摘要：Wireless sensor networks (WSNs) have been paid more and more attention recently for the application perspective. Providing energy-efficient and reliable routing protocol in large-scale wireless sensor networks is a challenging problem. In this paper, we present a dynamic multi-level clustering protocol architecture, in the proposed method the route paths from the cluster head to sink change frequently according to the environment. Furthermore, in order to improve the energy efficiency of the whole architecture, assistant nodes are introduced to reduce the cost of retransmission. This architecture achieves better energy-efficiency by reducing retransmissions and cluster hierarchy establishment. Our results show that this architecture can improve energy efficiency in a severe environment.
