Embodiment Construction

[0034] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0035] Such as figure 1 As shown, the new node network access method of the wireless multi-hop cooperative network provided by this embodiment includes the following steps:

[0036] S1. The nodes on the network periodically broadcast the MSH-NCFG message, and the MSH-NCFG message may be embedded with the MSH-NENT message.

[0037] S2. The new node performs network access scanning and pre-selection operations, specifically:

[0038] S2.1. Start a new node and continue to scan the network. If the MSH-NCFG message is not re...

Abstract

The invention discloses a cooperative relay network access method for a wireless multi-hop cooperative network. The method comprises the following steps of periodically broadcasting an MSH-NCFG message at a network node; after a new node is started, continuously carrying out network access scanning, if the MSH-NCFG message can be received, establishing a physical neighbor list, recording information of neighbor nodes, and after scanning is completed, selecting a plurality of pre-selected sponsored nodes and pre-selected access relay nodes from each neighbor node, and then broadcasting an MSH-NENT message carrying the information of each pre-selected sponsored node to each neighbor node in the physical neighbor list; after the network node receives the MSH-NCFG message, parsing an MSH-NENTdata packet embedded into the message, if the MSH-NENT data packet exists, judging whether the node is selected as the pre-selected sponsored node or pre-selected access relay node by the new node, and respectively deciding whether to reply a sponsorship agreement message or to forward the MSH-NENT message to the new node according to a judgment result; and making the new node wait for the MSH-NCFG message from the pre-selected sponsored node in order to decide whether a network access process is completed.

Description

technical field [0001] The invention relates to the technical field of wireless communication. More specifically, it relates to a cooperative relay network access method of a wireless multi-hop cooperative network. Background technique [0002] Network construction is the primary function of wireless multi-hop cooperative network. Network construction starts from the establishment of connections between nodes, first realizes the synchronization between nodes, and then gradually realizes the synchronization of the entire network. [0003] The network construction process of the wireless multi-hop cooperative network is completed through the interaction of two management messages, MSH-NCFG message (network configuration message) and MSH-NENT message (network access message) between nodes. The on-net node that is connected to the network sends the MSH-NENT message, and the MSH-NENT message is sent by a new node that is not connected to the network. During the two kinds of me...
