Abstract

Sensor network is a collection of addressable nodes of a data network, capable of capturing data in real time. In this sense, sensor network is a distributed computing and communication system or a resource. To our minds, the first and most obvious such a system would be the Internet, with a vast number of nodes designed for data processing, resource sharing, and communications. Hardware engineering advancement in last few years has given rise to devices with smaller and smaller footprint capable of collecting many different kinds of data. Of course, the sensor network that we all possess, and we cannot function without it, is our own brain, albeit not quite similar to the silicone-based distributed computing and communication system. In very recent years, devices with built-in global positioning satellite (GPS) have entered the arena of sensor network. We have now on our hand very smart and immensely capable sensor network with the ability to collect vast amounts of data, ready for processing, and guiding us in decision making.
