在能量收集无线传感器网络（EH-WSNs）中，研究了聚类技术以延长其网络寿命。针对地理非均匀能量采集条件下的EH-WSNs，提出了一种自适应聚类控制方案（ACCS），目标是配置相同电池容量节点的均匀EH-WSNs。在实际网络中，节点的电池容量通常不同，因此需要针对电池容量异构的eh - wsn开发聚类方案。然而，由于没有考虑节点上电池容量的不同，传统的ACCS很难应用于当前形式的异构EH-WSNs （EH-HetWSN）。本文提出了一种先进的自适应集群控制方案（AACCS），该方案在传统的自适应集群控制方案的基础上对信标发射功率控制进行了改进，使信标在eh - hetwns中能够很好地运行。评价结果表明，该方案与传统方案相比，具有更高的网络性能。
In energy harvesting wireless sensor networks (EH-WSNs), clustering techniques have been studied for prolonging their network lifetime. The adaptive cluster control scheme (ACCS) has been proposed for the EH-WSNs under geographical non-uniform energy harvesting conditions and targets homogeneous EH-WSNs configuring the nodes with the same battery capacity. In actual networks, the nodes generally equip various battery capacities, and therefore clustering schemes should be developed for the EH-WSNs with heterogeneous battery capacity. However, the conventional ACCS is hard to be applied to the heterogeneous EH-WSNs (EH-HetWSN s) in its current form due to no consideration of the different battery capacities at the nodes. This paper proposes an advanced adaptive cluster control scheme (AACCS), which has the beacon transmission power control modified from the conventional ACCS so as to achieve well-suited operation in the EH-HetWSNs. The evaluation results show that the proposed scheme has higher network performance, compared with the conventional one.
