Relay selection algorithm based on optimal selection and power allocation

在双向网络中,为减少系统中的硬件负担并保证信息的可靠性,提出一种基于中继节点优化选择与功率分配的中继选择算法。通过采用最优继电器节点选择算法对系统的节点进行优化选择,根据网络中的平均离职率与平均到达率,选择网络中的最佳链路;在其最佳链路的基础上,根据网络寿命的特点引入一个能量价格因子,对其链路上的节点采用功率分配算法,以节省节点功率消耗。实验结果与预期目标基本相符,该算法具有可靠性高与传输速度快的市场优势。

： In the two-way network, to reduce the burden on the system and ensure the reliability of the information, a relay se- lection algorithm based on the relay node optimal selection and the power allocation was proposed. The best relay node selection algorithm was used to optimize the system node selection. The best link in the network was chosen according to the average tur- nover rate and the average arrival rate. Then, based on the best link, an energy price factor was introduced according to the cha- racteristics of the network lifetime. The link power allocation algorithm was used to deal with the nodes on the link, in which way the node power consumption was saved. Test results show that the experimental results basically consist with the expected target, which verify that the proposed algorithm has market advantages of high reliability and high transmission speed.
