基于延迟感知的 WSN 数据收集网络结构优化设计
OPTIMISED DESIGN OF WSN DATA COLLECTION NETWORK STRUCTURE BASED ON DELAYS AWARE
摘要
Abstract
In order to solve current problems such as big delay and energy consumption during data collection in wireless sensor network (WSN),in this paper we design the delay aware-based wireless sensors data collection network structure.We introduced the idea of tree structure and divided the sensor nodes of WSN into multiple single-layer clusters with different sizes,followed by constructing new network structures so as to improve its topological structure and to make the clusters fulfil data communication in an interleaved way,this significantly reduced the delay of data collection process.Then,we built the delay and energy consumption calculation model of text WSN data collection, and designed the formation algorithm of the presented networks structure with the help of Top-Down technology.By minimising the communication distance we optimised the energy consuming level of the data collection mechanism as discussed in the paper.Experimental results showed that compared with existing WSN data collection network structure,the proposed network structure could effectively reduce the delay in WSN data collection process,and was capable of maintaining the energy consumption of entire communication at a lower level.关键词
