Can Sensors Collect Big Data? An Energy-Efficient Big Data Gathering Algorithm for a WSN

Recently, incredible growth in communication technology has given rise to the hot topic, big data. Distributed wireless sensor networks (WSNs) are the key provider of big data and can generate a significant amount of data. Various technical challenges exist in gathering the real-time data. Energy-efficient routing algorithms can overcome these challenges. The signal transmission features have been obtained by analyzing the experiments. According to these experiments, an energy-efficient big data algorithm (big data efficient gathering, BDEG) for a WSN is proposed for real-time data collection. Clustering communication is established on the basis of a received signal strength indicator and residual energy of sensor nodes. Experimental simulations show that BDEG is stable in terms of the network lifetime and the data transmission time because of the load-balancing scheme. The effectiveness of the proposed scheme is verified through numerical results obtained in MATLAB.
