Energy Cooperative Transmission Policy for Energy Harvesting Tags

To sustain communication reliability and use effectively the energy harvested from the surrounding, it is crucial to consider energy sharing between energy harvesting tags (EHT) in a multiple access network, which are basic building blocks for the internet of things (IoT) applications. This technique also achieves higher throughput compared with the non-cooperative strategies despite energy losses occurred during energy transfer. We propose an energy-sharing communication strategy for a multiple access network of tags that depends on the harvested battery energy. We design an optimal communication scheme for EHTs that maximises the long-term joint average system throughput using a Markov decision process (MDP) model. Simulation results show that the proposed energy cooperative policy produces improved performance than traditional policies.
