Low-power anchor node rotation method in mobile ad hoc networks

Abstract

The invention discloses a low-power anchor node rotation method in a mobile ad hoc network. The method comprises the following steps that step 1.all nodes collect own positions and residual energy information to an anchor node which is closest to a network center in the mobile ad hoc network which divides node roles. According to the method disclosed by the invention, when an anchor node rotation condition is evaluated, a distance condition between each user node and the associated anchor node is considered, so that a problem of high communication energy consumption caused by too large communication distance is avoided, and a comparison condition of average residual energy of the anchor nodes and the user nodes is also considered, when the energy consumption of the anchor nodes is larger, the anchor node rotation is carried out timely, so that the energy consumption fairness between the nodes is guaranteed, and furthermore, through considering the residual energy of each candidate node in a process of selecting a new anchor node, some nodes cannot be continuously taken as the anchor nodes, so that the energy consumption fairness between the nodes is further guaranteed.

Description

technical field [0001] The invention relates to an anchor node rotation method, in particular to a low-power consumption anchor node rotation method in a mobile ad hoc network. Background technique [0002] In recent years, mobile ad hoc networks have been widely used in many fields such as emergency services, post-disaster search and rescue, intelligent transportation, and factory automation due to their advantages of fast networking and no dependence on infrastructure. The hierarchical structure of the mobile ad hoc network refers to the role division of networking nodes (which can be personnel, robots, vehicles, etc., hereinafter referred to as nodes) in the network, so that nodes with different roles can improve the service of the network through cooperation. Quality, such as reducing the total energy consumption of nodes in the network and network communication load. The basic form of the layered structure in the mobile ad hoc network is a two-layer structure, and othe...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a low-power anchor node rotation method in a mobile ad-hoc network. The proposed method not only considers the relationship between each user node and the associated anchor node when evaluating the anchor node rotation conditions. distance, to avoid the problem of excessive communication energy consumption caused by the communication distance being too large, and considering the comparison of the average remaining energy between the anchor node and the user node, when the energy consumption of the anchor node is large, the anchor node rotation is carried out in time to ensure that the node energy fairness among
