Embodiment Construction

[0015] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0016] like figure 1 As shown, a Markov model-based multi-AP adaptive handover method includes the following steps:

[0017] 101) collect real-time passenger flow, combine BP neural network and Markov state model to predict passenger flow, and real-time rolling forecast, that is

[0018] First construct the passenger flow prediction benchmark based on BP neural network, and calculate the residual sequence between the state sample value of the passenger flow data and the predicted value of the Markov model; calculate the state transition probability matrix according to the state of each residual sequence, and then predict the future state , so as to obtain the state of the predicted value, take its weighted center to correct and calculate the pr...

Abstract

The invention discloses a multi-AP adaptive switching method based on a Markov model. The method comprises the following steps: 1) collecting a real-time passenger flow volume, predicating the passenger flow volume in combination with a BP neural network and the Markov state model, and rolling for predication in real time; and 2) establishing an offline query table and a control query table through a membership function, and carrying out fuzzy control and real-time site control on AP allocation to realize multi-AP adaptive switch. The multi-AP adaptive switching method based on the Markov model disclosed by the invention has the beneficial effects that: the multi-AP adaptive switch is a complicated system project that involves information science, geographical science, control science and system science and the like, the Markov model is introduced in the method to establish a passenger flow volume prediction model, and the AP having the least time consumption and the best quality of service is automatically switched in combination with the intelligent scheduling technology, a strict mathematical model is established, and senseless internet experience of users is realized.

Description

technical field [0001] The invention relates to the field of wireless network intelligent authentication, in particular to a Markov model-based multi-AP self-adaptive switching method. Background technique [0002] In recent years, with the rapid popularization of smart mobile terminals represented by smart phones and tablet computers, it has increasingly become a daily habit for people to browse web pages, install and use application software through mobile smart terminals. Although 3G and 4G technologies provide large-coverage mobile Internet access, users are worried about traffic and cost overruns. At the same time, WiFi modules have become the standard configuration of mobile smart terminals, making WiFi the most cost-effective wireless Internet access technology. WiFi is specially designed for medium and short-distance wireless communication, and its communication distance is generally below 100m. So in order to cover a relatively large area, we must deploy a large nu...
