Abstract :
This paper describes the sensor networks that are wireless systems in which large number of sensors can be deployed. A snapshot of the first-generation hardware and software for sensor networks, the requirements of the sensor nodes by their capabilities, and an outlook on future implementations are focused. These networks have been enabled in part by advancements in silicon sensor technology, low-power microcontrollers, chip-based radios, ad-hoc networking protocols, and operating systems and languages for embedded systems.
