (might eliminate microwave). In order for the company to establish a long-distance, high-throughput wireless connection, 802.16 (WiMAX) technology should be used. This technology which stands for Worldwide Interoperability for Microwave Access, is able to transmit and receive signals up to 30 miles when the antennas are fixed.......

Pervasive Computing

...Pervasive Computing Pervasive computing is a trend towards information being readily available to anyone, anywhere at anytime. This trend is due to the decrease in powerful microprocessors being embedded in everyday objects enabling users and devices to connect wirelessly to the internet, devices, and to other users from wherever they may happen to be. Pervasive computing thus provides users with the ability to access and take action on information conveniently. This idea of pervasive computing is to enable users to interact other users and access information in a more natural form such as merely speaking and gesturing. Mobile phones and personal digital assistants (PDAs) have become very much a part of everyday life due to the many functions they provide and the functions that are yet to be implemented. These functions are made possible through chips being made smaller and able to compact different functionalities. Pervasive computing will usher in new forms of collaboration, communication, the ease of acquiring information, and performing functions that will become the norm in homes, clothing, and businesses. What pervasive computing does is eliminates the steps to complete tasks. For example if a student needed to go to a library to do research for a term paper he/she would get dressed, drive, walk, or take public transportation to reach the library, and ask a librarian to direct him/her to the resources. Today all it takes is having an internet connection......
