Research And Application Of Deployment Optimization Of Wireless Sensor Network

Today,30%of energy consumption in our country is about building,witheconomic development and people’s living standards improve,the trend of energyconsumption on building growing is significant.To enhance the energy effect level,the running of building can be in energy saving status and to the implement theenergy saving state of building running, the status of running environment in buildingshould be acquired quickly.In application of building energy efficiency,the status ofenergy efficiency in a building can be concluded from the consumption of energy bythat building and some environment physical parameters such astemperature,humidity,wind speed,air pressure and so on.The monitoring of energyefficiency status is one of the important steps for energy efficiency evaluation.Because of the complexity of space structure and the deployment of wireless sensornetwork (WSN) can be implemented expediently, WSN can be used to constructbuilding running environment acquisition system effectively.Because it is not necessary to modify the existing structure of a building if aWSN is deployed in it to collect the running environment status of the building and itis not necessary to cable for commutation in the building if a WSN is deployed in it, itis very convenient if a building running environment acquisition system is based onWSN. Especially, if there is some special position where the sensor node is notsuitable to deploy for long time in a building, mobile sensor node can be deployed atthose positions for the acquisition of desired information. At the same time,inensuring complete acquisition target under the premise of buildingenvironment,reasonable deployment of wireless sensor network node.It can not onlyimprove the coverage of wireless sensor network monitoring,but also improvenetwork performance and greatly saving the cost.The purpose of this paper is to research on wireless sensor network deploymentoptimization and applications,in order to evalute the performance of optimizeddeployment scenarios,we studied the wireless sensor network simulation method inthe first place,and then simulate the wireless sensor network which use the CTPprotocol,three parameters to evaluate network performance through simulationresults,that cost,the average jump times and packet loss rate.Design networkperformance evaluation method base on network performance parameters;Network performance evaluation method as the fitness function,the sensor network deploymentoptimization problem modeling,using a genetic algorithm to optimize the deploymentproblem is solved to obtain an optimal deployment scenarios,analys the affect of theresults of the selected genetic parameters according to the experiments.Finally,we alsodesigned a information collection system of the building environment,the system cancollect the evaluation of building energy efficiency parameters of state of the builtenvironment such an temperature,humidity.Then test the reliability of the system,theresults show that the system can be effective applied to the information collection ofthe building environment.At the end of this article,analysis of experimental results,theactual deployment scenarios used in the information collection system will optimizecontrast optimized deployment scenarios of network performance is superior to theinitial deployment scenarios of network performance.
