  text: In \emph{bandwidth allocation games} (BAGs), the strategy of a player consists
    of various demands on different resources. The player's utility is at most the
    sum of these demands, provided they are fully satisfied. Every resource has a
    limited capacity and if it is exceeded by the total demand, it has to be split
    between the players. Since these games generally do not have pure Nash equilibria,
    we consider approximate pure Nash equilibria, in which no player can improve her
    utility by more than some fixed factor $\alpha$ through unilateral strategy changes.
    There is a threshold $\alpha_\delta$ (where $\delta$ is a parameter that limits
    the demand of each player on a specific resource) such that $\alpha$-approximate
    pure Nash equilibria always exist for $\alpha \geq \alpha_\delta$, but not for
    $\alpha < \alpha_\delta$. We give both upper and lower bounds on this threshold
    $\alpha_\delta$ and show that the corresponding decision problem is ${\sf NP}$-hard.
    We also show that the $\alpha$-approximate price of anarchy for BAGs is $\alpha+1$.
    For a restricted version of the game, where demands of players only differ slightly
    from each other (e.g. symmetric games), we show that approximate Nash equilibria
    can be reached (and thus also be computed) in polynomial time using the best-response
    dynamic. Finally, we show that a broader class of utility-maximization games (which
    includes BAGs) converges quickly towards states whose social welfare is close
    to the optimum.

  text: Inter-datacenter transfers of non-interactive but timely large flows over
    a private (managed) network is an important problem faced by many cloud service
    providers. The considered flows are non-interactive because they do not explicitly
    target the end users. However, most of them must be performed on a timely basis
    and are associated with a deadline. We propose to schedule these flows by a centralized
    controller, which determines when to transmit each flow and which path to use.
    Two scheduling models are presented in this paper. In the first, the controller
    also determines the rate of each flow, while in the second bandwidth is assigned
    by the network according to the TCP rules. We develop scheduling algorithms for
    both models and compare their complexity and performance.

  text: 'Abstract We study the problem of bandwidth allocation with multiple interferences.
    In this problem the input consists of a set of users and a set of base stations.
    Each user has a list of requests, each consisting of a base station, a frequency
    demand, and a profit that may be gained by scheduling this request. The goal is
    to find a maximum profit set of user requests S that satisfies the following conditions:
    (i) S contains at most one request per user, (ii) the frequency sets allotted
    to requests in S that correspond to the same base station are pairwise non-intersecting,
    and (iii) the QoS received by any user at any frequency is reasonable according
    to an interference model. In this paper we consider two variants of bandwidth
    allocation with multiple interferences. In the first each request specifies a
    demand that can be satisfied by any subset of frequencies that is large enough.
    In the second each request specifies a specific frequency interval. Furthermore,
    we consider two interference models, multiplicative and additive. We show that
    these problems are extremely hard to approximate if the interferences depend on
    both the interfered and the interfering base stations. On the other hand, we provide
    constant factor approximation algorithms for both variants of bandwidth allocation
    with multiple interferences for the case where the interferences depend only on
    the interfering base stations. We also consider a restrictive special case that
    is closely related to the Knapsack problem. We show that this special case is
    NP-hard and that it admits an FPTAS. '

  text: 'Max-min fairness (MMF) is a widely known approach to a fair allocation of
    bandwidth to each of the users in a network. This allocation can be computed by
    uniformly raising the bandwidths of all users without violating capacity constraints.
    We consider an extension of these allocations by raising the bandwidth with arbitrary
    and not necessarily uniform time-depending velocities (allocation rates). These
    allocations are used in a game-theoretic context for routing choices, which we
    formalize in progressive filling games (PFGs).We present a variety of results
    for equilibria in PFGs. We show that these games possess pure Nash and strong
    equilibria. While computation in general is NP-hard, there are polynomial-time
    algorithms for prominent classes of Max-Min-Fair Games (MMFG), including the case
    when all users have the same source-destination pair. We characterize prices of
    anarchy and stability for pure Nash and strong equilibria in PFGs and MMFGs when
    players have different or the same source-destination pairs. In addition, we show
    that when a designer can adjust allocation rates, it is possible to design games
    with optimal strong equilibria. Some initial results on polynomial-time algorithms
    in this direction are also derived. '

  text: We introduce the concept of budget games. Players choose a set of tasks and
    each task has a certain demand on every resource in the game. Each resource has
    a budget. If the budget is not enough to satisfy the sum of all demands, it has
    to be shared between the tasks. We study strategic budget games, where the budget
    is shared proportionally. We also consider a variant in which the order of the
    strategic decisions influences the distribution of the budgets. The complexity
    of the optimal solution as well as existence, complexity and quality of equilibria
    are analysed. Finally, we show that the time an ordered budget game needs to convergence
    towards an equilibrium may be exponential.

  text: Today's networks, like the Internet, do not consist of one but a mixture of
    several interconnected networks. Each has individual qualities and hence the performance
    of a network node results from the networks' interplay.We introduce a new game
    theoretic model capturing the interplay between a high-speed backbone network
    and a low-speed general purpose network. In our model, n nodes are connected by
    a static network and each node can decide individually to become a gateway node.
    A gateway node pays a fixed price for its connection to the high-speed network,
    but can utilize the high-speed network to gain communication distance 0 to all
    other gateways. Communication distances in the low-speed network are given by
    the hop distances. The effective communication distance between any two nodes
    then is given by the shortest path, which is possibly improved by using gateways
    as shortcuts.Every node v has the objective to minimize its communication costs,
    given by the sum (SUM-game) or maximum (MAX-game) of the effective communication
    distances from v to all other nodes plus a fixed price \alpha > 0, if it decides
    to be a gateway. For both games and different ranges of \alpha, we study the existence
    of equilibria, the price of anarchy, and convergence properties of best-response
    dynamics.

