Embodiment Construction
[0047] Below in conjunction with accompanying drawing, the present invention will be further described:
[0048] The present invention is a communication mode access selection method for a heterogeneous wireless network of an intelligent distribution network. When the current access communication mode changes in the network state or network demand at time t, the method obtains GPRS, LTE, 3G, micro-power wireless, WIFI, etc. The index value of the communication mode at the previous moment (t-1 moment) and the current moment (t moment), including received signal strength, network bandwidth, network delay, and packet loss rate, constructs an initial decision matrix, and makes the initial decision matrix dimensionless Process to obtain a dimensionless matrix, and use the entropy weight method to obtain the first weight vector a of the indicator 1 , using the rough set theory to obtain the second weight vector a of the index 2 , the integrated first weight vector a 1 and the seco...
