To make the network more reliable and to address energy imbalance issues the cooperative selection of dynamic relay beamforming and energy balanced operation is proposed. Statistic Autonomous Beamforming (SAB) selection of nodes includes picking dynamic relay’s that is used to transmit data. SAB requires very low feedback load, and this strategy is applied for multi user methods like Multiple Input Multiple Output (MIMO). SAB based cooperative scheme is applied by the base station where maximum number of dynamic beams is selected for the active transmission. With the help of transmission power base station can increase the energy harvest at the receiving hub by focussing the power utilized for data transmission on dynamic relay beams. A close-form statistical distribution is derived to calculate the amount of energy harvested in the selected dynamic beams with respect to MIMO users. The performance trade off of average harvested energy, secrecy rate and residual energy of the dynamic relays and the sum rate of multiple MIMO users are analysed. The energy consumption for the proposed scheme is 28% better compared to the existing methods.

为了使网络更加可靠并解决能量不平衡问题，提出了动态中继波束成形和能量平衡操作的协同选择。节点的统计自主波束成形 (SAB) 选择包括挑选用于传输数据的动态中继。SAB 需要非常低的反馈负载，这种策略适用于多用户方法，如多输入多输出 (MIMO)。基于 SAB 的协作方案由基站应用，其中为主动传输选择最大数量的动态波束。在传输功率的帮助下，基站可以通过将用于数据传输的功率集中在动态中继波束上来增加接收集线器的能量收集。导出一个近似统计分布来计算在选定的动态波束中收集到的关于 MIMO 用户的能量量。分析了动态中继的平均收集能量、保密率和剩余能量以及多个MIMO用户的和率的性能权衡。与现有方法相比，该方案的能耗降低了 28%。
