Advancing Energy Efficiency in Wireless Sensor Networks for Prolonged Lifespan and Enhanced Resilience
D. Archana, Shanmugapriya Prakasam · 2024
In Wireless Sensor Networks (WSNs), the paramount concern revolves around energy efficiency, aiming to extend the network's operational lifespan. Achieving this objective encompasses several key facets that collectively contribute to the network's longevity and robustness. Firstly, developing cutting-edge routing algorithms and protocols plays a pivotal role. Secondly, energy efficiency has been increased through a suite of optimization techniques. These encompass the fine-tuning of routing paths, reduction of redundant packet transmissions, and the application of data aggregation and compression methods. These measures minimise redundant data transmissions, and sensor nodes can operate for extended durations without necessitating battery replacements. Thirdly, novel energy routing techniques address the challenge of balancing energy consumption among nodes. These methods dynamically adjust routing paths and traffic distribution, mitigating energy depletion disparities. This balanced energy consumption fosters network resilience and prevents premature node failures, ultimately bolstering the network's lifespan. Lastly, an essential component of energy-efficient transmission involves harnessing energy harvesting techniques. This strategy aims to replenish sensor node energy reserves by seamlessly integrating energy-harvesting mechanisms into the network. The optimization of energy scheduling and utilization based on energy availability and node requirements reduces the network's reliance on finite battery power, facilitating prolonged network operation through the utilization of renewable energy sources.
