Mobility Management Approach for Future Aviation Ipv6 Networks

Abstract

As the use of IPv6 Network and methods of aircraft air to ground connectivity will continue to increase, seamless mobility becomes more desirable and important. The current IETF Mobile IP standard relies on additional network entities for mobility management, can have poor performance, and has seen little deployment in real networks. We present an approach for the mobility solution with a true end-to-end architecture using the mixed approach. The future aviation IP mobile networks must cope up with many challenges and to cope these challenges, different standards need to be considered. Most recently Mobile IPv6 Networks has still does not present suitable architecture or mechanism that must function properly in the performance specific aviation environment. It has many challenges. The objective of this paper is to identify and discuss the challenges to the future IPv6 air to ground mobile networks and to discuss some workable solutions to these challenges. Finally, on the framework of aviation safety service communication discussion a simple but flexible network architecture is proposed. Using this flexible network architecture, we will show how the existing COTS equipment’s can be extended allowing both legacy and new applications. Performance comparison shows that mobility approach provides better mobility support with the Mobile IPv6 in terms of session continuity, packet loss, and handoff delay for upper layer protocols. We also explore how the performance base of IP protocol may not satisfactory in aviation mobile environments, due to lack of handover support and higher layer mobility management mechanisms. In this paper, we outline the most important current methods of handling mobility in IP networks that are expected to play an important role in the future aviation air to ground communication.
