“…The most relevant effort of these works is the development of IEEE802.21 [1] standard which is evaluated in [2] and is described how it can be used to provide seamless mobility. Regarding QoS provisioning in vertical mobility, [3] proposes an enhanced MIH framework and simulation results are presented in a heterogeneous environment with WiMAX and Wi-Fi networks. For a broader handover support in Wi-Fi, WiMAX and UMTS networks, [4] describes and evaluates a detailed seamless handover procedure using the IEEE802.21 standard and the NS-2 tool.…”

The growth of available broadband access technologies has brought an enormous challenge for operators wanting to ensure seamless mobility to its customers in heterogeneous environments. In this paper we present an enhanced Mobility Management entity focused on a real heterogeneous environments and based on IEEE802.21 standard. This entity is capable to perform terminal and handover management regardless the access technology used. This entity was deployed in a real heterogeneous environment with Wi-Fi, WiMAX and HSPA using an Android smartphone. In order to provide Layer 3 mobility support it was integrated with a modified version of MIPv6. The results show not only the impact of a centralized entity to manage vertical handovers, but also the performance of IEEE802.21 protocol in a real scenario with a real implementation.

“…The evaluation of the performance of a vertical handoff scheme between 802.11 and 802.16 wireless access networks with respect to signaling cost, handoff delay, and QoS support can be found in [5]. Reference [6] evaluates a proposed cross-layer mechanism for making intelligent handover decisions in FMIPv6 in terms of handover latency, packet loss and handover signaling overhead, and [7] evaluates a new enhanced Media Independent Handover Framework (eMIHF) that allows for efficient provisioning and activation of QoS resources in the target radio access technology during the handover preparation phase.…”

The new IEEE 802.21 standard specifies link layer intelligence and other related network information to upper layers in order to optimize handovers between networks of different types, such as WiMAX, Wi-Fi, and 3GPP. This paper makes a short description of 802.21 standard, how it is implemented in ns-2, and the signaling used in a handover between WiMAX and Wi-Fi. The paper also proposes a novel and very simple approach to determine the expected number of handovers in an ns-2 simulation and also evaluates the reliability and scalability of ns-2 when simulating 802.21 scenarios with multiple nodes.

“…Nevertheless, results are yet to be presented to evaluate and validate their approach. On the other hand, although very simple, remarkable performance studies of seamless mobility scenarios were presented in [22] and [23], for testbed and simulation environments, respectively. However, all these approaches deal with unicast services, and also do not have support for mobility of both sources and listeners.…”

Upon receiving the message, the MTA forwards it to the MTA cor- [16] responding to the new AR. This one, in turn, after authorizing the new mobile terminal in its domain, informs the MSDA about its interest in receiving the stream from the desired group.…”

Mobility of sources and listeners: real-time support of multicast services

In today's Internet there is an increasing demand for group-based multimedia sessions, such as video/audio conferencing, IPTV, push media. Moreover, there is an increasing trend for mobile communications, with large network dynamic events, which require fast resilience to keep, as much as possible, sessions alive over time. In this sense, the bandwidth-constrained data transport scheme of IP multicast allows traffic optimization throughout the network. However, current IP multicast support over mobile communications is not efficient, mainly due to the IP addressing scheme and mobility. If multicast sources mobility is taken into account, then the performance of IP multicast is significantly degraded, due to the requirement for constantly changing the overall multicast tree.In this paper we propose a new solution for agent-based multicast in both sources and listeners mobile environments, called MUlticast TEleport (MUTE). MUTE considers the existence of anchor points in the network that provide proxy features, assuming the view of multicast data source inside the network, and establishing independence between listeners and sources movements. Moreover, we propose MUTE extension to efficiently support time-sensitive sessions, which consists in integrating IEEE 802.21 and QoSaware abstracted transport approach, to allow media independent transport with fast resilience support. The evaluation of MUTE was carried out in NS-2, and the results show that it is able to provide both multicast sources and listeners mobility with decreased disruption time and increased network performance in heterogeneous systems.Keywords IP Multicast · Mobility of source and listeners · Agent-based control · Media independent handovers · Abstract transport trees 1 Introduction
