针对无线传感器网络中单个节点能量和通信距离有限的特点,提出了一种基于免疫遗传的波束成形机制.首先分析了存在相位差的情况下的节点发射系数和选取节点数对系统能耗的影响;然后根据节点的剩余能量和相位结合旋转因子来循环选择参与发射的节点,并引入免疫遗传算法对各节点的发射系数进行调整.理论分析和仿真结果表明,该机制有效均衡了节点间的能耗,延长了网络寿命.
Aiming at the limited energy and communication distance of a single node in wireless sensor network, a beamforming mechanism based on immune genetic is proposed.Firstly, the influence of node emission coefficient and selected node number on system energy consumption is analyzed in the presence of phase difference Then, the nodes participating in the transmission are cyclically selected according to the residual energy and phase of the node in combination with the rotation factor, and the immune genetic algorithm is introduced to adjust the emission coefficient of each node. Theoretical analysis and simulation results show that this mechanism effectively balances the energy Consumption, extending network life.
