摘要
论文提出了一种面向配用电物联网(PD-IoT)的异构无线通信网络最佳适配性动态接入策略.首先,引入网络属性效用函数,并基于聚合效用建立量化PD-IoT业务终端与无线网络适配性的评价模型;其次,综合考虑PD-IoT业务通信需求和通信网络性能来完成业务终端对各网络属性的动态定权;再次,引入网络切换控制机制以确保终端与无线网络间可靠的通信连接和通信质量;最后,通过案例仿真验证了论文异构网络接入选择策略的有效性.
Abstract
A dynamic access strategy for optimal adaptation of heterogeneous wireless communication networks for the distribu-tion of electricity of things(PD-IoT)is proposed.First,a network attribute utility function is introduced,and an evaluation model is established to quantify the adaptability of PD-IoT service terminals and wireless networks based on the aggregated utility.Sec-ond,the dynamic weighting of service terminals to each network attribute is accomplished by considering PD-IoT service communi-cation demand and communication network performance.Third,a network switching control mechanism is introduced to ensure reli-able communication connection and communication quality between terminals and wireless networks.Finally,the effectiveness of the heterogeneous network access selection strategy is verified by case simulation.Finally,the effectiveness of this paper's heteroge-neous network access selection strategy is verified through case simulation.
