Area-partitioned clustering and cluster head rotation for wireless sensor networks
Huei-Wen Ferng, Jing-Shiaun Chuang · 2017
A wireless sensor network (WSN) is composed of power-limited devices with constraints of size and condition etc. Due to impossibility to recharge or to replace the batteries of sensors, power control becomes a challenging issue in a WSN. To prolong the network lifetime, clustering is one of viable approaches. Among the clustering approaches, static clustering avoids the energy consumption in periodical re-clustering. However, how to achieve balanced members in a cluster for static clustering forms another issue. In this paper, an area-partitioned clustering scheme with a few control messages is proposed. It not only makes balanced members of a cluster but also possesses more flexible parameters. Different from the cluster head (CH) rotation strategies in the literature, three CH rotation strategies are further proposed to conserve the energy in CH rotation. Via simulations, we show that our proposed clustering scheme along with the strategies outperforms two well-known static clustering schemes, i.e., Hausdorff and ERP-SCDS, in the literature.
