“…This is related to the fact that the handover control signals have sufficient time to reach to the SDN controller to take action for handover management at low vehicle speed. Particularly, the proposed system of SDN-FC produces lower HL compared to the traditional 1577 SDN based system [19], [20]. The reason is twofold: first, the processing capabilities of FC at the edge network, which provides the best measurement parameters to select the new BS.…”

“…In summary, the traditional SDN based handover in previous mentioned studies [20]- [25] shows notable challenges due to handover operation with the centralized SDN controller. These studies generate higher handover latency and higher packet losses as the handover controller signals take long delay time from vehicle at edge network to the centralized SDN controller at the core network.…”

<p>Vehicular ad-hoc networks (VANET) suffer from dynamic network environment and topological instability that caused by high mobility feature and varying vehicles density. Emerging 5G mobile technologies offer new opportunities to design improved VANET architecture for future intelligent transportation system. However, current software defined networking (SDN) based handover schemes face poor handover performance in VANET environment with notable issues in connection establishment and ongoing communication sessions. These poor connectivity and inflexibility challenges appear at high vehicles speed and high data rate services. Therefore, this paper proposes a flexible handover solution for VANET networks by integrating SDN and fog computing (FC) technologies. The SDN provides global knowledge, programmability and intelligence functions for simplified and efficient network operation and management. FC, on the other hand, alleviates the core network pressure by providing real time computation and transmission functionalities at edge network to maintain the demands of delay sensitive applications. The proposed solution overcomes frequent handover challenges and reduces the processing overhead at core network. Moreover, the simulation evaluation shows significant handover performance improvement of the proposed solution compared to current SDN based schemes, especially in terms of handover latency and packet loss ratio under various simulation environments.</p>

A Vehicular Mobility Management Scheme for a Shared-Prefix Model Over IEEE WAVE IPv6 Networks

The IETF IPWAVE Working Group is developing an IPv6-based solution to establish connectivity for V2V and V2I communication. It proposes a vehicular mobility management scheme based on PMIPv6. In this scheme, a shared-prefix model is proposed for its vehicular link model. The shared-prefix model is to share a common prefix among several RSUs. When using it, a vehicle in the same prefix domain does not need to change its IPv6 address even if its serving RSU is changed. So its CNs do not notice the movement of the vehicle. This concept is very similar with PMIPv6, because PMIPv6 also hides the vehicle's movement to its CNs if PMIPv6 does not use the route optimization. However, current IPWAVE draft of vehicular mobility management has several problems. Firstly, it requires a vehicular neighbor discovery, which is not compatible with standard IPv6 NDP. Secondly, PMIPv6 assumes that it acquires a MN-ID and a profile of a mobile node during the network attachment, but there is no authentication in IEEE WAVE networks. So, such information cannot be acquired in IEEE WAVE networks. We propose a vehicular mobility management scheme for a shared-prefix model over IEEE WAVE IPv6 networks. The proposed scheme introduces VMM-NDP module. It handles the path changes due to the serving RSU changes within a shared prefix domain. It also hides the IPv6 address change to CNs by maintaining the previous IPv6 address when the vehicle's current IPv6 address is changed due to the movement of the vehicle into new shared prefix domain. In this scheme, a vehicle can know its movement. So, there is no need to acquire a MN-ID. And also, since this scheme uses a shared-prefix model, there is no need to obtain a profile.

INTRODUCTION The IETF IP Wireless Access in Vehicular Environments (IPWAVE) Working Group (WG) is developing an IPv6based solution to establish direct and secure connectivity for Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication [1]. It proposes a new vehicular link model for its IPWAVE architecture called a shared-prefix model in which multiple Road Side Units (RSUs) in the same subnet share a common prefix. By using the shared-prefix model, when a vehicle passes through another RSU in the same subnet, it can use its current IPv6 address in the wireless coverage of the RSU. So, its Correspondent Nodes (CNs) do not notice the movement of the vehicle. In addition, since multiple RSUs share one prefix, this model can save prefixes. Therefore, it is quite attractive to apply the shared-prefix model to IEEE Wireless Access in Vehicular Environment (WAVE) networks. The IPWAVE WG has proposed Vehicular Neighbor Discovery (VND) [2]. VND defines the shared-prefix model and takes into account Neighbor Discovery (ND) optimization that considers the wireless link properties such as asymmetric reachability [3] and und...

As redes veiculares ad hoc (VANETs) possibilitam que passageiros de veículos inteligentes usufruam de aplicações multimídias, como chamadas VoIP e streaming de vídeo. Contudo, as VANETS são redes altamente dinâmicas, com veículos se movendo frequentemente entre as células de cobertura dos pontos de acesso, o que pode causar interrupções no fornecimento das aplicações. Dessa forma, procedimentos efetivos de handoff para manter a continuidade do fornecimento de conteúdo enquanto os veículos se locomovem se tornam imperativos. Este artigo apresenta um mecanismo de handoff definido por software e com suporte à multihoming para garantir o handoff transparente em um cenário veicular heterogêneo (Redes IEEE 802.11p e LTE), assegurando os níveis de QoS/QoE exigidos pela aplicação de tempo real. Os resultados de simulação mostram a eficácia do esquema proposto em comparação a técnica baseada em RSSI.
