The applications for Distributed Sensor Networks are varied, typically involving some kind of monitoring, tracking, or controlling. Specific applications include habitat monitoring, object tracking, nuclear reactor control, fire detection, and traffic monitoring. In a typical application, a WSN is scattered in a region where it is meant to collect data through its sensor nodes.

The development of wireless sensor networks was motivated by military applications such as battlefield surveillance. They are now used in many industrial and civilian application areas, including industrial process monitoring and control, machine health monitoring, environment and habitat monitoring, healthcare applications, home automation, and traffic control.

In addition to one or more sensors, each node in a sensor network is typically equipped with a radio transceiver or other wireless communications device, a small microcontroller, and an energy source, usually a battery. A sensor node might vary in size from that of a shoebox down to the size of a grain of dust.

Thank you for visiting Distributed Sensor Networks.   :-)      :-)

I want to use it for my Dish Network, but I dont have a phone jack next to my TV. I heard they make something that plugs into the phone jack, then has a remote sensor you plug into something else to transfer the signal.

Lets say i am measuring temperature. Should I use wireless network b/g to fetch the data from sensor. I think that will be too much work.

I think the best way is to create a proprietary system the sensor sends data using RF (with certain security), it is then picked by the receiver which is interfaced with the PC The benefit is, the sensor can be placed far from PC and it will not be that hard to implement.

What do you think is the best way to do it? Can i use PCI card? What is available in the market. Thanks

Google Tech Talks April 1, 2009 ABSTRACT Presented by Martin Vetterli A sensor network is a spatio-temporal sampling device with a wireless communications infrastructure. In this talk, after a short overview of the Center on Mobile Information and Communication Systems, where large scale ad hoc and sensor networks are being studied, we will address the following questions related to large sensor networks and their applications in environmental monitoring. 1. The spatio-temporal structure …

CarTel is a distributed, mobile sensor network and telematics system. Applications built on top of this system can collect, process, deliver, analyze, and visualize data from sensors located on mobile units such as automobiles. A small embedded computer on the car interfaces with a variety of sensors in the car, processes the collected data, and delivers it to an Internet server. Applications running on the server analyze this data and provide interesting features for users. cartel.csail.mit.edu…

There is a method for detecting computer virus attacks on a network computer that are sent from a remote host. These viruses reach the network through requests for communication (e.g. e-mail) that are identifies as “packets”. For example, the “WORM flood” virus ties up the network computer by “flooding” the network with multiple packets. Security experts can detect this type of virus attacks if at least 1 packet is observed by a network sensor.

Assume that the probability of observing a single packet sent from a new virus is only 0.001. If the virus sends 150 packets to a network computer, what is the probability that the virus is detected by the sensor?
