Abstract

Within collaborative computing, computer mediated communications are evolving rapidly thanks to the development of new technologies. The facilitation of awareness and discovery of users in the communications networks is a key requirement for the success of these collaborative systems. Besides the need for location awareness, the emergence of heterogeneous wireless environments, where users can freely roam, is making Location Management (LM) an increasingly important topic for network operators. In this paper, we use a general model for LM signaling costs to obtain analytical expressions for their optimization. These expressions are applicable to different LM algorithms and scenarios, contributing towards the development of a standardized performance evaluation technique and to deliver guidelines for the optimum design of Location Areas (LAs). We also illustrate how modifications in the different parameters involved in the LM costs affect the optimum number of cells per LA and the value of the optimum LM costs.
区位管理成本统一分析模型与区位区域优化设计
在协作计算中,由于新技术的发展,以计算机为媒介的通信正在迅速发展。促进通信网络中用户的认识和发现是这些协作系统成功的关键要求。除了对位置感知的需求外,用户可以自由漫游的异构无线环境的出现,使得位置管理(LM)成为网络运营商日益重要的话题。本文利用LM信号成本的一般模型,得到其优化的解析表达式。这些表达式适用于不同的LM算法和场景,有助于标准化性能评估技术的发展,并为位置区域(LAs)的优化设计提供指导。我们还说明了LM成本中涉及的不同参数的修改如何影响每个LA的最佳单元数和最佳LM成本的值。
