摘要
在移动通信快速发展的今天,移动计算环境下的位置管理已经成为公认的最重要和最具挑战的问题之一。文章提出了一种新的位置区设计方案,对一个区域内大量移动用户的运动特点和通信情况分类进行位置区的模糊化设计,并通过模糊化建模和MATLAB仿真实现,分析了移动用户速度和会话到达率等因素对位置区设计的影响,给出了一种移动计算环境下位置区的模糊化设计方法,优化了网络的整体管理。
Today,as far as we know,location management in mobile computing environment is generally acknowledged one of the most important and challenging problems.This paper puts forward a new fuzzy design method of location area for a large number of mobile subscribers that have different move characteristics and communication situations,then analyzes the influences of the speed and calling arrival rate on the design of location area through fuzzy modeling and simulation,finally realizes the fuzzy design method of location area by MATLAB simulation tool under the wireless communication environment.
