WIRELESS SENSOR NETWORK (Reshma Bhat‚ 3rd sem‚EC) Abstract A Wireless Sensor network (WSN) consists of spatially distributed autonomous sensors to cooperatively monitor physical or environmental conditions‚ such as temperature‚ sound‚ vibration‚ pressure‚ motion or pollutants. The development of wireless sensor networks was motivated by military applications such as battlefield surveillance and are now used in many industrial and civilian application areas‚ including industrial

Wireless communication protocols have evolved rapidly since the introduction of 802.11 Legacy over a decade ago. Over the last 10 years we have seen efficiency and performance increases on all fronts‚ which have lead to greater range and faster transfer speeds. With Legacy 802.11 protocols‚ speeds maxed out at around 2 Mbits/sec and indoor range was only about 20 meters. In 1999‚ the 802.11 protocol got a couple of amendments in the form of 802.11a and 802.11b. Both offered higher speeds and slightly

Maximum Distance reached by the receiver (Theoretical Distance 1000m‚ Open Space) | 25m (Indoor) | 100m (Outdoor) | Receiver Testing Chapter 4 CONCLUSION A mechanism with wireless receiver that can monitor and detect LPG leak‚ trigger an alarm‚ an exhaust fan and solenoid valve at dangerous levels was designed. Wireless receiver was made so that the user can monitor the leak remotely. The sensor was calibrated to be as accurate as the MIRICO LPG Gas Leak Detector. Through t-test it is assumed

kids who like the power hacking give them‚ and typically are not looking to inflict harm to a network. While no attack is good‚ script-kiddies are the easiest to deal with on a network. With the talk about the categories of attackers‚ the issue of wireless security and how to protect your network comes up. There are three types of security protection‚ MAC filtering‚ WEP‚ and authentication. Each has a different way to secure the network against unauthorized access. MAC filtering allows only traffic

Wireless network standards Avery IT/241 06/11/2011 Sherry Desbrough Wireless Network Standards When it comes to communications‚ broadcasting signals‚ and staying within guidelines governed by the FCC and the IEEE here in the United States a system of standards have been developed in order to help the communications and information industry streamline their efforts to work together instead of against each other. Some people feel this is a good practice and conductive toward

Teaching and learning strategies used in an actual session and to be delivered during professional practice. The strategies to be used will depend on several different components‚ e.g. the ability‚ knowledge and background of learners‚ the subject‚ differing learning styles etc. John Dewey (1859-1952) believed that formal schooling was falling short of its potential. He emphasised facilitating learning through promoting various activities rather than by using a traditional teacher-focused method

Road accidents are global tragedies with an ever-raising trend. In Malaysia‚ it represents a major public problem because of the high number of victims involved and also the seriousness of the consequences for the victim themselves and to their families. Accidents are generally classified as single vehicle accidents in which the vehicle is either colliding with fixed objects or with pedestrians Besides that‚ the vehicle may fall in a ditch and multiple vehicle accidents in which two or more than
