Method and device for layout mobile radio sensor network node based on virtual force

Abstract

The method comprises: estimating the direction and distance that the sensor node should be moved by calculating the size and direction of virtual force loaded by each sensor node; driving the sensor node to make relevant movement until reaching a force-balanced point-namely realizing a distribution of sensor network node. By the invention, the sensor nodes can automatically move according to its located geographical environment.

Description

technical field [0001] The invention relates to the field of wireless sensor networks, in particular to a node layout method and device for a mobile wireless sensor network based on virtual force. Background technique [0002] Wireless sensor network is an emerging hot technology, which has been highly valued by industry and academia in recent years. In a wireless sensor network, it usually includes M sink nodes and N mobile wireless sensor nodes, M and N are positive integers respectively, between M sink nodes, between N mobile wireless sensor nodes, and between M sink nodes and N mobile The wireless sensor nodes are connected through the wireless network. [0003] Sensor network layout is a basic issue in the field of sensor networks, which will directly affect the performance and life cycle of sensor networks. However, since the sensor network often works in an unknown, complex or even hostile environment, its layout is almost impossible to complete manually. Therefore,...

Problems solved by technology

[0009] These methods have achieved certain results, but as far as the current research progress is concerned, there is no layout method that comprehensively considers the influence of the position of the target to be detected, the obstacle terrain, and the location of the hotspot area to be detected on the sensor layout.

This obvious deficiency greatly limits the application range and application effect of these methods.
