Abstract
Vehicular Ad-hoc networks (VANETs) are a kind of wireless Networks that are specifically designed to provide road safety, infotainment, commercial and traffic monitoring services. In the VANET, user has to access real-time traffic monitoring updates, road hazard notification, audio and video streaming to enhance the travel experience. In VANET, moving nodes behave like as vehicles, which move at high speed and because of this network topology change rapidly. Due to this a node becomes non-reachable from its current position of attachment if it moves out of the range, so we need to do management of mobile nodes to ensures that a node gets the continuous services while it is roaming within its current point of attachment or attached to another network. To achieve seamless mobility, mobility managements are considered. The mobile ipv6 (MIPV6) is proposed and standardized by IETF [1]. It is introduced to improve the host-based mobility management. However, it faces the different problems when mobile node moves between different network infrastructures. So to overcome this issue proxy mobile ipv6 (PMIPV6) is introduced. PMIPV6 is a network-based localized mobility protocol, which means a mobile node is not required to perform any mobility functionality in its stack of protocols [2]. pmipv6 perform handover for mobile nodes but it can only manage mobile nodes reachability with in a local domain but if the mobile node move beyond the border then its pmipv6 inability to cover nodes or local network beyond its coverage area. So in this situation mobility support will be broken. We are developing VANEMO (vehicular network mobility) scenario where vehicles will behave like as mobile node. In this Research paper, author proposing a development model of VANEMO for NEMOSMART to provide continuous support to the mobile nodes using Multi-hop routing among nodes to solve single hop issue in NEMO'S local domain. In the MULTIHOPING scenario, we are using OLSR routing protocol to connect various nodes outside the local domain of pmipv6 and create Vehicular Ad-hoc network.
