    Configuration and Planning of the Remote TowerModules in a Remote Tower Center2016Conference paper (Refereed)
    Abstract [en]

    Today, many small aerodromes struggle withfinancial difficulties, and a large cost is air traffic control.Remote tower centers, which remotely provide air traffic servicesto aerodromes, can help reduce this cost. Each center maycontain a number of remote tower modules, where each moduleis manned by a controller that can handle one or moreaerodromes. In this paper we present the remote tower centerconcept and develop a model that optimizes the assignment ofairports to the remote tower modules. Computational results fora possible scenario based on real data for Swedish airports arepresented.

    A framework for integrated terminal airspace design2019In: Aeronautical Journal, ISSN 0001-9240, Vol. 123, no 1263, p. 567-585Article in journal (Refereed)
    Abstract [en]

    Route planning and airspace sectorisation are two central tasks in air traffic management. Traditionally, the routing and sectorisation problems were considered separately, with aircraft trajectories serving as input to the sectorisation problem and, reciprocally, sectors being part of the input to the path finding algorithms. In this paper we propose a simultaneous design of routes and sectors for a transition airspace. We compare two approaches for this integrated design: one based on mixed integer programming, and one Voronoi-based model that separates potential "hotspots" of controller activity resulting from the terminal routes. We apply our two approaches to the design of Stockholm Terminal Maneuvering Area.

    Automatic Design of Aircraft Arrival Routes with Limited Turning Angle2016In: 16th Workshop on Algorithmic Approaches for Transportation Modelling, Optimization, and Systems (ATMOS 2016) / [ed] Marc Goerigk and Renato Werneck, Dagstuhl, Germany, 2016, Vol. 54, p. 9:1-9:13Conference paper (Refereed)
    Abstract [en]

    We present an application of Integer Programming to the design of arrival routes for aircraft in a Terminal Maneuvering Area (TMA). We generate operationally feasible merge trees of curvature-constrained routes, using two optimization criteria: (1) total length of the tree, and (2) distance flown along the tree paths. The output routes guarantee that the overall traffic pattern in the TMA can be monitored by air traffic controllers; in particular, we keep merge points for arriving aircraft well separated, and we exclude conflicts between arriving and departing aircraft. We demonstrate the feasibility of our method by experimenting with arrival routes for a runway at Arlanda airport in the Stockholm TMA. Our approach can easily be extended in several ways, e.g., to ensure that the routes avoid no-fly zones.

    Optimized Adaptive Streaming of Multi-video Stream Bundles2017In: IEEE transactions on multimedia, ISSN 1520-9210, E-ISSN 1941-0077, Vol. 19, no 7, p. 1637-1653Article in journal (Refereed)
    Abstract [en]

    In contrast to traditional video, multi-view video streaming allows viewers to interactively switch among multiple perspectives provided by different cameras. One approach to achieve such a service is to encode the video from all of the cameras into a single stream, but this has the disadvantage that only a portion of the received video data will be used, namely that required for the selected view at each point in time. In this paper, we introduce the concept of a multi-video stream bundle that consists of multiple parallel video streams that are synchronized in time, each providing the video from a different camera capturing the same event or movie. For delivery we leverage the adaptive features and time-based chunking of HTTP-based adaptive streaming, but now employing adaptation in both content and rate. Users are able to change their viewpoint on-demand and the client player adapts the rate at which data are retrieved from each stream based on the users current view, the probabilities of switching to other views, and the users current bandwidth conditions. A crucial component of such a system is the prefetching policy. For this we present an optimization model as well as a simpler heuristic that can balance the playback quality and the probability of playback interruptions. After analytically and numerically characterizing the optimal solution, we present a prototype implementation and sample results. Our prefetching and buffer management solution is shown to provide close to seamless playback switching when there is sufficient bandwidth to prefetch the parallel streams.

    Capacity-Driven Automatic Design of Dynamic Aircraft Arrival Routes2018In: 2018 IEEE/AIAA 37TH DIGITAL AVIONICS SYSTEMS CONFERENCE (DASC), IEEE , 2018, p. 1194-1202Conference paper (Refereed)
    Abstract [en]

    We present a Mixed-Integer Programming framework for the design of aircraft arrival routes in a Terminal Maneuvering Area (TMA) that guarantee temporal separation of aircraft. The output routes constitute operationally feasible merge trees, and guarantee that the overall traffic pattern in the TMA can be monitored by air traffic controllers; in particular, we ensure that all aircraft on the arrival routes are separated in time and all merge points are spatially separated. We present a proof of concept of our approach, and demonstrate its feasibility by experiments for arrival routes during one hour at Stockholm TMA.

