This paper introduces a static Tree-based Multiple-Hop Distributed Hierarchical Agglomerative Clustering (TMH-DHAC) approach for wireless sensor networks (WSNs). The proposed TMH-DHAC is derived from the Hierarchical Agglomerative Clustering (HAC) and the distributed HAC (DHAC) methods. TMH-DHAC adopts an energy-aware cluster-head election policy to balance the energy consumption and workload among sensor nodes in the network. The multi-hop tree structure provides the near-optimal routes for intracluster data transmissions. The proposed TMH-DHAC method for the time-slot allocation enables simultaneous conflict-free communications between different pairs of sensors and increases the maximum transmission throughput. The simulation results show that TMH-DHAC performs better than previous approaches: LEACH, LEACH-C and the DHAC-RSS (Received Signal Strength) protocols, in terms of the network lifetime, total data amount, energy efficiency, and average transmission distance.
