Multi-hop dynamic clustering LEACH protocol for large scale networks

In wireless sensor networks (WSNs), reducing sensor node energy consumption and increasing network lifetime are becoming more and more challenging due to large scale. Hierarchical protocols, especially Low Energy Adaptive Clustering Hierarchy (LEACH), are considered as the best energy-efficient for WSNs. However, LEACH need to be enhanced to support scalability in large WSNs. In this paper, we propose a new protocol based on dynamic clustering and multi-hop transmission, named multi-hop dynamic clustering LEACH (MDLEACH). Through both analytical analysis and simulation results, we prove that the performance of MDLEACH protocol is better than conventional LEACH in terms of network lifetime, energy consumption and data transmission.
