Comparative analysis of the energy efficiency of hierarchical data transmission protocols in geographically distributed wireless sensor networks

This study conducts a comparative analysis of the energy efficiency of LEACH and PEGASIS protocols within the context of their application in geographically distributed wireless sensor networks. The research aims to identify the relationship between protocol selection and network energy efficiency, as well as to determine the impact of these protocols on the lifespan of sensor networks. Simulation results demonstrate that the PEGASIS protocol surpasses LEACH in both parameters, providing longer network operation and improved energy efficiency. Based on the findings, one of the factors for optimal sensor network deployment strategies can be determined, considering their energy characteristics and operational longevity requirements.
