Abstract

The invention discloses a wireless ad hoc network construction method and a wireless ad hoc network data transmission method. After the construction method is powered on, the construction of the network is realized according to the networking frame broadcast by the central node, and each node is based on the received networking frame. The frame determines the level, thus forming a multi-level wireless network. The entire wireless network is completed by itself during the construction process, realizing the self-organization of the wireless network; solving the problem that point-to-point direct wireless communication cannot be performed due to long distances, and ensuring the effective construction of the wireless network . The data transmission method provided by the present invention guarantees the effective delivery of data transmission according to the hierarchical forwarding mode; it not only solves the problem of data conflict caused by multi-node transmission data, but also if a certain node fails to forward, other nodes will Automatic forwarding will not affect data transmission and keep the network unblocked.

Description

technical field

[0001] The invention relates to a network construction method and a data transmission method, in particular to a wireless ad hoc network construction method and a wireless ad hoc network data transmission method. Background technique

[0002] The wireless ad hoc network protocol is a hot research direction at present. There are many large companies in the world doing research, and there are many routing methods researched, but most of them are too complicated and the simulation effect is good, but the effect in actual use is affected by the installation location, The strength of the signal has a greater impact, and the effect is not necessarily good.

[0003] For the currently popular wireless ad hoc network protocols such as Zigbee, the network capacity is large, up to 65535 nodes, and each node in the network needs to use a special zigbee chip or module, and ordinary FSK modulated wireless modules cannot be used. The cost of the wireless transceiver part i...

Embodiment Construction

[0023] The technical solutions claimed in the present application will be further described in detail in conjunction with specific implementation methods.

[0024] The technical solution claimed in this application is a method for constructing a wireless ad hoc network and a data transmission method for the wireless ad hoc network constructed based on the method.

[0025] Wherein the wireless ad hoc network construction method includes the following steps:

[0026] Step 1: After power-on, the central node gateway sends an initial networking frame with a level of 0 in the form of broadcast;

[0027] Step 2: After receiving the initial networking frame, the node located near the central node sets itself as level 1, and then sends out a networking frame with level information as 1 in the form of broadcast;

[0028] Step 3: After receiving the networking frame of level 1, the nodes in the network whose level is not set set their own level to 2, and then send out the networking fr...
