“…The CN for this purpose, receives handover indication through the Handover Start Notification message, and later resumes the normal TCP operation when it receives the Handover Finish Notification message. Likewise, in [125], a cross-layer based interaction between MIPv6 and TCP is proposed, in which the TCP parameters such as RTO, cwnd, ssthresh, RTT etc. are re-adjusted based on the handover initiation and termination indications received from MIPv6.…”

The emerging mobility management schemes for the fifth generation (5G) of mobile networks mostly follow the network-based protocol principles, which do not involve the mobile node (MN) in their operation. Such solutions have not been able to meet the ultra-low handover latency requirement in complex mobility scenarios in 5G. These objectives can be potentially achieved through increased involvement of MN in the handover operation, which can now be conveniently effectuated through virtualization technologies. In this regard, the classical host-based Fast Handovers for Mobile IPv6 (FMIPv6) protocol has the potential to offer several benefits due to its distinctive features, such as link-layer assistance for handover preparation, in-advance new care-of address formulation, and buffering services. Several enhancements to the FMIPv6 protocol have also been proposed, which improve its handover performance. Many of these enhancements focus on the baseline FMIPv6 specification, while others aim to enhance its operation by adding support features, such as mobile multicast, vertical handovers, quality of service assurance, as well as security support. Moreover, several enhancements to the access-technology-specific solutions for FMIPv6 have also been proposed. This paper aims to provide a systematic review of FMIPv6 enhancements in order to gain insight into its advantages as well as its shortcomings. Based on the review, this paper also discusses the evolution prospects of FMIPv6 toward 5G. Finally, some of its potential limitations along with possible research directions in the context of 5G are also indicated.

“…There are several methods to prevent the lion attacks. Le et al [18] introduced a cross-layer design by using a mobility detection element in the network layer that informs the transport layer to optimize TCP operations. TCP-feedback has been proposed in [19] to help the TCP sender distinguish between losses due to routes failure and network congestion.…”

Defense against Lion Attack in Cognitive Radio Systems using the Markov Decision Process Approach

Cognitive radio (CR) technology is a solution to solve the lack of spectrum by allowing the secondary user to use licensed bands. There are several potential security challenges for cognitive radio like jamming, primary user emulation (PUE) and lion attack. The lion attack is a multilayer attack that has effects on two layers. It uses PUE or jamming attack in physical layer to disrupt transmission control protocol (TCP) in transport layer. Since transport layer is unaware of physical layer situation, when it occurs to an unacknowledged packet, there is no way to distinguish between congestion and disconnection in the physical layer. So the window size of TCP would be decreased because of a wrong decision caused by unawareness. To mitigate the lion attack the cross layer design is usually used to freeze its window size during frequency handoff. The main issue in this solution is finding the best strategy for freezing. In this paper, we propose a dynamic method for freezing and performing frequency handoff to counter lion attack. Also a learning model based on Markov decision process (MDP) is applied. By using the proposed method, the secondary user can choose an optimal strategy in both physical and transport layers to reduce the effect of lion attack.

“…NB: there are also cross layer approaches, which are not shown in Table 3. These approaches require certain modifications either on the TCP sender and/or the receiver side [28,29,30] Inter-AN Handover Intra-AN Handover BS-buffering and AR-buffering methods are only suitable for intra-access network handovers, since they require signaling between access routers or base stations and such kind of collaboration and trust relationship may not be possible between different access network service providers. In addition, these approaches require major modifications on the existing access network infrastructure (i.e., software update and configuration of all BSs and ARs).…”

The aviation community is currently working on the standardization of data communication systems for the future air traffic management. In this context, International Civil Aviation Organization (ICAO) has initiated a work on standardization of an IPv6-based aeronautical telecommunications network and on future radio access technologies, respectively. In this paper, we integrate L-Band Digital Aeronautical Communications System Option 1 (L-DACS 1), which is one candidate for future radio access technologies, with realistic IPv6-based network layer functionality and analyze the effect of handover delay to the TCP performance. Realistic Frame Error Rate (FER) values obtained from an L-DACS 1 physical layer simulator, which uses a realistic aeronautical channel model, are used in the simulation experiments. In the first stage, we decreased layer 3 handover latency by removing the Duplicate Address Detection (DAD) procedure for address configuration. In the second stage, we introduced a Home Agent (HA)-buffering method, which is used to buffer the traffic (destined to the mobile node) during handover. Transmission completion time is the primary performance metric in our analysis. With the HA-buffering method, the transmission completion time is reduced by at least 10% for the transmission of 110 kB of information over a wireless link with 31.5 kbit s −1 data rate.
