In this paper, we present and evaluate a Multi-hop Hierarchical Routing Protocol using Fuzzy Logic (EMHR-FL) for Wireless Sensor Networks (WSN). The proposed protocol uses Fuzzy Logic Inference System (FIS) to select next hop CH (cluster-Head) by taking in to consideration some related metrics ( battery level of CHs, distance between CHs and node density of CHs) in order to maximize the total number of packets transmitted to BS (Base Station). The interest of our solution is twofold. First, it improves performance of classic EMHR in terms of total number of packets received by BS and time of First Node Die (FND). Second, our method makes a better decision of next hop CH selection than classical EMHR. We discuss in depth the system model of the proposed protocol which is planned to reach high performance. Simulation results and relevant performance comparisons with classical protocols are presented.
