Unequal clustering in wireless sensor network: a review

<p><span>In recent time, the applications' diversity of wireless sensor network (WSN) attracts many researchers. WSN comprises nodes with limited battery power. Therefore, energy consumption should be controlled to optimum. Clustering is an efficient solution for management in WSN, but clustering does not consider sink node location. It will cause hole problem multi-hop routing. Energy was solved by unequal clustering. A review various mechanisms presented this paper. The comparison between based on cluster head election process, properties, simulation parameters and efficiency highlight a more scalable algorithm </span>WSN.</p>
