摘要
根据无线通信节点部署过程中网络受到区域环境影响和电波传播损耗等实际问题,建立了考虑区域影响的信号衰减模型和无线通信网络覆盖模型,提出了一种综合考虑网络覆盖和通信干扰的优化部署策略。该策略采用了加速遗传算法,大大降低了计算量。基于该优化策略,通过仿真实验得到了特定区域的最优通信节点数和节点部署位置图。
According to the practical problems of network impacted by the local environment and radio wave propagation loss during the deployment process of wireless communication nodes, this paper establishes two models, in which one is signal attenua- tion model considering the local impact and the other is wireless communication network coverage model, and puts forward an opti- mization deployment strategy of wireless communication nodes on the basis of comprehensive consideration of network coverage and communication interference. The optimization mode reduces the calculation by using accelerating genetic algorithm. Based on the proposed optimization deployment strategy, simulation experiment achieves the optimal communication node number and deploy- ment location in target network environment.
