In modern world use of WSNs (Wireless Sensor Networks) is increased in many applications and many people are doing research in WSNs for enhancing the use of WSNs. Routing protocols are divided into flat, hierarchical routing based on network structure. In this paper, the authors discussed cluster formation and cluster head election protocols and their advantages and disadvantages. By considering the advantages of clustering they developed taxonomy on clustering routing method. At last they conclude and summarized the paper along with future direction.
