An OLAP Service for Data layer of Collaborative Wireless Sensor Network Stack

Abstract

The sensor networks generate immense data and often flood the network traffic with it communication to the cluster nodes and gateways. The enormous data generated has to be analyzed in a uniform manner to extract maximum benefit from the data. The problem is all the sensor nets are on diverse platforms and have different data structure. Effort has been done in this paper to have a uniform sensor data structure and a registry to discover the sensors. A model is proposed with a complete stack of services for the sensor networks. The data service layer is implemented in a practical way with an experimental set up for data gathering and then its analysis by prevalent OLAP techniques with training and validation on trial basis
