Wireless Sensor Network Node Deployment And Coverage Simulation System

The wireless sensor network senses and collects the information that users need in the target area through sensor nodes.In order to accurately obtain the information required by users in the target area and meet the network coverage requirements,a large number of sensor nodes need to be deployed.However,a large number of sensor nodes in the target area often cause coverage vulnerabilities due to energy consumption or non-human factors.Vulnerability detection and repair algorithms need to be simulated in different target areas.Therefore,it is necessary to develop a support to view the deployment of nodes in different target areas.And node operation simulation experiment platform.This thesis combines simulation functions,terrain visualization and sensor node coverage and deployment algorithms and other related technologies to develop an interactive wireless sensor network node deployment and coverage simulation experiment system.In this system,researchers can deploy sensor nodes and node operations in the target area according to the experimental needs The specific work content is as follows:(1)Achieve wireless sensor network coverage and deployment in a given target area.The system can realize the deployment of sensor nodes on a given target area such as a rectangle,a circle,a sinusoidal surface,a peak surface,a saddle surface,or a three-dimensional surface with a function to be determined.In addition,the system can also simulate the deployment of sensor nodes on the mountain by approximating its three-dimensional surface graphics based on a single mountain photo.(2)The location operation of nodes is changed according to different quality of service requirements in network coverage.In the simulation experiment of sensor networks,boundary nodes can be set up for coverage vulnerability detection research,add nodes to judge the location and area of coverage vulnerabilities,or delete nodes to study coverage vulnerabilities and redundant nodes.
