Problems solved by technology

First, it takes a long time to construct the routing structure. The experiment found that when the number of nodes increases to 40, more than 20% of the network cannot find the routing structure within 2 hours, which greatly limits the practicability of the method
The second is that it does not consider the operation mode of the method in practical applications, such as how to estimate the initial power and collect and distribute routing decisions, etc.

Embodiment example

[0083] The effect of the present invention can be further illustrated by the following simulation experiments. The sensor network contains 41 nodes, one of which is a sink node. The connecting edges between nodes are randomly generated as follows: the nodes are evenly distributed in a 100×100 square area, and the two nodes can communicate when the distance between them does not exceed 20m. The remaining energy of the node is evenly distributed within 1~10 joules, and the energy consumption of receiving and sending a data packet is 3.33×10 respectively -4 Jiaohe 6.66×10 -4 Coke. Randomly generate 50 network instances. Compare the present invention with the existing graph decomposition scheme.

[0084] figure 2 In order to simulate the time-consuming comparison results of the present invention and the existing method in the experiment, if a method takes more than 7200 seconds (2 hours), the operation of the method is forcibly terminated. Therefore, the existing method is in 10 ...

Abstract

The invention discloses a data collection method for an energy heterogeneous wireless sensor network, which includes the following steps: (1) establishing a corresponding relationship between voltage and power in the network measurement stage, and then collecting voltage information of sensor nodes through an initial routing tree to estimate the power, At the same time, the neighbor information of nodes is collected to construct the network topology. (2) In the network decomposition stage, the network is divided into 2-connected sub-networks according to the topology information. (3) In the subnetwork solution stage, the routing structure of the subnetwork is found by establishing an integer linear programming problem. (4) The route distribution stage distributes the routing structure to the network, and the node updates the routing structure to send data to the sink node. The invention can be used in sensor networks with different remaining power of nodes, and can quickly build a routing structure with the longest survival time.

Description

Technical field [0001] The invention belongs to the technical field of wireless networks, is a method for transmitting information in a wireless sensor network, and specifically relates to a data collection method for an energy heterogeneous wireless sensor network. Background technique [0002] One of the main applications of wireless sensor networks is to monitor environmental conditions and periodically send the monitored data to the sink node. For example, when applied to ecological environment monitoring or building quality monitoring, sensor nodes need to periodically collect designated Data, and then transmit the data to the sink node in some way for subsequent processing. Optional transmission methods include tree structure and mesh structure. In the tree structure, each node needs to send data to the parent node, and the flow of data is a tree rooted at the sink node, called a routing tree. In a mesh structure, each node can send data to different nodes. Because the r...
