摘要
针对传统抗干扰通信存在局部搜索能力差、后期收敛速度慢等问题,提出一种基于改进人工蜂群算法的低功耗滴灌装置控制过程层抗干扰通信方法。根据人工蜂群算法的食物源、雇佣蜂、非雇佣蜂计算获得领域搜索的改进算法,利用改进算法建立控制过程层抗干扰模型,通过模型调整发射功率、干扰抑制方式、可用频率子带数、调制编码方式的参变量,最后将误包率作为约束条件对目标函数取合理数值,以此得到抗干扰通信的最优参数配置。仿真结果证明,所提算法具有极高的抗干扰能力,并且在确保通信输送稳定性的前提下,具备低功耗及高效率传输的特点。
Due to poor local search ability and slow convergence rate in traditional anti-interference communication,an anti-interference communication method in controlling process layer of low-power drip irrigation device based on improved artificial bee colony algorithm was put forward.According to the food source of artificial bee colony algorithm,employed bee and non-employing bee,the improved algorithm of neighborhood search was found.The anti-interference model of control process layer was built by the improved algorithm.The transmission power was adjusted through the model.Then,the interference suppression mode,the number of available frequency sub-bands,and the parametric variables of modulation and coding mode were adopted.Finally,the packet error rate was taken as the constraint condition to get a reasonable value of objective function,so as to obtain the optimal parameter configuration of anti-interference communication.Simulation results show that the proposed algorithm has very high anti-interference ability,low power consumption and high efficiency transmission on the premise of ensuring the stability of communication transmission.
