This work presents a comprehensive and structured taxonomy of available techniques for managing the handover process in mobility architectures. Representative works from the existing literature have been divided into appropriate categories, based on their ability to support horizontal handovers, vertical handovers and multihoming. We describe approaches designed to work on the current Internet (i.e. IPv4-based networks), as well as those that have been devised for the "future" Internet (e.g. IPv6-based networks and extensions). Quantitative measures and qualitative indicators are also presented and used to evaluate and compare the examined approaches. This critical review provides some valuable guidelines and suggestions for designing and developing mobility architectures, including some practical expedients (e.g. those required in the current Internet environment), aimed to cope with the presence of NAT/firewalls and to provide support to legacy systems and several communication protocols working at the application layer. application level. While throughput remains a major goal of system design, the main concern of mobility architectures is how to best manage situations where a MN changes network. This event is currently referred to as handover (or handoff ).By default, current operating systems installed on smartphones adopt the following strategy for data transmission: one Network Interface Card (NIC) at a time is configured and employed to send data. If a WiFi network is available, the terminal switches to WiFi; otherwise a cellular network is utilized, if the latter is available too. During the handover, communications are interrupted. While the widespread use of current smartphones confirms that in general such a simple approach may be a viable solution, in some cases this strategy has some severe limitations. Just as an example (which is actually a true story), let us consider the case of an employee working in an institution/company composed of several buildings, all covered by a WiFi network (e.g. a researcher in a university campus). Suppose that the researcher is a commuter and, just before leaving for going home, he/she receives an important Voice over IP (VoIP) phone call. Since he needs to leave to take the last train home, he decides to answer the call using his/her mobile phone; today, there are plenty of smartphone apps that offer very efficient VoIP services. At that moment, the device is connected through WiFi, but when he gets out of the building, the WiFi signal is lost and the smartphone automatically switches to 4G without any handover management at the application level, thus experiencing a first communication interruption. While moving, he passes through other buildings (hence, within their WiFi coverage); as a consequence, the smartphone switches back to WiFi (i.e. a second communication interruption occurs), and then back to 4G (i.e. yet another communication interruption) and so on. One might suggest that the employee should turn off the WiFi NIC before leaving, thus using the cellular...

“…As it is currently defined, PMIPv6 does not provide flow mobility support in any of the previous flavors, so we described a set of extensions in [2], mainly affecting the mobility signaling exchanged between LMA and MAG and the data structures maintained by each element. We summarize these extensions in the following section.…”

Current trends on mobile traffic show an exponential grow of the traffic consumed by users from smartphones and other portable devices. The explosion of traffic in cellular networks has forced operators to start deploying solutions to alleviate the congestion on their capacity-limited and expensive radio access networks. One of the solutions being discussed is the so called 3G offload that enables the terminals to use other technologies such as WiFi to offload some of the traffic. IP flow mobility is one mechanism providing 3G offload, by enabling selected flows to be moved among network interfaces. Although this is a very promising technology, it is not clear yet how it will affect the protocols currently in use to provide IP mobility in cellular networks, e.g., Proxy Mobile IPv6. The use of 3G offloading does not only benefits the operators, but also the final user, as it might extend the battery lifetime of its terminal. In this paper we first describe some network-based IP flow mobility extensions, highlighting important design choices. Secondly, we focus on providing experimental measurements showing how the use of this technology can result in an extended battery life for the case of 3G and WiFi enabled terminals.

“…On the other hand, there also exists a considerable amount of previous work in the area of IP mobility in heterogeneous environments, even considering flow mobility [39] and offloading techniques [40]. However, most of the IP mobility works proposed so far [41] do not deal with the specifics of the vehicular scenario, and those that tackle it do not attempt to opportunistically benefit from multi-hop WLAN connectivity, enhancing in this way both users' and operators' interests, as SIL-VIO does.…”

Most of the cellular network operators are nowadays striving to solve the problem caused by the increasing demand of mobile data users. In the near future, vehicles will be equipped not only with cellular connectivity, but also with dedicated short-range wireless devices, used to connect via single or multiple hops to fixed road side units attached to the infrastructure network to gain Internet access. Taking this hybrid-connectivity scenario, we propose Seamless Internet 3G and Opportunistic WLAN Vehicular Internet Connectivity (SILVIO), a solution for providing Internet connectivity in multi-hop vehicular ad hoc networks. Vehicles use the cellular network to assure always-on connectivity, while they opportunistically select to offload some non-critical flows to the multi-hop wireless local area network (WLAN). The advantages of this approach are twofold: the users can benefit from a higher bandwidth, while the operators can alleviate their overloaded cellular networks. SILVIO makes use of existing standard mobility mechanisms integrated, enhanced and extended to provide a seamless connectivity experience without introducing much complexity nor signalling overhead. One of the main contributions of this article is the proposal and analysis of different handover strategies between 3G and multi-hop WLAN networks for the vehicular scenario. A trace-driven simulator was developed to evaluate the performance improvements provided by SILVIO. Real traffic traces from the city of Madrid were used to feed the simulator which considers large vehicles as obstacles, as well. The obtained results show that using SILVIO the cellular network can be offloaded by a factor up to 80%.
