Triangulation-based data transmission system and transmission method for sensor networks

Abstract

The invention relates to the wireless communication filed, discloses a triangulation-based data transmission system and a method for sensor networks, and solves problems of data transmission of the sensor networks that network stabilization between nodes is poor, quality of service (QoS) of links cannot be satisfied, and calculation of the nodes is complex in the prior art. The data transmission system comprises a neighbor node information collecting module, a data processing module and a data transmitting module, wherein the neighbor node information collecting module is used for collecting hello packets cyclically broadcast by neighbor nodes and including the neighbor node information, forming an information table of the neighbor nodes, and updating the information table of the neighbor nodes by monitoring statuses of the neighbor nodes; the data processing module is used for constructing a geometric space module between the nodes and the neighbor nodes through triangulation, forming a data transmission route between the nodes, and updating the triangulation to form a new data transmission route when the information table of the neighbor nodes changes; and the data transmission module is used for data transmission and management according to the data transmission route between the nodes. The triangulation-based data transmission system and the method for the sensor networks are suitable for data transmission under influence of the node movement factor.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a sensor network data transmission system and transmission method based on triangulation in the field of wireless communication. Background technique [0002] The sensor network is a wireless network composed of randomly distributed tiny nodes integrated with sensors, data processing units and communication units through self-organization. The sensor network has the characteristics of large-scale, self-organizing, dynamic, data-centric and application-driven. It measures signals such as heat, infrared, sonar, radar, and seismic waves in the surrounding environment through built-in sensors in the node, thereby detecting temperature, humidity, noise, light intensity, pressure, soil composition, size, speed, and direction of moving objects Real-time data collection, supervision and control, information sharing and storage management and other functions. It greatly expands the...
