Stable Energy-Efficient Routing Algorithm for Dynamic Heterogeneous Wireless Sensor Networks

The advancement in recent research in the field of dynamic wireless sensor networks opens the major challenges in terms of Qos (Quality of Service), connectivity, reliability, and many more. The work that is being presented in this literature overcomes such issues by implementing a Stable Energy-Efficient Routing Algorithm (SERA) for Dynamic Heterogeneous Wireless Sensor Networks (DHWSNs). The SERA protocol dynamically selects the cluster heads (CHs) and also provides the re-rotation of such selected CHs at the proper time for sync energy consumption in the network. In SERA, the normalized concept of distance and energy is used for selecting the CHs and the connectivity of such CHs with its neighbors is provided on the basis of threshold distance \(d_o\), thereby, increasing the reliability, QoS, and connectivity in the network. The simulation results justified that the SERA protocol withstands for DHWSNs in terms of QoS, connectivity, reliability, and stability.
