Topology control system and control method for dynamic network

Abstract

The invention discloses a topology control system and a corresponding topology control method suitable for dynamic networks, which mainly solve the problem of performance degradation when the existing network topology control systems and methods are used in dynamic networks, including a perception module and a data processing module , a data judging module, a communication module and a central module. The sensing module, data judging module, and communication module are respectively connected to the data processing module by wire, and the communication module is connected to the central module wirelessly; the sensing module collects the data of surrounding nodes, transmits them to the data processing module for caching, and selects the cluster head of the current node according to the data. It is transmitted to the data judgment module; after the data judgment module checks that the cluster head is qualified, the communication module is responsible for wirelessly transmitting the cluster head information to the central module; the central module summarizes the data of all nodes in the network and transmits the result to the client. The invention can improve the stability of the dynamic network and can be used for topology control of the dynamic network.

Description

technical field [0001] The invention belongs to the technical field of communication, and further relates to a node topology control system and method, which can be used in a dynamic network formed by mobile nodes. Background technique [0002] The Ad-Hoc network is a network connection established by dozens or hundreds of nodes equipped with sensing devices, computing devices, and communication devices through wireless communication. It is a network that can quickly deploy applications without pre-establishing fixed infrastructure. system. In the Ad-Hoc network, nodes cooperate with each other, and each node selects neighbor nodes within its communication range to establish a connection, and forms a network that meets connectivity through network clustering, multi-hop transmission, and other means. [0003] For the Ad-Hoc network composed of nodes such as automobiles, ships, and drones, the high-speed movement of nodes may cause the connected nodes in the network to leave ...

Problems solved by technology

For a topology control system with a centralized architecture, the central node of the network needs to run a highly complex algorithm, and is almost entirely responsible for the maintenance and update of the entire network, which causes the center of the network to bear a huge load, and With the continuous expansion of the network scale, the computing load and communication load of the central node are increasing rapidly, which is not conducive to the load balancing and scalability of the network.

In addition, once the central node encounters interference or damage, all nodes in the network will not be able to work normally, thus causing the paralysis of the entire network and reducing the robustness and anti-interference ability of the network

For the topology control system with distributed architecture, the network can achieve load balancing and has high robustness, but the nodes in the network work independently and cannot cooperate well and efficiently, which brings great challenges to the data fusion and unified scheduling of the network. big difficulty
