Abstract

Although wireless networks have experienced tremendous improvements, mobility management remains an issue in a context of massive deployment of small cells, especially in the context of Internet of things and future 5G networks. In this paper, using the Identificator and locator Split concept, we propose a local anchor based network architecture for mobility support in dense small cells networks, where the local domain is partitioned into several location service areas (LSA). We developed a mathematical framework to analyse the performance of the proposed scheme and Markov models are used to obtain the close form expression of the intra-LSA and inter-LSA handover parameters. Numerical results show that the proposed scheme achieve up to 38% and 21% of signaling cost saving per mobile node for the intra-LSA and inter-LSA handovers respectively (K=3), compared to the existing LISP-MN protocol.
基于本地锚的识别器定位器分离网络移动支持体系结构
尽管无线网络经历了巨大的进步,但在大规模部署小型基站的背景下,尤其是在物联网和未来5G网络的背景下,移动性管理仍然是一个问题。本文利用标识符和定位器分离的概念,提出了一种基于本地锚的网络架构,用于密集小蜂窝网络中的移动性支持,其中本地域被划分为多个位置服务区(LSA)。我们开发了一个数学框架来分析所提出的方案的性能,并使用马尔可夫模型来获得lsa内和lsa间切换参数的紧密形式表达式。数值结果表明,与现有的LISP-MN协议相比,该方案在intra-LSA和inter-LSA切换中,每个移动节点的信令开销分别节省38%和21% (K=3)。
