Abstract

The invention relates to a non-uniform clustering routing method suitable for a subway tunnel. The method is applied to aggregation nodes and sensor nodes arranged on the inner wall of the subway tunnel. The method specifically comprises the following steps: establishing a tunnel three-dimensional space model; performing network initialization based on fixed nodes; performing clustering formation based on node remaining energy and node positions; and establishing inter-cluster multi-hop routing based on network quality of service (QoS), the node remaining energy and the node positions. Compared with the prior art, the non-uniform clustering routing method has the advantages that non-uniform clustering is finished by adopting a cluster head competition algorithm based on the node remaining energy and a cluster radius, and a cluster structure, the node remaining energy and a link bit error rate are considered comprehensively so as to optimize a multi-hop path in a super-long line.

Description

technical field [0001] The invention relates to a wireless network routing method, in particular to a non-uniform clustering routing method suitable for subway tunnels. Background technique [0002] In the tunnel structure monitoring application, the position of the sensor nodes is determined by the monitoring task, and they are arranged on the inner ring wall of the long linear tunnel. These have directly affected the topological structure of the wireless sensor network, making it have the characteristics of long line and distributed. [0003] The low-energy adaptive clustering routing algorithm LEACH (Low-Energy Adaptive Clustering Hierarchy) proposed by Heinzelman W R of the Massachusetts Institute of Technology is the basis of most subsequent clustering routing algorithms. The LEACH algorithm introduces the concept of "round", and each round includes an initialization phase and a stable transmission phase. In the initialization stage, a cluster head is randomly formed,...
