Bi-dimensional Wireless Energy Transfer Algorithm for Maximum Network Throughput

A bi-dimensional wireless energy transfer optimization algorithm for maximum network throughput was proposed to overcome the limited energy of each node in wireless network.Due to the inequality of energy distribution of each node,some energy is transferred successively in node dimension and time dimension to optimize the energy allocation among wireless nodes.Network throughput model was presented by integrating the Gaussian two-way communication model of two wireless nodes and wireless energy transfer.To obtain the maximum network throughout,an analytical energy transfer model was also presented by introducing the energy transfer efficiency of node dimension and time dimension,and a bi-dimensional energy transfer mechanism was proposed based on the model analysis.Experimental results demonstrate that the proposed mechanism can effectively optimize the energy distribution among wireless nodes,and maximize the total network throughput.
