An Improved Scheme for Partial Collection of Triggered Data in Large-scale Wireless Sensor Network
摘要
Abstract
In order to better resolve the problem of partial data collection in disaster scenarios of large-scale wireless sensor net-works,an improved triggered partial data collection scheme for large-scale wireless sensor network is presented.The proposed scheme uses the encoding packets among multiple segments of a single source node to record the collected disaster source data and the walk packets to achieve data encoding,which can not only enhance the reliability of the collected data,but also can ef-fectively reduce the energy consumption of the source node.At the same time,a dynamic division of coding unit scheme is pro-posed to optimize the node storage space strategy.Based on the information exchange between neighboring nodes,the size of the coding unit that divides the collected source data is dynamically adjusted.Then for the data collection examples of large-scale wireless sensor network in disaster environments,a dynamically adjustable coding redundancy scheme that can sense dan-gers is proposed,so that the coding redundancy can be dynamically increased to effectively promote the data recovery rate.关键词
