Rotating Energy Efficient Clustering for Heterogeneous Devices (REECHD)

Wireless sensor networks (WSNs) are an essential part of the Internet of Things (IoT). They provide a virtual layer where is possible to collect information about the physical world. WSN devices can be battery powered, produce a large volume of data and have heterogeneous hardware such as computational power, memory, and communication capabilities. Gathering data from battery powered heterogeneous devices in an energy efficient way is a challenging research area. Clustering is one of the solutions which has been proposed by researchers. In this paper we propose a novel Rotating Energy Efficient Clustering for Heterogeneous Devices (REECHD). Our experiments show that REECHD improves the network lifetime when compared to the state of art clustering protocols for heterogeneous WSNs.
