Data Reduction Techniques in Wireless Sensor Network: A Survey

Abstract

Wireless sensor network is a network which includes sensing and routing via nodes mainly called sensors and sink to monitor physical and environment condition and having many protocols according of usage .Recently, Wireless Sensor Network(WSN) used in many areas like military, hospitals, biological equipments, environment monitoring etc. The limitation of WSN includes lifetime of network, Battery, Bandwidth, Energy, data redundancy and routing etc. In this paper, we mainly focused on data redundancy and energy of sensor nodes.Data reduction is one of the data pre-processing techniques of data mining that can increase storage efficiency and reduce costs. Data reduction (DR) aims to remove unnecessary data while transmission. For this purpose many data reduction strategy introduce according to scenario of WSN. Recent algorithms and techniques based on data reduction are introduced in this survey which helps to increase energy as well as lifespan of network.
