Fuzzy Assisted Event Driven Data Collection from Sensor Nodes in Sensor-Cloud Infrastructure

Wireless Sensor Network(WSN) consists of sensor nodes which are deployed densely in an area of interest. The area is intended to be sensed or monitored. Each sensor node is a tiny and power constrained device which is assigned the task of monitoring. One of the most important requirements for wireless sensor networks is systematic collection of data, where sensed data are collected at sensor nodes and forwarded to a base station through number of hops for further processing. This paper presents an event-driven data gathering scheme in a Sensor-Cloud infrastructure. The scheme uses Fuzzy logic to ensure efficient data collection and report a select set of data which is required. Aim of this work is to minimal use of communication resource and reduce overhead while collecting sensor data. Also, an attempt is made to implement the scheme on Tiny OS using TelosB motes for real-time testing.
