An Access Router based NEMO Route Optimization Scheme in Aeronautical Passenger Communications Environment

Abstract

IETF has developed the NEtwork MObility Basic Support (NEMO BS) protocol to handle mobility of an entire mobile network and it is considered as a basic solution of aeronautical communication. If this NEMO BS used in Aeronautical Passenger Communications (APC) environment, the basic protocol and the existing route optimization (RO) schemes of it may face some problems such as high end-to-end delay, high signaling overhead or high load of the home agent. In this paper, a brief analysis of NEMO RO in APC is given and a scheme named APCRO is presented to optimize the route of NEMO especially for APC. The key points of our mechanism include: 1) establish an Access Router (AR) to correspondent node (CN) RO scheme to optimize the path on the ground network and 2) update the user's location by the home agent of the mobile router. The evaluation and the comparison with other mechanism illustrate the end-to-end delay of the proposed scheme is as low as possible, in addition, the signaling overhead on the air-to-ground wireless channel in APCRO is the smallest among schemes which have the similar end-to-end delay. So APCRO is feasible and suitable for APC environment.
