“…However, despite the need to provide seamless handover in VANETs, there are few studies regarding mobility protocols and there are no practical studies on mobility protocols using IEEE Wireless Access in Vehicular Environments (WAVE) communication [67] The random waypoint (RWP) model, in which mobile node movement is considered random, is commonly employed in study of MANETs. Due to the highly dynamic characteristics of VANETs, network partition or merging can occur frequently, which results in the unavailability of existing route or availability of better routes.…”

Abstract-Unmanned Aerial Vehicles (UAVs) have enormous potential in the public and civil domains. These are particularly useful in applications where human lives would otherwise be endangered. Multi-UAV systems can collaboratively complete missions more efficiently and economically as compared to single UAV systems. However, there are many issues to be resolved before effective use of UAVs can be made to provide stable and reliable context-specific networks. Much of the work carried out in the areas of Mobile Ad Hoc Networks (MANETs), and Vehicular Ad Hoc Networks (VANETs) does not address the unique characteristics of the UAV networks. UAV networks may vary from slow dynamic to dynamic; have intermittent links and fluid topology. While it is believed that ad hoc mesh network would be most suitable for UAV networks yet the architecture of multi-UAV networks has been an understudied area. Software Defined Networking (SDN) could facilitate flexible deployment and management of new services and help reduce cost, increase security and availability in networks. Routing demands of UAV networks go beyond the needs of MANETS and VANETS. Protocols are required that would adapt to high mobility, dynamic topology, intermittent links, power constraints and changing link quality. UAVs may fail and the network may get partitioned making delay and disruption tolerance an important design consideration. Limited life of the node and dynamicity of the network leads to the requirement of seamless handovers where researchers are looking at the work done in the areas of MANETs and VANETs, but the jury is still out. As energy supply on UAVs is limited, protocols in various layers should contribute towards greening of the network. This article surveys the work done towards all of these outstanding issues, relating to this new class of networks, so as to spur further research in these areas.Index Terms-Unmanned Aerial Vehicle, UAV, Multi-UAV Networks, ad hoc networks, communication networks, wireless mesh networks, software defined network, routing, seamless handover, energy efficiency I. INTRODUCTION A. The growing importance of UAV networksUnmanned Aerial Vehicles (UAVs) are an emerging The latter ones are proving to be quite useful in civilian applications. As described by Daniel and Wietfeld in [1] they are likely to become invaluable inclusions in the operations of police departments, fire brigades and other homeland security organizations in the near future. Besides, advances in electronics and sensor technology have widened the scope of UAV network applications [2] to include applications as diverse as traffic monitoring, wind estimation and remote sensing [3].In this context it would be relevant to mention that the current FAA guidelines allow a government public safety agency to operate unmanned aircraft weighing 4.4 pounds or less, within the line of sight of the operator; less than 400 feet above the ground; during daylight conditions; within Class G airspace; and outside of 5 statute miles from any airport, heliport, seapl...

“…In the other hand, if geographical addresses are used, an additional identification field may be added to the geographical address such that the message is delivered to only one vehicle. 4G emerging wireless technologies such as LTE and WiMAX have been proposed in [8] to implement V2I. 4G involves technologies that provide faster downlink speeds and packet-switched delivery for VoIP.…”

As vehicles become increasingly intelligent, it is expected that in the near future they will be equipped with radio interfaces. This will enable the formation of vehicular networks, commonly referred to as VANETs, an instance of mobile ad hoc networks with cars as the mobile nodes. As VANETs exhibit several unique features (e.g. high mobility of nodes, geographic extension) traditional security mechanisms are not always applicable. Consequently, a plethora of research contributions have been presented to cope with the intrinsic characteristics of vehicular communication. This paper outlines the communication architecture of VANETs and discusses the security and privacy challenges that need to be overcome to make such networks practically viable. It compares the various cryptographic schemes that were suggested for VANETs and explores some future trends that will shape the research in cryptographic protocols for intelligent transportation systems.

Those works are either application oriented approach [44,45] or policy-enabled approach [46].

In vehicular communication networks, to facilitate the variety of intelligent transportation system (ITS) applications, handover management is considered as the one of the most challenging research issues. The most compatible and interoperable handover management solutions are designed based on IP mobility protocols. However, due to the unique characteristics of vehicles such as high velocity, IP mobility management protocols are still unacceptable for ITS real-time applications that are sensitive to network latencies. Thus, whenever the vehicle roams between two domains, which is most likely to occur in vehicular networks, its reachability status will be broken-down causing high handover latency and inevitable traffic loss. Recently, proxy mobile IPv6 (PMIPv6) has been proposed to support the mobility management without any intervention of the mobile user in the mobility-related signaling. As PMIPv6 will be deployed in the wireless technologies for next generation networks (i.e., LTE/LTE-advanced, WiFi and WiMAX), vehicular ad hoc networks (VANETs) are expected to employ PMIPv6 protocol in vehicle to infrastructure connection as well. In this paper, we introduce a comprehensive review of the state of the art of PMIPv6 handover management in VANET. We present a new taxonomy and classify the existing schemes according to different considerations. Finally, we outline several open issues and handoff management design considerations as a direction for future research.
