An Energy-Efficient Wireless Sensor Networks Approach based on ADV-LEACH2 Clustering Protocols for Heterogeneous and Homogeneous

This paper describes the architecture of homogeneous and heterogeneous wireless sensor networks (WSN), as well as their applications. To extend the lifespan of WSNs, the energy-efficient dynamic topology approach was developed. The effectiveness of a novel dynamic modified probability-based approach for extending network lifetime by locating the most energy-efficient cluster head (CH) nodes. The proposed method demonstrates the differences in performance between homogeneous and heterogeneous WSN. The mathematical modelling, simulation implementation, and results generation achieved by using MATLAB-2017b. The comparative results analysis of the proposed work is presented in terms of network lifetime based on FND and LND, energy consumption, alive/dead sensor nodes (SNs). The ADV-LEACH2 (HETRO) outperforms the ADV-LEACH2 (HOMO) because of the existence of advanced SNs with higher energy levels in the WSN. By 16.5 percent, the ADV-LEACH2 (HETRO) method outperformed ADV-LEACH1 (HETRO). ADV-LEACH2 (HETRO) approach performed 16.5% better than ADV-LEACH1 (HETRO).
