Embodiment Construction

[0022] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings and embodiments, which cannot be used to limit the protection scope of the present invention.

[0023] Such as image 3 Shown network structure, the present invention comprises the following parts:

[0024] (1) Add a new proxy subnet or delete a proxy subnet: When adding a new proxy subnet, that is, when adding a static route that is not the subnet where the node is located, the IP destination address pointed to by the static route of the subnet and the The subnet mask is synchronously added to the subnet table that requires the physical address of the proxy node. To delete the proxy subnet, query the proxy subnet table according to the subnet IP to be deleted, and then perform the deletion operation. Then trigger the Broadcast Agent Subnet Advertisement message.

[0025] (2) Proxy subnet notificatio...

Abstract

The invention relates to the technical field of wireless communication, and provides a hierarchical routing-based cross-heterogeneous network seamless connecting method. The connecting method comprises the following steps: adding or deleting a proxy subnet; performing broadcasting announcement on the proxy subnet; querying the proxy subnet; performing proxy subnet response; managing the proxy subnet; performing local routing and packet forwarding. According to the hierarchical routing-based cross-heterogeneous network seamless connecting method, the communication between a mobile self-organizing network and a fixed network is realized through a link layer routing-based mobile self-organizing network and a network layer routing-based fixed network connecting method, so that the coverage rate of the fixed network is improved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a method for seamless connection across heterogeneous networks based on layered routing. Background technique [0002] Mobile ad hoc network is a multi-hop, temporary autonomous system composed of a group of mobile nodes with wireless transceivers. It is a distributed network that does not require network infrastructure. Each node in the network is in an equal position. Nodes that are not within the direct communication range can communicate through storage and forwarding of other nodes; nodes can join or leave the network at any time , and can move freely in the network. The mobile ad hoc network is flexible in networking, low in cost, has a completely autonomous operation mode, and can realize communication of any node anytime and anywhere. It has a wide range of application scenarios in military, disaster relief, large conferences and other fields. The integrati...
