Abstract

The present invention discloses an adaptive and stable clustering method and system suitable for load balancing of highly dynamic wireless networks, wherein the method includes the following steps: S1. Calculate the cluster head competence of nodes according to the stable neighbor nodes, and thus Elect the optimal cluster head to form the initial cluster structure; S2. Adaptively maintain the cluster structure, including the maintenance of stable neighbor nodes, the storage and update of the standby follower node table, the change of cluster type, cluster fusion, cluster dissolution and multiple Maintenance of gateway node pairs. The present invention provides an adaptive and stable clustering method suitable for load balancing of highly dynamic wireless networks. Considering the impact of the clustering method on the three factors of clustering network connectivity, stability, and load balance, it can Density establishes a general and stable clustering structure in which multiple types of clusters coexist, making the clustering method applicable to various scenarios of large-scale traffic densities with uneven distribution of nodes.

Description

technical field

[0001] The invention relates to a highly dynamic wireless ad hoc network, in particular to an adaptive and stable clustering method and system suitable for load balancing of a highly dynamic wireless network. Background technique

[0002] Typical high dynamic wireless ad hoc networks mainly include vehicle ad hoc networks and UAV ad hoc networks, which are special ad hoc networks. Among them, VANETs (Vehicular ad hoc networks) is referred to as the Internet of Vehicles, which is the application of mobile ad hoc networks (MANET, Mobile ad hoc network) in the field of transportation. As an important part of the intelligent transportation system, VANETs provide vehicles with many applications for road safety, traffic management, and infotainment through communication between vehicles and between vehicles and infrastructure.

[0003] In mobile ad hoc networks, there are two types of network structures: planar structure and layered structure. In the planar struc...
