Wireless Sensor Networks (WSNs) are consists of several sensors which are connected through a gateway using wireless communication. These smart sensors are directly interacting with environmental condition such as temperature, pressure, humidity, vibration etc. and communicate these over the wireless network. Communication overhead is increase when any sensor node is fail. The protocol will follow multiple path to destination node. So energy consumption is more. Multiple paths are increased when sink node is mobile. In this paper, the authors introduce cluster technique for making cluster in network to reduce communication overhead due to less connection with sink and make the network hierarchical.
