A QoS MAC Protocol for Prioritized Data in Energy Harvesting Wireless Sensor Networks

Wireless sensor networks (WSNs) consist of multiple sensor nodes that have the ability to sense, measure and gather information from the surrounding environment. The battery-powered wireless sensor networks (BP-WSNs) have limited lifespan. Therefore, their network performance is always a tradeoff for lifetime. Recently, energy harvesting technology has made it possible to replenish energy by using external energy sources in energy harvesting wireless sensor networks (EH-WSNs). Therefore, it addresses the energy issue faced by BP-WSNs and can also improve the network performance.
