Therefore, to increase the lifetime of WSN, a wise method has to be adopted. So far, the clustering technique has been shown to be efficient in inimizing energy dissipation and prolonging the network lifespan. This study aims to illustrate unequal-sized clustering method, show why unequal-sized clustering emerged and review a set of unequal-sized clustering routing protocols. In this survey, for each protocol studied, the attention is mainly concentrated in the manner of cluster head selection, cluster formation and data routing techniques. ER -
