Wireless network load balancing method for edge computing environment

Abstract

The invention relates to a wireless network load balancing method for an edge computing environment, and belongs to the technical field of communication. According to the invention, the method considers that different types of service terminals have different QoS requirements, in which the session type terminal requires low time delay, the interaction type terminal requires low packet loss rate, the flow type terminal requires high jitter requirement and the background type terminal requires high packet loss rate. For this case, according to the method, whether the AP is in an overload state or not is judged according to whether the AP network condition meets the service requirement or not; and the optimal AP is selected for the unsatisfied STA for association through a TOPSIS multi-attribute judgment algorithm, so that the load of the AP is reduced, the load balance is realized, and the utilization rate of the network bandwidth is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a wireless network load balancing method oriented to an edge computing environment. Background technique [0002] In recent years, with the popularization of portable terminals and the development of mobile Internet methods, network access parties using wifi have become more and more extensive. Nowadays, wifi networks cover many places such as offices, schools, substations, etc. Compared with wired networks, the usage of wifi networks is increasing year by year. [0003] In the traditional IEEE801.11 standard, STA access at the MAC layer only relies on RSSI (Received Signal Strength) as the judgment standard, and selects the AP with the largest RSSI around itself for access. This method results in large power and wide coverage. APs are heavily loaded, while APs with small coverage areas are lightly loaded. [0004] After the wireless device accesses the AP (Ac...
