Node arrangement method for improving link transmission reliability in chain wireless sensor network

The invention provides a node arrangement method for improving the link transmission reliability in a chain wireless sensor network. The method comprises the steps that a, wireless sensor nodes are connected in series, so that the sensor nodes and a wireless gateway form a wireless sensor chain network structure; b, chain network parameters of the wireless sensor are obtained; c, the maximum arrangement distance Lmax of the wireless sensor nodes is calculated; d, according to the wireless sensor node network parameters and the maximum arrangement distance Lmax, the wireless sensor nodes are arranged, and the arrangement distance of the wireless sensor nodes is not larger than the maximum arrangement distance Lmax of the wireless sensor nodes. As for the wireless chain network, the reliability of the wireless chain network can be effectively improved, the gap in the domestic wireless chain network research is filled, a method is provided for the application of the wireless chain network in the tubular environment and the like, and the reliability of wireless chain network transmission is ensured.
