Energy is the main issue in the Wireless Sensor Network (WSN) as these networks contains the battery operated nodes. The energy consumption can be reduced by efficient routing in the network. The efficient routing needs the proper cluster head selection along with the proper cluster size. Moreover, the cluster shape is also an important factor to optimize the clustering. This paper studies various routing schemes in the WSN. These schemes cover the cluster shape, cluster size and cluster head selection processes.
