The invention discloses a handover algorithm of a short-range wireless optical communication system, which is suitable for short-range wireless optical communication. Based on the visible light communication technology,the communication in conventional visible light communication network is achieved by the LED lighting equipment, and the LED lighting coverage limits the normal communication only in the coverage of a certain light intensity. In general scenarios, users are often in the mobile state, in different LED illumination coverage the continuity of communication is particularly important. The invention realizes the function of keeping communication when the user moves in the visible light communication scene, and the communication quality is reliably ensured based on the user terminal defining the acquisition rate of the acquired energy and setting the judgment rule facing the network access point AP.

The invention discloses a pre-ranking POS network selection method for group switching based on a business type, and the method aims at solving a problem of network selection in a heterogeneous wireless network environment during vertical group switching. According to different business types, the method achieves the pre-ranking of networks, and then employs a PSO algorithm to carry out network selection. The method gives full consideration to two aspects: network load balance and users' satisfaction. Compared with a conventional switching algorithm and a conventional time sequence algorithm, the method improves algorithm time consumption, access blocking rate and network load balance, and enables the users' satisfaction to be close to the optimal value.
