“…The simulation results presented in [1] show that packets sent during the handover with LLH or FMIPv4 experience the delay not longer then 100 ms. Although the simulation scenarios were different, we can estimate that SMIPv4 handover delay is shorter compared with the LLH and FMIPv4 protocols.…”

Handover performance in wireless networks is important, especially nowadays, when multimedia services are becoming increasingly available over the wireless devices. However, users expect uncompromised mobility when using the service. Thus, the support of multimedia services is not possible if handover is inefficient. At the same time it is clear that a strict separation between IP Layer and the Link Layer results in built-in sources of delay. The paper discusses the IEEE 802.11 and Mobile IPv4 handover performance in practical scenarios. We introduce a new simultaneous handover scheme with IEEE 802.21 triggers. In order to verify the handover performance, simulation experiments have been conducted, whose results are also presented and discussed.

Abstract-One of the most important challenges in MobileIPv6 is to provide the service for a mobile node to maintain its connectivity to the Internet when it moves from one domain to another, which is referred to as handover. Here we deal with the fast handover problem, which is to provide rapid handover service for the delay-sensitive and real-time applications. In this paper, we propose an enhanced fast handover scheme for Mobile IPv6. In our scheme, each AR (Access Router) maintains a CoA (Care of Address) table and generates the new CoA for the MN that will move to its domain. At the same time, the binding updates to home agent and correspondent node are to be performed from the time point when the new CoA for MN is known by PAR (Previous AR). Also the localized authentication procedure cooperated with the proposed scheme is provided. For the comparison with the existing fast handover scheme, detailed performance evaluation is performed. From the evaluation results, we can see that the proposed enhanced fast handover scheme can achieve low handover latency and low packet delay.Index Terms-Mobility, mobile IPv6, fast handover scheme, enhanced fast handover scheme, performance analysis.

SUMMARYMobile IPv6 (MIPv6), which is a protocol being standardized by Internet Engineering Task Force for global IP mobility support, is expected to have a key role for future All-IP wireless networks. As the demands for delay sensitive multimedia applications increase, the handover latency and packet losses of MIPv6 become inadequate for these applications. Fast Handovers for Mobile IPv6 (FMIPv6) has been proposed to tackle the problem. However, FMIPv6 cannot work solely since it needs access router information for its fast handover operation. In this paper, we propose Access Router Information Protocol (ARIP), which performs a candidate access router discovery and a radio access network discovery in one protocol suite, to provide an efficient handover framework for MIPv6 and FMIPv6. ARIP is designed to cope with heterogeneous networks as well as homogeneous networks and to be closely coupled with FMIPv6 to provide the efficient handover performance. The performance evaluation of MIPv6, FMIPv6, and FMIPv6 with ARIP is performed in an actual network environment. The performance results show that FMIPv6 with ARIP can significantly improve the handover performance compared to the conventional handover approaches.
