“…It has also been shown how SDN can be used to support wireless communication paths with dynamic mobility management capabilities provided by standards compliant nodes. The combination allows enhanced connectivity scenarios; allowing 'always best' connectivity when multiple handover candidates are available and OpenFlow procedures are triggered preemptively in order to avoid traffic disruption [77]. …”

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...

“…The usage of the brokerage service in scenarios with femtocells seems a very interesting future research direction. In addition, if necessary, the main innovations of our proposal can be migrated to an environment combining both SDN/NFV [20][21][22][23]41] and Wireless Networking for Moving Objects (WiNeMO) [5].…”

Abstract-Future wireless networks need to offer orders of magnitude more capacity to address the predicted growth in mobile traffic demand. Operators to enhance the capacity of cellular networks are increasingly using WiFi to offload traffic from their core networks. This paper deals with the efficient and flexible management of a heterogeneous networking environment offering wireless access to multimode terminals. This wireless access is evaluated under disruptive usage scenarios, such as flash crowds, which can mean unwanted severe congestion on a specific operator network whilst the remaining available capacity from other access technologies is not being used. To address these issues, we propose a scalable network assisted distributed solution that is administered by centralized policies, and an embedded reputation system, by which initially selfish operators are encouraged to cooperate under the threat of churn. Our solution after detecting a congested technology, including within its wired backhaul, automatically offloads and balances the flows amongst the access resources from all the existing technologies, following some quality metrics. Our results show that the smart integration of access networks can yield an additional wireless quality for mobile flows up to thirty eight percent beyond that feasible from the best effort standalone operation of each wireless access technology. It is also evidenced that backhaul constraints are conveniently reflected on the way the flow access to wireless media is granted. Finally, we have analyzed the sensitivity of the handover decision algorithm running in each terminal agent to consecutive flash crowds, as well as its centralized feature that controls the connection quality offered by a heterogeneous access infrastructure owned by distinct operators.

“…However, the details about the integration of OpenFlow and IEEE 802.21 are not clear, with no benefits being highlighted. In previous work [9], the authors progressed this issue with an integration of OpenFlow with IEEE 802.21, by describing a framework that couples both mechanisms for the dynamic optimized support of OpenFlow path establishment and wireless connectivity establishment. However, this uses a decoupled approach, forcing entities to support both protocols in parallel.…”

The evergrowing availability of access technologies, on-line services and connected devices has been motivating the development of novel networking solutions, fostering new deployments of cloud computing, Network Function Virtualization and even mobile accesses. One of the core aspects supporting these innovative solutions is the Software Defined Networking (SDN) concept, which brings added configuration and management capabilities to the network fabric, aiding the support and introduction of new technologies and protocols. However, the base operations of SDN do not consider link conditions when employing their controlling mechanisms and mostly target fixed core links. These link conditions are important to optimizations involving wireless access links, which are paramount in today's plethora of wireless and mobile accesses. This paper enhances SDN mechanisms with Media Independent Management capabilities, deployable in both wired and wireless environments, optimizing link connectivity establishment and offering new perspectives to network developers for building new capabilities in the networks. The resulting framework was implemented over open-source software in a physical testbed, with results showing the benefits that this solution brings in terms of path optimization, featuring different monitoring schemes and allowing energy efficient scenarios.
