基于信息中继节点的能量和信息同传模型及协议

Simultaneous energy and information transmission model and protocol based on information relay nodes

建立基于自身节点作为中继的信息和能量同时传输模型,中继节点既可以发送自身采集的信息到源节点,又可作为中继节点帮助源节点与目的节点进行能量和信息的传输。采用能量分割(Power Splitting, PS)协议,中继对信号采用解码转发方案,运用非线性规划算法对该模型和协议进行优化并得到最优解。仿真结果表明,该最优解可使模型的吞吐量最大,靠近目节点位置为最优中继节点位置。

simultaneous information and energy transmission model based on node’s relays is built, where relay nodes can not only send out its information to source node but act as a relay node to help the transmission between the source node and destination node. Power Splitting(PS) protocol and decoded forwarding scheme are used for the relay. Nonlinear programming algorithm is applied to optimize the model and protocol. Simulation results indicate that the largest throughput is obtained under the optimal conditions, and the location of the optimal relay node is near the destination node.
