Deployment method of wireless sensor network nodes in urban comprehensive utility corridor

Abstract

The invention discloses a node deployment method of a wireless sensor network in an urban comprehensive pipe gallery. The method includes: from both ends of the pipe gallery to the center, equidistantly deploying super nodes in the length direction of the urban comprehensive pipe gallery, so as to realize the deployment of super nodes. The high-frequency working areas deployed in the urban comprehensive pipe gallery are arranged at equal intervals; on this basis, ordinary nodes are randomly deployed, so that the coverage holes of super nodes are covered by ordinary nodes. Further, 10% of ordinary nodes are selected as advanced nodes to be deployed to achieve multiple coverage. Through the node classification arrangement, the monitoring energy consumption in the integrated pipe gallery can be directly reflected, so that the average energy of the super nodes in the high-frequency working area is higher, which is more in line with the actual conditions of the pipe gallery. Effectively alleviate the energy hole problem caused by the deployment of a single node, balance the network energy consumption, and prolong the network life cycle.

Description

technical field [0001] The invention relates to the technical field of monitoring of urban comprehensive utility corridors, in particular to a deployment method of wireless sensor network nodes in urban comprehensive utility corridors. Background technique [0002] Today, more and more information and communication technologies are being integrated into smart cities. As a result, innovations such as Wireless Sensor Networks (WSN), Wireless Local Area Networks (WLAN), high-speed networks, and smartphones all play an important role in people's daily lives. In particular, wireless sensor networks are increasingly used in various fields, such as urban integrated utility corridors. [0003] The urban comprehensive pipe gallery, also known as the common ditch, mainly refers to the construction of a building under the urban roads that lays various municipal public pipelines such as electricity, information, water supply, heat and drainage in the same space. In order to achieve th...

Problems solved by technology

It can be seen that if a single sensor network node is used to cover the sensing area, to meet the requirements of effective collection and transmission of information in the entire monitoring area, the deployment of nodes must be uneven, resulting in a waste of node resources, and will also lead to wireless sensor network performance. Unbalanced consumption, prone to premature death of nodes, resulting in energy voids

[0007] Based on this, the wireless sensor network in the existing urban integrated utility corridor has serious energy holes and short service life