    Controller-Pilot Data Link Communication Security2018In: Sensors, ISSN 1424-8220, E-ISSN 1424-8220, Vol. 18, no 5, article id 1636Article in journal (Refereed)
    Abstract [en]

    The increased utilization of the new types of cockpit communications, including controller pilot data link communications (CPDLC), puts the airplane at higher risk of hacking or interference than ever before. We review the technological characteristics and properties of the CPDLC and construct the corresponding threat model. Based on the limitations imposed by the system parameters, we propose several solutions for the improved security of the data messaging communication used in air traffic management (ATM). We discuss the applicability of elliptical curve cryptography (ECC), protected aircraft communications addressing and reporting systems (PACARs) and the Host Identity Protocol (HIP) as possible countermeasures to the identified security threats. In addition, we consider identity-defined networking (IDN) as an example of a genuine security solution which implies global changes in the whole air traffic communication system.

    A Step Towards Remote Tower Center Deployment: Optimizing Staff Scheduling2017In: 11th USA/Europe Air Traffic Management Research and Development Seminar 2015: Proceedings, The European Organisation for the Safety of Air Navigation , 2017Conference paper (Refereed)
    Abstract [en]

    —Remote Tower Service (RTSs) is one of the technological and operational solutions delivered for deployment by the Single European Sky ATM Research (SESAR) Programme. This new concept fundamentally changes how operators provide Air Traffic Services, as it becomes possible to control several airports from a single remote center. In such settings an air traffic controller works at a so-called “multiple position” in the remote center, that is, he/she handles two or more airports from one Remote Tower Module (RTM), i.e the controller working position. In this paper, we present an optimization framework for the traffic management at five Swedish airports that were chosen for remote operation using a Remote Tower Center designed to serve a number of airports. We highlight the problems experienced with real airport schedules, and present optimal assignments of the airports to the RTMs. We consider both scheduled traffic and special (non-scheduled) traffic at these five airports.

    Scheduling Air Traffic Controllers at the Remote Tower Center2017In: Digital Avionics Systems Conference (DASC), 2017 IEEE/AIAA 36th, IEEE, 2017Conference paper (Refereed)

    Remote Tower Service (RTS) is one of the technological and operational solutions delivered for deployment by the Single European Sky ATM Research (SESAR) Programme. This new concept fundamentally changes how operators provide Air Traffic Services, as it becomes possible to control several airports from a single remote center. In such settings an air traffic controller works at a so-called “multiple position” at the Remote Tower Center (RTC), which means that he/she can handle two or more airports from one Remote Tower Module (controller working position). In this paper, we present an optimization framework designed for automation of staff planning at the RTC. We highlight the problems experienced with real airport flight schedules, and present optimal shift assignments for five Swedish airports that were chosen for remote operation.

    isBF: Scalable in-packet bloom filter based multicast2015In: Computer Communications, ISSN 0140-3664, E-ISSN 1873-703X, Vol. 70, p. 79-85Article in journal (Refereed)
    Abstract [en]

    Bloom filter (BF) based forwarding was proposed recently in several protocol alternatives to IP multicast. Some of these protocols avoid the state in intermediate routers and leave the burden of scalability management to the multicast source and end-hosts. Still, the existing BF-based protocols have scalability limitations and require explicit network management as well as non-trivial functionality from the network components. In this work we address the scalability limitations of the BF-based forwarding protocols by partitioning endhosts into clusters. We propose several algorithms to do the partitioning so as to decrease the overall traffic in the network. We evaluate our algorithms in a real Internet topology, demonstrating the ability of the proposed design to save up to 70% of traffic volume in the large-scale topology for big groups of subscribers, and up to 30% for small groups.

    CONVEX SECTORIZATION-A NOVEL INTEGER PROGRAMMING APPROACH2017In: 2017 INTEGRATED COMMUNICATIONS, NAVIGATION AND SURVEILLANCE CONFERENCE (ICNS), IEEE , 2017Conference paper (Other academic)
    Abstract [en]

    We present a MIP-based airspace sectorization framework for Terminal Maneuvering Areas that can enforce convex sectors. The approach integrates an airspace complexity representation, and the resulting sectorizations have a balanced taskload. We present results for Stockholm TMA; and compare our results to convex sectorizations obtained by enumerating all possible topologies for a given number of sectors.
