Load balancing scheme and implementation in multihoming mobile router

Abstract

In this paper, we consider a multihoming mobile router to be connected via dual interfaces such as WLAN (Wireless LAN) and WiBro (Mobile WiMAX). In order to provide redundancy and fault tolerance, we propose load balancing scheme using policy routing in a mobile router. This scheme can improve network reliability and guarantee the continuous connectivity with desirable Quality of Service (QoS). To efficiently support multihoming and network mobility in mobile router, we provide the implementation method of our proposed scheme using netfilters tool of Linux and show the performance results in our experimental environment.
