Experimentation and analysis on multiple interfaces mobile router scheme between overlay heterogeneous access networks

Abstract

Network mobility (NEMO) aims managing seamless connectivity for a group of mobile terminals as a whole mobile network. Multiple care of addresses (MCoA) registration scheme was also proposed to address seamless Internet connectivity issue. In this paper we first analyze the upload and download packet loss of mobile router (MR) in NEMO basic support protocol. Then the seamless Internet connectivity of MR which is equipped with WLAN, CDMA and GPRS interfaces is studied and experimented on our platform successfully. Finally, we analyze and compare the performance of packet loss ratio between uni-interfaced and multiple-interfaced MR, and results indicate that multiple interfaced MR can increase the performance of MR obviously when it moves across heterogeneous overlay access networks.
