An Energy Efficient Clustering Scheme of Mobile Sink Node in Wireless Sensor Networks

The sensor network environment which is composed of a number of sensor nodes has been used for sink Node to monitor their surroundings at a fixed position. Now sensor nodes are extended to Ubiquitous applications, and sink node are giving mobility and seamless data transmission. This paper is accounting for dynamic clustering focusing on the sink node. After choosing cluster headers, which share base station and data transmission, dynamic clustering can transmit the data of the sink node. This paper defines the optimal hop counter and when a cluster Is made, prolong life time of the network by reducing the whole network energy efficiency. One of the Experiments shows that clustering can be achieved within a single cluster by extending 6 hops at the maximum, and life time makes possible dynamic clustering when node remains more than 20% on average
