Method for polling long distance wireless multi-hop data facing transparent transmission equipment

Abstract

The invention discloses a long-distance wireless multi-hop data polling method for transparent transmission equipment, which is realized by a wireless multi-hop data polling network consisting of data aggregation nodes and data transmission nodes. The data transmission nodes are accessed to the prior data polling network through a neighbor discovery protocol. The data aggregation nodes poll the data transmission nodes through a multi-hop data polling protocol sequentially, namely the data aggregate nodes send data requests to the destination data transmission nodes, and the data transmission nodes, and send data response packets to the data aggregate nodes after receiving data request packets. The data request packets and the data response packets are transmitted to destination nodes by a plurality of relay nodes in a link layer. In the data polling network, nodes acquire link quality information of the surrounding neighbor nodes through link quality estimation and send the link quality information to the data aggregate nodes. The data aggregate node can calculate the best route for each data polling through aggregated link quality information.

Description

technical field [0001] The invention relates to a computer network data collection method, in particular to a long-distance wireless multi-hop data polling method for transparent transmission equipment. Background technique [0002] Transparent transmission equipment is a kind of wireless communication equipment that is widely used, and it has the advantages of simple use and convenient transmission. However, since the transparent transmission device cannot obtain signal strength when receiving data, and the communication distance between single-hop transparent transmission devices is also very limited. Most of the existing polling protocols for transparent transmission equipment can only be applied to simple single-hop data polling from point to point. However, when data needs to be transmitted over a long distance, the single-hop data polling protocol cannot meet the requirements of data transmission. [0003] Ad hoc multi-hop network protocols like AODV and DSR can prov...

AI Technical Summary

Problems solved by technology

Routing search will generate a large number of broadcast request packets, and the whole process is relatively slow, and the traffic load of the network is also relatively large

At the same time, such protocols must rely on hardware features such as channel collision detection and channel quality estimation, but transparent transmission equipment cannot provide such services
