Fast and Efficient Data Collection in Wireless Sensor Networks

Abstract

Wireless sensor networks utilize large numbers of wireless sensor nodes to collect information from their sensing terrain. Wireless sensor nodes are battery-powered devices. Energy saving is always crucial to the lifetime of a wireless sensor network. Recently, many algorithms have been proposed to tackle the energy saving problem in wireless sensor networks. In these algorithms, however, data collection efficiency is usually compromised in return for gaining longer network lifetime. There is a strong need to develop wireless sensor network algorithms with optimization priorities biased to aspects besides energy saving. In this paper, a fast and efficient data collection network structure for wireless sensor networks is proposed. The objective of the proposed network structure is to minimize delays in the data collection processes of wireless sensor networks. We give a logical overview of proposed model by a taking example of sensor network having many nodes and try to form a network structure in it.
