Embodiment Construction

[0054] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0055] like figure 1 As shown, the system model based on the tunnel wireless sensor network includes a mobile car and several sensor nodes deployed in the tunnel environment to collect tunnel environment data. The car has the function of transmitting carrier signal and receiving data at the same time. In the model, the trolley passes through the sensor network periodically and at a constant speed along the track (dashed line AB in the figure) at a speed v to collect data sensed by sensor nodes in the area, and the track AB is long L.

[0056] Said method comprises the following steps:

[0057] Step 1: Use the discretization method to divide T into |T| equal time slots, and obtain a set of continuous time slots in which each sensor node can communicate with the car.

Abstract

The invention discloses a wireless sensor network data collection method based on a tunnel environment, and the method comprises the following steps: 1, arranging sensor nodes in the tunnel environment for collecting tunnel environment data, and collecting the data through a mobile trolley; dividing the moving period of the trolley into a plurality of time slots by using a discretization method, and obtaining a continuous time slot set in which each sensor node can communicate with the trolley; 2, for each time slot, calculating the throughput of all sensor nodes which can communicate with thetrolley in the time slot; and step 3, for each time slot, allocating the time slot to the sensor node with the maximum utility gain to obtain a time slot allocation scheme with the maximum total utility of the network. The backscatter communication technology is applied to the wireless sensor network based on the tunnel environment, the energy consumption can be reduced, the total network effectiveness can be maximized, the sensor network data collection quality is improved, and the fairness of the data collection proportion of each node is realized.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a tunnel environment-based wireless sensor network data collection method. Background technique [0002] In the currently deployed wireless sensor networks, the data sensed by sensor nodes is gathered to the data sink node in a multi-hop or single-hop manner through wireless communication. In the tunnel-based wireless sensor network, the sensor nodes are deployed in the tunnel to perceive the tunnel environment data. Furthermore, the built-in radio frequency module of the sensor generates radio frequency signals to wirelessly forward the sensed data. The radio frequency transmission consumes a lot of battery energy. In some specific tunnel scenarios, such as mines and underground oil pipelines. Moreover, in a wireless sensor network, the greater the node communication distance, the greater the power required for the node to transmit signals. After the node is deployed, th...
