Now-a-days, mobile nodes (MNs) are being used with multiple network interfaces so that an MN may have a ubiquitous communication. Mobile Internet Protocol version 6 (MIPv6) allows an MN to maintain the ubiquitous connectivity regardless of any type of network interface while it changes the point of attachment in heterogeneous network environment. In this paper, we have studied a vertical handover with the help of MIPL based test-bed to analyze handoff latency and packet loss. The vertical handover has been considered between Ethernet and Wi-Fi network access. We have analyzed the performance during MN's handover across the networks. The results show that such type of setting could be used in various practical-oriented consumer applications that need to have mobility feature of nodes.
Mobile nodes with dual interfaces are not very common and not many studies have been done in this area. In this work, we have done a comprehensive study of dual interfaces on a test-bed to find out the effectiveness of dual interfaces and compared the results with single interface. We have implemented an MIPL based test-bed to study the QoS parameters, which affect mobile nodes, and are considered to be of paramount importance in real time application running on MIPv6 mobile nodes. The hand-off latency, packet loss, data throughput and jitters are the parameters we have considered in this research. Finally, we show a comparison of performance between dual interfaces and single interface on a mobile node.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
