摘　　要：无线传感器网络代码更新协议和路由协议都有着低能量、高通信效率等相似的特征,但也在通信方向、可靠性要求、维护策略方面存在着一些显著的差别;在研究目前已经存在的无线传感器网络代码更新协议的基础上,先提出了无线传感器网络代码更新所面临的挑战,然后从能量、存储空间、通信方式、算法、通信控制等方面总结了代码更新协议的特征,并对不同的更新协议相关项进行了比较,最后指出了代码更新协议的研究思路以及未来的发展趋势。Compared with routing protocols, code update protocols have notable difference in communications direction, reliability necessary, maintenance strategy in WSN, although they also have many similar characters, such as low energy, high communications efficiency. Based on the research about recent code update protocols, this paper first outlined to the challenge in front of code update protocols, following summarized the characters of code update protocols and compared some important features with them each other in the way of energy , stor age , communications way, arithmetic, communications control and so on. Finally, it pointed out the future research strategies and trends.
