《计算机程序设计艺术》重译自Donald E. Knuth(汉名高德纳)的三卷著作： The Art of Computer Programming: 1. Fundamental Algorithms 2. Seminumerical Algorithms 3. Sorting and Searching ；三卷中文名为《基本算法》、《半数值算法》及《排序与查找》。本书内容博大精深，作者因为三卷书获得美国计算机协会1974年图灵奖（该奖被国际公认为计算机科学领域的最高奖项）。(The Art of Computer Programming retranslation Donald e. Knuth (han gartner) three volumes of The book: The Art of Computer Programming: 1. The Fundamental Algorithms 2. The Seminumerical Algorithms 3. The Sorting and Searching Three volumes in Chinese, the basic algorithm, a numerical algorithm and the sorting and searching.And profound content of the book, the author for three books for the computer association in 1974 Turing award (the prize is internationally recognized as the highest award in the field of computer science).)

heed分簇算法，基于剩余能量，地理位置合理选择簇头，使能量均衡，防止出现能量空洞，延长网络生命周期(heed clustering algorithm, a reasonable choice based on the remaining energy cluster head, geographical location, the energy balance, to prevent the energy hole and prolong the network life cycle )
