Data Collection in Wireless Sensor Networks - A Literature Survey

Abstract

A wireless sensor network (WSN) is made up of several autonomous spatially distributed sensor nodes that can be used to sense information about the physical or environmental conditions like pressure and temperature etc. and to cooperatively pass their data to the destination location through the network. Wireless sensor nodes are energyconstrained and efficient techniques have to be employed while collecting data to maximize network lifetime. Energy is expended in two ways; in sensing the data and in sending the data to sink. This paper focuses on data collection and discusses about several ways in which data can be sent to the sink.
