Measurement-Based Comparison of IPv4/IPv6 Mobility Protocols on a WLAN Scenario
نویسندگان
چکیده
This paper focuses on a measurement-based comparison of the handover for different mobility protocols: Mobile IPv4, Mobile IPv6 and Fast Handovers for Mobile IPv6. The paper studies the handover using active and passive measurements computing the handover latency, packet losses and the provided QoS level in a real testbed. Our experimental results show that there are severe QoS fluctuations before the handover for Mobile IPv4 and Mobile IPv6, moreover Mobile IPv6 has unacceptable handover latency for real time traffic. Our implementation of Fast Handovers for Mobile IPv6 behaves as expected, reducing the Mobile IPv6 handover latency, delaying packets instead of losing them and maintaining the level of provided QoS before and after the handover.

A Service Management Architecture for NEMO in IPv4 and IPv6 Networks
The current design of Mobile IPv4 and Mobile IPv6 protocols doesn’t provide the compatibility between networks of different versions. A Network Mobility(NEMO) protocol also provides the limited mobility in IPv6 networks. However, we can easily expect that the current IPv4 network will coexist with IPv6 network in the near future internet environment. So, in this paper, we propose the architectu...

متن کاملOn the Security of the Mobile IP Protocol Family
The Internet Engineering Task Force (IETF) has worked on network layer mobility for more than 10 years and a number of RFCs are available by now. Although the IETF mobility protocols are not present in the Internet infrastructure as of today, deployment seems to be imminent since a number of organizations, including 3GPP, 3GPP2 and Wimax, have realized the need to incorporate these protocols in...
متن کاملToward Ipv4 to Ipv6 Migration within a Campus Network
The evolution of the Internet has effectively exhausted all unique addresses offered by the current IPv4 protocol. Hence, IPv6 has been developed in response to the predicted long-term demand for addresses by Internet users. This new IP version has a 128-bit address length, which is four times that of IPv4. As the two protocols have different formats and behaviors, efforts are needed to ensure ...
متن کاملRFC 4977 Problem Statement : Dual Stack Mobility August 2007
This document discusses the issues associated with mobility management for dual stack mobile nodes. Currently, two mobility management protocols are defined for IPv4 and IPv6. Deploying both in a dual stack mobile node introduces a number of problems. Deployment and operational issues motivate the use of a single mobility management protocol. This document discusses such motivations. The docume...
