Wireless sensor networks (WSNs) are gaining an increasing attention due to their omnipresent nature and their wide deployment in the Internet of Things and other emerging fields. Despite this importance, little researchers focused on enhancing the Quality of Service (QoS) criteria of WSNs, particularly in hierarchical routing protocol. Therefore, this study proposed a new protocol to enhance the QoS of hierarchical routing protocols. In particular, LEACH-G-K is based on LEACH protocol. LEACH-G-K divided the area into equal size clusters using the grid function. Then, for each cluster, the K-means algorithms is applied to gather their nodes near to the centroid, where the cluster head is located. The obtained simulation results showed that LEACH-G-K can enhance the energy consumption and QoS criteria compared to Low Energy Adaptive Clustering Hierarchy protocol (LEACH), Threshold Sensitive Energy Efficient sensor Network protocol (TEEN), Low Energy Adaptive Clustering Hierarchy-KMeans protocol (LEACH-K) and MDC maximum residual energy LEACH protocols.
