Wireless ad hoc network construction method and wireless ad hoc network data transmission method

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...

Problems solved by technology

The principle of forwarding is to forward as little as possible. Too much forwarding will cause too much data to be transmitted in the network, resulting in communication congestion and network deterioration; too little forwarding will cause the signal to be unable to be reliably transmitted from the source node to the destination node.

The number of forwarding times can be entered manually. For example, when the range is large, set a larger number of forwarding times, and set a smaller number of forwarding times. This is called artificial networking. The number of times is enough, and the farthest node can also communicate with the central node. The disadvantage is that the number of forwarding times is not easy to determine, and the number of forwarding times of each node in the network should not be the same, because the distance between each node and the central node is different. , the closer the distance, the less the number of reposts, and vice versa.
