“…Nevertheless, we note that the method for measuring the TBIT metric does not consider the time consumed by erroneous transmissions (e.g., collisions), and due to this reason the measured number and duration of the idle time periods are not correct. Furthermore, in [38] the performance evaluation (i) does not consider the presence of heterogeneous voice codecs, (ii) does not consider the case in which STAs use different PHY rates, (iii) does not show any numerical result for the case in which background traffic is present and (iv) does not consider objective quality metrics as E-model [21]. All these conditions are commonly encountered in the vast majority of real WLAN scenarios, and could negatively affect the performance of a distributed CAC scheme.…”

Nowadays many manufacturers are building mobile devices with multiple interfaces. Thus, users have access to different types of wireless access networks, which often, as for WLAN and cellular systems, coexists independently. The challenge is to make such multiple access networks to cooperate to have ubiquitous access and enhanced user quality of service. In this paper we present a scheme to allow inter-technology mobility by the introduction of an overlay network, which works on top of current (and future) networks. The proposed architecture controls all the aspect related to the mobility management: mobile node localization, handover decision and execution. The approach is distributed: it is the mobile node that decides which network to use, based on the offered service quality and the cost of the communication of the available networks, and triggers the handover execution directly to the corresponding host, using optimized SIP-based procedures. The overlay network copes with the mobile node localization. We implemented our solution in the laboratory to prove its validity and to test performance using real equipment. We also simulated the scheme using ns-3 to extend the evaluation to large scale deployments. In both test environments, our solution demonstrates high accurateness in selecting the network with the best quality as well as in supporting seamless vertical handover.

Nowadays, mobile users wish to use their multiinterface mobile devices to access the Internet through network points of attachment (PoA) based on heterogeneous wireless technologies. They also wish to seamlessly change the PoAs during their ongoing sessions to improve service quality and/or reduce monetary cost. If appropriately handled, multihomed mobile nodes offer a potential solution to this issue. In this sense, the management of multihomed mobile nodes in heterogeneous environment is a key research topic. In this paper, we present an improvement of SIP mobility (pre-call plus mid-call mobility) to support seamless mobility of multihomed mobile nodes in heterogeneous wireless networks. Pre-call mobility is extended to associate user identifier (i.e. SIP URI) and interface identifiers (i.e. IP addresses). The multiple addresses of a mobile device are weighted by the user to create a priority list in the SIP server so as to guarantee resilient reachability of mobile nodes and to avoid unnecessary signaling through wireless links, thus saving radio resources. Then, three variations of mid-call mobility, called hard, hybrid and soft procedures, are also proposed. Their main aim is to minimize, or even avoid, packet losses during interface switching at the mobile node. The proposed solutions have been implemented in a wireless heterogeneous testbed composed of 802.11 WLAN plus 3.5 cellular network, which are fully controlled and configurable. The testbed has been used to study the performance and the robustness of the three proposed midcall mobility procedures.

The latest advances in wireless data access technologies and increased popularity of mobile computing have enabled the development of the future mobile Internet. The various wireless technologies and standards already developed or under development support the existence of a highly heterogeneous wireless communication environment in which mobile users access the network from diverse devices and exchange data of various types. In the context of such a heterogeneous wireless and mobile environment, maintaining certain level of Quality of Service required by some applications and consequently providing high user Quality of Experience is very challenging. This chapter analyzes the state of the art in quality-oriented mobility management in heterogeneous wireless environments in the context of mobile multimedia applications. Most important wireless access technologies and multimedia support systems and protocols for wireless delivery are presented, while requirements for quality-oriented mobility management are identified. Handover management is discussed as the component of the mobility management system with the greatest impact on the quality as measured by the user. Finally a novel multimedia mobility management framework is presented which aims at maintaining high user perceived quality while efficiently exploiting all the communication resources available in a heterogeneous wireless environment.
