The invention provides an inter-node data association opportunistic routing forward coordination method and system. The method comprises the steps of on the basis of hop count from nodes to a sink node in a wireless sensor network, determining a plurality of node sets which are arranged according to a first sequence, and carrying out data forwarding on the node sets in sequence according to the first sequence; and for the node set on which data forwarding is carried out currently, on the basis of a rank of each first cache data matrix of each node in the node set, determining a plurality of second nodes which are arranged according to a second sequence, and carrying out data forwarding on the nodes in sequence according to the second sequence. The nodes with high data association degree are searched in a data opportunistic transmission process as relay forwarding nodes; continuous propagation of copies is inhabited in a relay forwarding coordination mode; network transmission reliability is improved through opportunistic routing; network practical transmission data volume is reduced in a data fusion mode; energy consumption of the wireless sensor network is reduced; and data transmission efficiency is improved.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of wireless sensor networks, in particular to a data association opportunistic routing and forwarding coordination method and system between nodes. Background technique [0002] Farmland wireless sensor network can conveniently and accurately obtain real-time environmental information of agricultural production, which has become a key technology to guide agricultural production and improve crop yield. Efficient collection of network monitoring data is a basic problem in the research of wireless sensor network (WSN). As an important part of network data collection and application, network routing protocol has a great impact on network performance. For the complex environment of farmland, there are characteristics such as time-varying wireless channels and unstable links, as well as problems such as low reliability of fixed path routing and high number of retransmissions under the probabi...
