The energy harvesting two-way decode-and-forward relay channel with stochastic data arrivals

In this paper, a two-way relay channel is considered with energy harvesting nodes and stochastic data arrivals at the source nodes. The batteries and data buffers at all nodes are of finite storage capability. The sum throughput maximization problem for this set up is shown to be a convex optimization problem, and the optimal offline policy is found. Numerical results are presented to demonstrate the optimal policy for different channel setups, and its performance.
