An Energy-Saving Algorithm of Wireless Sensor Network for the Internet of Things

Article Preview

Abstract:

The internet of things (IoT) is developing very speedily. Wireless Sensor Networks (WSNs) are the perception foundation. It is inconvenience to recharge sensor batteries frequently and the sensor power resource is limited in the WSNs. Therefore, one of the most important problems about a WSN is to save energy. To overcome this challenge, a great deal of algorithms was developed in the last few years such as DYCTC. In this paper, we propose RD-LEACH algorithm. Data transmission depends on the residual energy and the distance between the nodes. It can reduce the number of data sent. It solves effectively the energy saving caused by the invalid send and avoids cluster heads concentrate in a small network. Tests show that this algorithm can save approximately 18% of the energy and prolong the network lifetime under the premise of the network connectivity.
