Wireless Sensor Networks Communication: Energy Efficient Paradigm

Abstract

As the number of application in wireless sensor networks are increasing because of ongoing miniaturization of electro-mechanical parts, its subsidiary elements and drastic decrease in the cost. The communication among sensor nodes consumes more energy than the actual computation of information. The consumption not only takes place in transmission state, but also relatively high in idle state. The focus of this paper is to identify the main source of energy dissipation, as well as counter measure to ensure prolonged network lifetime. In addition to these, different types of protocols for routing, medium access control and transport protocols are presented and clarified by the means of examples.
