Wireless Sensor Network (WSN) consists of sensors for measuring and gathering data in a variety of environments. These sensors, with the size and battery constraints, usually have limited transmission ranges due to the low-power wireless radio transceivers. In a sensor network, sensed data should be collected at a centralized location, called sink, for processing and analysis. With limited transmission distances, sensed data may require multiple relays to reach the sink. In this paper, the authors proposed Hybrid Multi-Level Clustering (HMLC) scheme for optimizing power in wireless sensor network. The goal is to create an energy-efficient and effective routing scheme for the wireless networks.
