Enhancing the Reliability of WSN Through Wireless Energy Transfer

摘要

Communication reliability is the ability of the network to last long enough without breaking communication between neighbouring nodes that relay information to the final destination. The transfer of energy from the base station to largely spatially distributed sensor nodes in a network with concurrent data transmission is studied. Concurrent data and energy transfer methods require separation of their frequencies and optimum distance between nodes and Energy Transmitters (ETs). Three techniques of energy transfer: store and forward, direct flow transmission and a hybrid will be explored in an unequal clustering environment for concurrent data and energy transmission. The research seeks to explore the use of energy transmitters augmented with energy transfer techniques that redistribute energy in the network to ensure communication reliability. The need for an optimum energy threshold that will determine whether a node is "fit" to relay energy to neighbouring nodes is investigated.
