Heterogeneous Wireless Sensor Network for Big Data Analytics

Abstract

Wireless sensor networks (WSN) are collections of hypothetically large number of physical devices responsible for measuring environmental variables and of transmitting the data to one or more network(s). The data gathered through H-WSN (Heterogeneous Wireless Sensor Network) are to be dynamically process and is subjected to be analysed to monitor the considered issues and support the decision making. Data transmission is accomplished over radio links and routing is based on ad-hoc networking protocols. The sensor devices produce and collect large volume of data from physical-world where quality of data can also vary over time. The data can be represented as numerical measurement values or as symbolic descriptions of occurrence in the world. If we look on wireless sensor data(WSN) applications follows Militery aplications, Environmental applications, Health applications, Home applications, Commercial applications and much more are varied dimention that needs big data analytics. All these analytics system need good performance and has to support uers’s adaptively and also the quality, validity and trust of data collected by wireless sensors. These challaenges requirement have attract researchers to improve performance along with time and cost efficient.
