基于遗传算法的Ad hoc路由协议优化 总被引:1,自引:0,他引:1
目前存在大量的Ad hoc网络路由协议,但是很少有研究对这些协议的最优性能进行过分析.通过对Ad hoc网络路由协议的分析,结合遗传算法的基本原理,对路由协议参数的全局优化配置提出一种启发式求解算法.该算法采用可变长编码,结合遗传算法的选择、交叉和变异操作,对路由协议的性能进行全局优化.在NS2平台上的仿真试验结果表明,优化后的路由协议性能比未优化之前提高30%. 相似文献

In the paper, we introduce chinese corpus tagging based on statistical language model (bi-gram model)and Huang-Yu‘s smoothing method. Especially, we also suggest a two-directions method based on statistical languagemodel, namely, we not only compute probability of P(CIW)(W= w1w2w3…. wm),but also compute probability of P(C |wnwn-1…… w1)-From our experience we can see it can enhance the accuracy of Chinese corpus tagging using this method of two directions comoutation. 相似文献
