1. Introduction Recent technological improvements have made the deployment of small‚ inexpensive‚ low-power‚ distributed devices‚ which are capable of local processing and wireless communication‚ a reality. Such nodes are called as sensor nodes. Each sensor node is capable of only a limited amount of processing. But when coordinated with the information from a large number of other nodes‚ they have the ability to measure a given physical environment in great detail. Thus‚ a sensor network can

CONCEPT OF WIRELESS ELECTRICITY (Wi-Tricity) Our forefathers marveled at the invention of glowing light bulbs by Thomas Edison in 1879. However‚ to us 21st centurions‚ the light bulb is nothing out of the ordinary. When computers‚ cell phones‚ laptops‚ iPods‚ etc. were invented our antennas tweaked. Now this is what you call invention! However‚ as time’s progressing we are getting used to these devices. In fact‚ charging all these appliances has become so very cumbersome. Each appliance has its

Relocating has become more frequent. Better job opportunities may tempt us to move across town or the country. Moving is a way of life in the military. Whatever the reason‚ you will need to research the new location. Deciding to relocate is a concern because it is time-consuming‚ stressful and expensive. "Join the Navy. See the World." It is not an official slogan‚ but it says a lot . Today’s world is fast-paced and competitive. Job advancement‚ elderly parents‚ better schools‚ marriage‚ and

Abstract The Third-Generation (3G) wireless technologies offer wireless web‚ SMS‚ MMS‚ EDGE‚ WCDMA‚ GPRS etc. 4G is a packet switched technology‚ uses bandwidth much more efficiently‚ allowing each user ’s packets to compete for available bandwidth. It solves the non-standardization problems associated with 3G. Data transfer rate will be 20 to 100 Mbps‚ which is 10 to 50 times than 3G and 10-20 times faster than ADSL. Operating frequency range will be 3 to 10 GHz and the IPv6 protocol will be
