Strategy of Terminal Access to Heterogeneous Wireless Communication Network in Power Distribution Internet of Things
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.
