The scheme of handover performance improvement in WiBro

Abstract

Demands for a mobile communication and a high quality service such as video streaming or VoIP have been increasing in recent years. The Wireless Broadband Internet (WIBRO)system, which is specified by ETRI (Electronics and Telecommunications Research Institute) and other companies in Korea as well as IEEE 802.16e standard. The feature of this system is that the backbone networks are potentially deployed by IPv6 based technologies due to the All-IP trend. Therefore, it is important to support efficient mobility management protocol on IP layer as well as data link layer based on WiBro system. In this paper, we propose the scheme that different process according to the traffic characteristic. The performance analysis and the numerical results presented in this paper show that our proposal has superior performance. © 2009 Springer Berlin Heidelberg.
