Description

Technical Field

[0002] With the rapid development of fields such as the Internet of Things, Internet of Vehicles, Internet of Ships, and Internet of Flying Objects, edge computing technology has continuously made breakthroughs, and various interconnection services have extended to the edge, thereby increasing the scale and complexity of information systems, and bringing challenges to the organization and application of interconnection in edge environments.

[0003] In the current market, there are a large number of information devices in the edge environment for building various small and medium-sized information systems. However, the software and hardware resources of these devices are uneven, and their performance varies, some are even poor. At the same time, due to the influence of complex terrain, weather, etc. during the mobile process, the communication resources at the edge are limited and the connection is weak. The existing wireless communication connection state perception technology generally relies on periodic active detection to obtain the communication connection state with other nodes. At the same time, the weak connection due to communication limitations will lead to multiple confirmation retransmissions. Generally speaking, it has a relatively high bandwidth occupancy for the edge communication link.

[0004] Currently, there is no optimization method for wireless communication connection state perception under the conditions of high mobility and weak connection at the edge. Therefore, it has become an urgent need for the current information system construction to overall design under the conditions of high mobility at the edge, lightweight utilization of edge communication resources to perceive the wireless communication connection state, and support the efficient availability under weak connection of physical distribution and mutual perception of communication connection states between wireless communication systems, so as to reduce risks such as low efficiency of wireless communication connection state perception in distributed systems caused by limited edge communication resources.
