Embodiment Construction

[0038] Below in conjunction with specific embodiment, further illustrate the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.

[0039] Suppose the length of the square sensor network is a and the width is b (a≥b). For the convenience of discussion and without loss of generality, we study the square sensing area (a=b), such as figure 1 As shown, the convergence point is located at the center of the sensor network, which divides the sensor network into two areas: the circular area inscribed in the sensor network, namely figure 1 The circle with a brighter background in the center; the rest is the boundary area, that is, fig...

Abstract

The invention discloses a mobile data collecting method based on rail assistance in a wireless sensor network. The method comprises a first step of dividing a square sensor network into two parts comprising a circular region internally tangent to the sensor network and the rest border regions, wherein a plurality of concentric rails are arranged in the circular region, a mobile node is arranged on each rail for collecting the information of a sensing node in a mobile manner, a plurality of arc rails are arranged in the border regions, and a mobile node is arranged in each border region for collecting the information of the rest sensing nodes; and a second step of configuring two antennas including a first antenna A1 and a second antenna A2 for the mobile nodes, wherein the first antenna A1 is responsible for communicating with the sensing node in a sensing region, and the second antenna A2 is responsible for communicating with other mobile nodes. According to the method disclosed by the invention, data collection can be completed without waiting the mobile nodes to move to a convergent point, so that the mobile collection time is greatly shortened, the energy consumption of sensor network nodes can be reduced, and the data collection time delay is effectively reduced.

Description

technical field [0001] The invention relates to a data transmission method used in a wireless sensor network area based on orbital coverage, specifically designs a data transmission method supporting mobile nodes to collect data, and belongs to the technical field of network communication. Background technique [0002] Currently, wireless sensor network data collection is mainly done in two ways: [0003] 1) Data collection based on stationary sensor nodes. In the multi-hop Ad hoc network organized by stationary sensor nodes, data transmission is carried out through multi-hop data relay between stationary nodes, and the data is finally aggregated to the aggregation point. Although the data delay of this method is relatively short, its disadvantages are also very prominent, that is, the energy consumption of relay nodes is large, and energy consumption hotspots are easy to form near the convergence point, the energy consumption of the network is uneven, and nodes with too fa...
