چکیده
Wireless Sensor Networks (WSNs) consist of large number of small sensor nodes (SNs) with sensing, computation, and wireless communications capabilities. The SNs are tightly constrained in terms of energy, bandwidth, storage, computation and transmission ranges. Power is the most critical of all of them. Thus, a keen care needs to be taken in order to provide energy efficiency while developing any WSN protocol. Each of these SNs collects data and routes the same to the Base Station (BS). The networks possess selforganizing capabilities since the positions of individual SNs are not predetermined. Cooperation among SNs is the dominant feature of WSNs, where groups of SNs cooperate to disseminate the information gathered in their vicinity to the user. The cost of SNs depends on its parameters, viz., memory size, processing speed and battery.
