ABSTRACT
Wireless sensor networks (WSNs) have attracted enormous attention for their potential applications in diverse areas such as disaster warning systems, environment monitoring, health care, safety, surveillance, intruder detection and so on. A WSN could be deployed to detect a forest fire in its early stages. A WSN-based traffic system is deployed in many applications. One of the main objectives of such a system is to minimize congestion of the whole traffic network and optimize the use of road capacity. Sensors are used for collecting information about physical and environmental attributes such as weather, crop and soil information. In industry, a sensor can predict the failure of a bearing or of machines. The medical applications of wireless sensor networks aim to improve existing health care, and monitoring services especially for the elderly, children, and the chronically ill. Sensor technology provides teachers with an exciting alternative to the timeconsuming task of manually logging, and observing science experiments.
