Abstract Cluster-based Topology is an energy-efficient topology control method in large-scale wireless sensor networks. The cluster head depletes energy more faster than cluster member and the rotation of cluster head is needed to balance the energy consumption for the whole network. In this paper, ACRA is presented, which rotation energy thredhold is estimated using cluster head real-time energy load. The simulation result show that comparing with LEACH and EDAC, ACRA minimizes the rotation times, prolongs the network lifetime.
