Multi-interfaced mobile router scheme and enhanced path selection algorithm

Network mobility (NEMO) aims providing seamless Internet connectivity for the network which is moving around with vehicles. Multiple care of addresses (MCoA) registration was also proposed as an extension. This paper studies the seamless Internet connectivity of mobile router (MR) which is equipped with WLAN, CDMA and GPRS interfaces simultaneously. Concretely, a smooth inter-interfaces hand-off algorithm is proposed and experimented on our platform successfully, traffics are transferred smoothly between different interfaces without packet loss. We also propose a path selection algorithm based on the measured parameters for better performance. Numerical analysis is also proposed and paths are compared in term of packet delivery delay.
