Wireless Sensor Networks (WSNs) play an important role in pervasive and ubiquitous systems. Even though the advances in embedded systems, the energy consumption is still open issue in WSNs. In this context, hierarchical routing protocols provide energy-efficiency, scalability and reliability for WSN applications. With this goal in mind, this paper proposes to adopt a Cluster-based approach for ENERgy-efficiency in the WSN (CLENER) protocol. The main purpose of CLENER is to provide energy-efficiency by using fuzzy logic for cluster formation and a probability function for Cluster Head election. Simulations were conducted to show the benefits of CLENER compared with LEACH and EECHS. According to the simulation results, CLENER extends the network lifetime by 19% and 18%, and increases the packet delivery ratio of LEACH and EECHS by 15% and 14%, respectively.
