In Wireless Sensor Networks (WSNs), the most important issue is to expand life time of network with the restricted energy resource of sensor nodes. Sensor nodes consume mostly energy when they transmit and receive sensing data. Thus it is important that how to set up a communication method of sensor networks. Generally, to achieve this is a clustering technique. A clustering technique is a communication method which can classify the area by nodes with same or similar sensing and prevent duplicated sensing data to reduce communication. And it can manage sensing data when working locally. To use a clustering technique, the environment to build clustering has to be considered, which means cluster heads counts can affect clustering formation. Thus, this paper proposes use of a clustering technique with zone-based multi-hop communication in WSNs.
