摘要/Abstract

摘要：无线传感器网络中进行数据采集及其运算时均采用电池驱动，能耗便成了无线传感器网络设计时最应考虑的关键因素.采用网络编码时，中间节点发送的数据包是其接收信息的线性组合，传输一定大小数据包时最小化数据传输次数，传输次数越少，功率消耗也越少.分析了网络编码时无线传感器网络传输过程及其节能的原理，比较了是否采用网络编码的2种无线传感器网络传输方式的能效.结果表明，采用网络编码技术，可以有效地减少传输总功率，延长无线传感器网络的生存时间.

关键词： 无线传感器网络, 网络编码, 功率最小化, 能效

Abstract: Wireless sensor networks are often driven by batteries when they are used in gathering data or ubiquitous computing.Therefore,energy consumption is the key issue in designing wireless sensor network system.When network coding is applied,intermediate nodes may send out data packets that are linear by minimizing the number of transmissions required to communicate a given amount of information across the wireless sensor networks.The less the number of transmissions is,the less the energy consumption will be.The transmission process and the principle of saving energy in wireless sensor networks based on network coding are analyzed,and the energy efficienly of the proposed solution using network coding is compared with non-network coding solution.The results show that the transmission power can be reduced efficiently by network coding,and it will benefit the lifetime of wireless sensor networks.

Key words: wireless sensor networks, network coding, power minimization, energy efficienly
