Abstract¬¬¬ ¬—Big Data is a broad term for massive data sets having large, more various structure with the difficulties of storing and analysing for further processes and results. Energy efficient big data gathering in wireless sensor networks is a challenging research area. The most effective solution to overcome this challenge is to make the use of Sink node’s mobility. It also have some additional challenges like Sink node trajectory and Cluster Formation. To avoid these challenges a new mobile sink routing is proposed. This method is a clustering based EM technique. In previous research ‘LEACH’ algorithm is used for clustering. But in order to increase the efficiency ‘HEED’ algorithm is used in this paper. So the Energy consumption is reduced and increases the lifetime of the sensors.
Keywords: WSN, Clustering, HEED algorithm, and Energy efficiency.
