Energy Efficient Data Collection in Wireless Sensor Network

Abstract: The use of wireless devices is expanding day by day and is affecting all the aspects of human life throughout the world. Most of these wireless devices are based on very small sensors that translate parameters or events in the physical world into signals that can be measured and analyzed. These tiny sensors thus form a wireless sensor network when employed in a particular area or region. The constraint most often associated with sensor network is that sensor nodes operate with limited energy budgets. As a consequence, the first and foremost important challenge for wireless sensor network is energy efficiency. This paper proposes the various data collection schemes considering energy efficiency as one of the most investigated themes in wireless sensor network based on underlying topology.

Keywords: Wireless sensor network, energy efficiency, data collection, network lifetime.
