Problems solved by technology

However, in WSAN, the sensor nodes are static, and the closer the sensor nodes are to the actuator nodes, the more data forwarding tasks they carry, so the energy consumption of the nodes is faster, which further makes the network die prematurely due to the energy hole of the nodes.

Embodiment Construction

[0057] The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention. The present invention is a sensor-actuator-oriented collaborative sensor execution network node data collection method, which mainly includes the following three steps:

[0058] 1 node mobile judgment

[0059] 1.1 Intra-cluster partition of network model

[0060] In order to facilitate the analysis of the communication characteristics of network nodes, an actuator node cluster can be divided into n ring-shaped areas, where R cluster is the maximum radius of the cluster, and R is the maximum communication distance of sensor nodes. Sensor nodes are distributed in different areas, such as figure 1 shown. The area closest to the center of the circle is the first area, and the next closest area is the second area, until the nth area...

Abstract

The invention provides a WSAN data collection method based on a bee colony algorithm. A technical scheme used is a WSAN node data collection algorithm oriented to sensor-actor collaboration, and an implementation process comprises establishing a cluster partition model, determining whether an actor node changes a data collection residing site or not according to energy consumption conditions of network related nodes, simultaneously introducing an inducing factor to determine a moving direction of the actor node, and solving an optimal residing position through an artificial bee colony (ABC) algorithm. Finally, a proxy node is selected according to a node load quantization parameter value to be used as a temporary data storage terminal, and a data sending rate of the nodes in the network is adjusted adaptively. Compared with the prior art, the method provided by the invention effectively balances energy of the nodes in the WSAN, improves stability of the network, and promotes comprehensive utilization efficiency of network resource.

Description

technical field [0001] The present invention relates to the technical field of wireless sensor execution network, in particular to a data collection method of wireless sensor execution network oriented to node cooperation. Background technique [0002] Due to its ubiquitous characteristics, Wireless Sensor Actuation Network (WSAN) is gradually being widely used in environmental monitoring, smart home, military monitoring and other fields. Due to the mobility of executor nodes in WSAN, the process of monitoring data collection becomes more flexible and scalable, and the energy of executor nodes is more sufficient, which can be used as a fixed cluster head for data transmission, avoiding the frequent replacement of cluster heads in the network. resulting in energy consumption. However, in WSAN, the sensor nodes are static, and the closer the sensor nodes are to the actuator nodes, the more data forwarding tasks they carry, so the energy consumption of the nodes is faster, whi...