  text: In this paper we study the potential function in congestion games. We consider
    both games with non-decreasing cost functions as well as games with non-increasing
    utility functions. We show that the value of the potential function $\Phi(\sf
    s)$ of any outcome $\sf s$ of a congestion game approximates the optimum potential
    value $\Phi(\sf s^*)$ by a factor $\Psi_{\mathcal{F}}$ which only depends on the
    set of cost/utility functions $\mathcal{F}$, and an additive term which is bounded
    by the sum of the total possible improvements of the players in the outcome $\sf
    s$. The significance of this result is twofold. On the one hand it provides \emph{Price-of-Anarchy}-like
    results with respect to the potential function. On the other hand, we show that
    these approximations can be used to compute $(1+\varepsilon)\cdot\Psi_{\mathcal{F}}$-approximate
    pure Nash equilibria for congestion games with non-decreasing cost functions.
    For the special case of polynomial cost functions, this significantly improves
    the guarantees from Caragiannis et al. [FOCS 2011]. Moreover, our machinery provides
    the first guarantees for general latency functions.

  text: We study the existence of approximate pure Nash equilibria in weighted congestion
    games and develop techniques to obtain approximate potential functions that prove
    the existence of alpha-approximate pure Nash equilibria and the convergence of
    alpha-improvement steps. Specifically, we show how to obtain upper bounds for
    approximation factor alpha for a given class of cost functions. For example for
    concave cost functions the factor is at most 3/2, for quadratic cost functions
    it is at most 4/3, and for polynomial cost functions of maximal degree d it is
    at at most d + 1. For games with two players we obtain tight bounds which are
    as small as for example 1.054 in the case of quadratic cost functions.

  text: We study the existence of approximate pure Nash equilibriain social context
    congestion games. For any given set of allowed costfunctions F, we provide a threshold
    value μ(F), and show that for theclass of social context congestion games with
    cost functions from F, α-Nash dynamics are guaranteed to converge to α-approximate
    pure Nashequilibrium if and only if α > μ(F).Interestingly, μ(F) is related and
    always upper bounded by Roughgarden’sanarchy value [19].

  text: We discuss a technique to analyze complex infinitely repeated games using
    techniques from the fields of game theory and simulations. Our research is motivated
    by the analysis of electronic markets with thousands of participants and possibly
    complex strategic behavior. We consider an example of a global market of composed
    IT services to demonstrate the use of our simulation technique. We present our
    current work in this area and we want to discuss further approaches for the future.

  text: We consider a multilevel network game, where nodes can improvetheir communication
    costs by connecting to a high-speed network.The n nodes are connected by a static
    network and each node can decideindividually to become a gateway to the high-speed
    network. The goalof a node v is to minimize its private costs, i.e., the sum (SUM-game)
    ormaximum (MAX-game) of communication distances from v to all othernodes plus
    a fixed price α > 0 if it decides to be a gateway. Between gatewaysthe communication
    distance is 0, and gateways also improve othernodes’ distances by behaving as
    shortcuts. For the SUM-game, we showthat for α ≤ n − 1, the price of anarchy is
    Θ (n/√α) and in this rangeequilibria always exist. In range α ∈ (n−1, n(n−1))
    the price of anarchyis Θ(√α), and for α ≥ n(n − 1) it is constant. For the MAX-game,
    weshow that the price of anarchy is either Θ (1 + n/√α), for α ≥ 1, orelse 1.
    Given a graph with girth of at least 4α, equilibria always exist.Concerning the
    dynamics, both games are not potential games. For theSUM-game, we even show that
    it is not weakly acyclic.

  text: In this paper we present and analyze HSkip+, a self-stabilizing overlay network
    for nodes with arbitrary heterogeneous bandwidths. HSkip+ has the same topology
    as the Skip+ graph proposed by Jacob et al. [PODC 2009] but its self-stabilization
    mechanism significantly outperforms the self-stabilization mechanism proposed
    for Skip+. Also, the nodes are now ordered according to their bandwidths and not
    according to their identifiers. Various other solutions have already been proposed
    for overlay networks with heterogeneous bandwidths, but they are not self-stabilizing.
    In addition to HSkip+ being self-stabilizing, its performance is on par with the
    best previous bounds on the time and work for joining or leaving a network of
    peers of logarithmic diameter and degree and arbitrary bandwidths. Also, the dilation
    and congestion for routing messages is on par with the best previous bounds for
    such networks, so that HSkip+ combines the advantages of both worlds. Our theoretical
    investigations are backed by simulations demonstrating that HSkip+ is indeed performing
    much better than Skip+ and working correctly under high churn rates.

  text: 'In this paper, we define and study a new problem, referred to as the Dependent
    Unsplittable Flow Problem (D-UFP). We present and discuss this problem in the
    context of large-scale powerful (radar/camera) sensor networks, but we believe
    it has important applications on the admission of large flows in other networks
    as well. In order to optimize the selection of flows transmitted to the gateway,
    D-UFP takes into account possible dependencies between flows. We show that D-UFP
    is more difficult than NP-hard problems for which no good approximation is known.
    Then, we address two special cases of this problem: the case where all the sensors
    have a shared channel and the case where the sensors form a mesh and route to
    the gateway over a spanning tree.'
