Mobile Ip Handover: a Comparative Survey of Seamless Handover Mechanisms
نویسندگان
چکیده
A seamless handover scheme with low latency and low packet loss is an important issue to maintain end-to-end TCP performance of mobile users. Several solutions have been proposed as extensions of Mobile IPv6 to improve the handover performance of mobility, each solution has its own advantages and disadvantages, and therefore, an standardized handover mechanism is not accepted yet. In this paper, we propose a comparative survey of typical handover mechanisms with an aim to figure out the way of optimization of the handover process. The handover mechanisms we choose to analyze are Mobile IPv6, Hierarchical Mobile IPv6 and Fast handover protocol. Before the survey, we examine the impact of latency and packet loss as result of the handover process on TCP performance. We also present the simulation result of these solutions together with the evaluation model we use in the testbed.

On the Layer based Seamless Handover Schemes for Mobile Data Network
This paper presents seamless handover schemes survey based on layer approach. Efficient handover scheme is very important in order to minimize the handover latency in mobile network. Latency is mainly affected when new IP address has to be obtained in layer 3 and layer 4 handover mechanisms because this is processed by software. Therefore, we have to focus on the exact mechanism to obtain new I...

متن کاملHandover latency comparison of SIGMA, FMIPv6, HMIPv6, and FHMIPv6
In our earlier study, we proposed SIGMA, a Seamless IP diversity based Generalized Mobility Architecture. SIGMA utilizes IP diversity to achieve a seamless handover of a mobile host, and is designed to solve many of the drawbacks of Mobile IP. In this paper, we compare the handover latency of SIGMA and recent MIPv6 enhancements, namely, FMIPv6, HMIPv6, and FHMIPv6. Various parameters are consid...

We propose and estimate a novel transport layer mobility management scheme: Seamless IP diversity based Generalized Mobility Architecture (SIGMA). SIGMA provides seamless handover for mobile hosts and is based on Stream Control Transmission Protocol (SCTP), which is a new dependable transport protocol to transport SS7 signaling messages over IP network. We also show that our handover scheme can...
