Embodiment Construction

[0075] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0076] The generation and maintenance method of the virtual backbone network in the mobile ad hoc network of the present invention, its key points are:

[0077] 1. Establish a partitioned and hierarchical virtual backbone network routing topology: the network will be divided into several areas, and each area has a regional virtual backbone network, which is connected through area border nodes. All the data of the node will be sent to the neighboring virtual backbone network nodes for unified routing, forming a two-layer routing structure of ordinary nodes and regional virtual backbone networks, which can meet the networking needs of large-scale networks.

[0078] 2. Establis...

Abstract

The invention relates to the technical field of computer networks, and discloses a method for generating and maintaining a virtual backbone network in mobile adhoe networking. The method comprises the following steps: S1, under the control of a timer, a node u carries out environment perception on exchange state information among neighbor nodes of the node u, selects an initial cluster and declares respective regions; S2, each node selects a neighbor node with highest priority as an access node, continuously adds the access node into different regions, and constructs a region virtual framework network using the initial cluster as a center in a distributed manner; and S3, constructing a global virtual framework network by selecting a boundary gateway node to be communicated with the adjacent region virtual framework network. According to the invention, the problems of low efficiency and instable data routing under dynamic topology of a flooding route mode can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method for generating and maintaining a virtual backbone network in a mobile ad hoc network. Background technique [0002] The rapid development of microelectronics, chips and information communication technology has gradually brought human beings into the ubiquitous network era. The ubiquitous network era has brought great changes to the edge of the network. More and more devices, including various network terminals, smart home appliances, sensor devices, vehicle-mounted devices, wearable devices, etc., can be interconnected through a variety of wired or wireless methods. , into the daily life of users. [0003] As a data network composed of dozens, hundreds, or even thousands of terminal nodes, the mobile ad hoc network adopts wireless communication and can dynamically form a network and communicate at any time without a fixed base station. Environmental monitorin...
