摘要: 本文针对无线物联网能量有限的应用场景,提出一种基于网络编码的能量受限数据传输机制NCDT.NCDT引入传染病路由的思想,对网络编码数据包的传输方式进行建模.通过限制编码数据包在网络中的复制次数,以及参与数据包交换的移动终端数量,控制网络的整体能量消耗.NCDT机制在限制网络编码资源消耗的同时,保证了在传输过程中取得较高的传输可靠性.

关键词: 网络编码, 物联网, 能量

Abstract: A network coding based energy constrained data transmission mechanism NCDT is proposed in this paper for limited energy scenario in wireless internet of things.NCDT makes use of epidemic routing to construct mathematical model to describe transmission process of coding packets.NCDT controls overall energy overhead through constraining duplication time of coding packets and the number of terminals that exchange packets.While constraining resource consumption,NCDT maintains high transmission reliability.

Key words: network coding, internet of things, energy
