An energy efficient hierarchical routing algorithm for IoT-enabled WSNs

In the recent era, the Internet of Things (IoT) is booming technology used for real-time problems. Wireless Sensor Networks (WSNs) technology in IoT extracts relevant information from surroundings that find applications in smart cities, smart home automation, etc. A WSN consists of energy-limited sensors that are deployed in the working field. Therefore, energy efficiency is a vital issue that needs to be resolved to increase the network lifetime. This paper presents a hierarchical routing algorithm that aims to increase network lifetime by eliminating extra energy losses that occur during transmission. This paper proposes an efficient way of cluster formation, cluster head selection, restructuring of clusters, and changing of cluster head according to newly created clusters after a regular interval. The results of the proposed scheme show better network lifetime, energy efficiency and packet received ratio as compared to the other state-of-the-art algorithms.
