Problems solved by technology

[0007] ①The path of the authentication request is too long, and the delay of authentication increases
[0008] ②There is too much information waiting for certification, the processing time is prolonged, and the timeliness of certification is negatively affected
[0009] ③ The authentication node is not equal to other nodes. When the authentication node has a problem, it cannot be replaced by other nodes, which causes the problem of poor network invulnerability
[0010] (2) Equipment performance is not eq

Embodiment Construction

[0061] A wireless self-organizing network distributed authentication multi-layer tree routing method is characterized in that it includes a group generation process, a group routing maintenance process and a group routing selection process;

[0062] The generation process of the group, that is, the wireless ad hoc network distributed authentication multi-layer tree routing generation process, adopts the following steps:

[0063] Step 1 Initial identity authentication process. Naturally distributed nodes that contain all node authentication information send authentication information packets in a broadcast manner. Nodes that have authenticated each other add each other to the neighbor table and become "neighbor nodes" with each other. All nodes complete mutual authentication and form their own neighbor table according to this process.

[0064] Step 2 determines the cluster leader of the highest level cluster. The highest-level group leader can manually set the designation or...

Abstract

The disclosed multilayer tree route method for distributive certification of wireless self-organizing network comprises the group generation, route group maintenance and group selection. The key of this invention is to reconstruct the network structure into a multilayer group tree topology. This invention improves certification efficiency, reduces network spending, and improves the network security and reliability.

Description

Technical field [0001] The invention belongs to the field of wireless ad hoc network technology, such as wireless ad hoc network, wireless local area network, wireless access, etc., and in particular relates to a wireless ad hoc network distributed authentication multi-layer tree routing method. Background technique [0002] Mobile Ad Hoc Network (hereinafter referred to as MANET) is a technology different from traditional cellular wireless communication networks. The traditional cellular wireless communication network requires the support of fixed network devices such as wireless access points (hereinafter referred to as APs) and base stations when performing service control such as data forwarding and authentication. The wireless self-organizing network (MANET) does not need the support of fixed network equipment, and each node can form a network by itself through negotiation. During communication, the node communicates directly with the nodes within its wireless coverage...
