Ant routing use Swarm-Intelligence for route discovery and also have multi-paths for backup and balance. However, the efficiency of ant routing can more and more go down in large-scale mobile ad hoc networks. For solving such condition, improving the efficiency of ant routing, this research proposes the algorithm that combines both the GRID and ant routing, called grid-based ant routing algorithm. GARA can improve efficiency of ant routing in large-scale mobile ad hoc networks.

对於解决路由上的一些问题,也因此有各种不同类别的路由方法被探讨,蚂蚁路由演算法利用群体智慧(swarm-intelligence)找寻路径,而且同时能够找到多条备援路径,但是,蚂蚁路由演算法会因为行动主机数目愈来愈多情况下,而导致路由演算法效率降低,因此本论文以GRID为概念,融入蚂蚁演算法中,让蚂蚁是采用网格对网格(grid-by-grid)方式传输,改善蚂蚁路由演算法在行动主机数目愈来愈多情况下的效率与效能。

Data pre-processing technologies such as singular points elimination, registration and radius compensation are studied.

First, the character clustering algorithm regards the character as our features and then it can cluster these sentences of our target words to the correct group without any other resources. The average precision is 66.1%. Second, in the concept clustering algorithm of the aggregate computing, we use HowNet as the knowledge base of our feature words and obtain the concepts of these words. We cluster the sentences which have the same or similar concepts of the feature words into the same group. And then we can complement some lacks of the character clustering algorithm. The average precision is 72.3%. Third, regarding the concept clustering algorithm of the sememe distance, we use the sememe distance to compute its concept similarity. It improved similarity measure of the concept clustering algorithm of the aggregate computing. It achieves 81% average precision and gets better cluster quality.

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子:"据报道,美国利用转基因技术,将一种病毒的DNA分离出来,与另外一种DNA进行结合,拼结成一种剧毒的"热毒素"生物战剂,且私下有人透露,这种生物战剂只需20克,就可以导致全球60亿人全部感染死亡。"
