    Notes on the Public Sphere on a National and Post-National Axis: Journalism and Freedom of Expression in Turkey2010In: Global Media and Communication, ISSN 1742-7665, Vol. 6, no 2, p. 177-197Article in journal (Refereed)
    Abstract [en]

    Since Turkey became a candidate for the European Union in 1999, democratic rights and freedom of expression have been key issues in discourses surrounding EUTurkey relations. Discussions on these questions often centre on state censorship and legislative constraints. The role of the media themselves, however, and the deeply-ingrained elements and historically-contingent norms and practices within public culture that shape the public sphere, have received a significantly lower level of attention. Despite recent legislative changes towards greater freedom of expression, major hurdles that limit democratic rights and freedoms persist in practice, as highlighted by the judicial trial (and the subsequent murder in January 2007) of the Armenian-Turkish journalist Hrant Dink. The police raid of Nokta magazine in 2007 is another case in point. The purpose of this article is to discuss current questions related with freedom of expression and tolerance of diversity in the Turkish media based on in-depth interviews with journalists and with the Dink and Nokta cases as examples; and to offer critical reflections on the public sphere in Turkey in its current state

    Cultural Citizenship and the Communicative Space of Mediated Sexual Expressivity2011In: International Journal of Media and Cultural Politics, ISSN 1740-8296, E-ISSN 2040-0918, Vol. 7, no 2, p. 209-224Article in journal (Refereed)
    Abstract [en]

    The role of pornography in contemporary media societies constitutes one of the underresearched areas in media and communication studies. The purpose of this article is to explore the potentiality latent in the user-porn-related Internet domains, blogs and forums – as extensions of offline agency and sociality – for motivating communicative action and engagement with civic practice in various forms. In this study, we utilize an interdisciplinary approach that feeds from social, political and cultural theory and we take ‘self-pornographic pursuit as cultural citizenship’ as a paradigmatic intersection. The discussion is based on our analysis of a variety of expressive venues (some purely online, some amalgamated with the offline) over the course of our preliminary research. Of these, we refer to two Swedish examples: Bodycontact, a sexual dating site, and Dirty Diaries, a feminist film project and the adjacent website, as illustrative of the theoretical arguments presented throughout our discussion.

    The Encapsulated vs. the Cosmopolitan Self? : Towards a Phenomenological Understanding of Mediatized Communication and Complicit Surveillance2012Conference paper (Refereed)
    Abstract [en]

    Mediatization refers to a meta-process whereby social life in its totality is (re)embedded in and saturated with mediated processes. This paper addresses the relationship between two theoretically diverging, yet socially intertwined, realms pertaining to various mediatization patterns: cosmopolitanism and surveillance. Mediatization implies increasing opportunities for ‘extending the self’, experienced in terms of mediated proximity, immediacy and boundary transgression – ultimately sustaining a more cosmopolitan outlook of the world. Yet, mediatization also brings growing opportunities for securitization, boundary control and social encapsulation, on behalf of societal institutions as well as individuals and groups. Contemporary forms and extensions of surveillance and cosmopolitanism are increasingly interwoven through the meta-process of mediatization, most recently the social saturation of converging ‘social’ media. This paper suggests that phenomenology, as a heuristic tool, offers a well-contextualized and grounded socio-cultural perspective to grasp the everyday dimensions and subjective moral positionalities ensuing from increased mediatization and related openings and closures

    Form and Content in Numbers: using content analysis to explore changes in form and content on web sites over time2005Conference paper (Other (popular science, discussion, etc.))
    Abstract [en]

    The purpose of this paper is to describe and exemplify a method for analyzing the form and content of web sites. The paper is based on empirical work conducted by myself in late 2004 and beginning of 2005. Using quantitative content analysis I analyzed Swedish university web sites in different versions from 1996 to 2005. The purpose of the analysis was to explore how the form and content of these web sites has changed over time. This paper shows how the analysis was done; focusing on the methodological aspects of, and the different steps in, the analysis. To exemplify what kind of data the analysis yielded, a preliminary short version of the results of the analysis is included. The paper ends with a few examples of how the empirical data may be used in the analysis of how production conditions affect the outcome of the web design processes

    W-NINE: A Two-stage Emulation Platform for Mobile and Wireless Systems2010In: EURASIP Journal on Wireless Communications and Networking, ISSN 1687-1472, E-ISSN 1687-1499, Vol. 2010, p. 1-20Article in journal (Refereed)
    Abstract [en]

    More and more applications and protocols are now running on wireless networks. Testing         the implementation of such applications and protocols is a real challenge as the position of the mobile terminals and environmental effects strongly affect the overall performance. Network emulation is often perceived as a good trade-off between experiments on operational wireless networks and discrete-event simulations on Opnet or ns-2. However, ensuring repeatability and realism in network emulation while taking into account mobility in a wireless environment is very difficult. This paper proposes a network emulation platform, called W-NINE, based on off-line computations preceding online pattern-based traffic shaping. The underlying concepts of repeatability, dynamicity, accuracy, and realism are defined in the emulation context. Two different simple case studies illustrate the validity of our approach with respect to these concepts.

    Aggregation-Based Gossip for Certificate TransparencyOther (Other academic)
    Abstract [en]

    Certificate Transparency (CT) is a project that mandates public logging of TLS certificates issued by certificate authorities. While a CT log is designed to be trustless, it relies on the assumption that every client sees and cryptographically verifies the same log. The solution to this problem is a gossip mechanism that ensures that clients share the same view of the logs. Despite CT being added to Google Chrome, no gossip mechanism is pending wide deployment. We suggest an aggregation-based gossip mechanism that passively observes cryptographic material that CT logs emit in plaintext, aggregating at packet processors and periodically verifying log consistency off-path. Based on 20 days of RIPE Atlas measurements that represents clients from 3500 autonomous systems and 40% of the IPv4 space, our proposal can be deployed incrementally for a realistic threat model with significant protection against undetected log misbehavior. We also discuss how to instantiate aggregation-based gossip on a variety of packet processors, and show that our P4 and XDP proof-of-concepts implementations run at line-speed.

    Intermediate report about wireless secrecy metrics and preliminary algorithms: NEWCOM++ DR.A.12008Report (Refereed)
    Abstract [en]

    This deliverable provides a first overview of the state of the art on wireless security metrics and algorithms,

    which are particularly very important with respect to the intrinsic vulnerability of the wireless

    medium. The first part deals with building practical physical layer information-theoretic secure schemes.

    Indeed, Shannon formalized the concepts of capacity (as a transmission efficiency measure) and equivocation

    (as a measure of secrecy). While the concept of capacity has been extended to fading channels

    with the introduction of concepts like the outage capacity or the ergodic capacity, similar paths are yet to

    be developed concerning equivocation. In the second part, we present a taxonomy of threats for wireless

    networks, and particularly for wireless sensor networks, in terms of the affected protocol layers. Besides,

    an overview to attack tree and attack graph techniques as formal means for describing and measuring

    vulnerabilities and thus also for assessing also the security level of wireless sensor networks is provided.

    Finally, an overview to suitable security concepts for wireless networks is given

    Practical Considerations for Channel Assignment in Wireless Mesh Networks2010In: GLOBECOM Workshops (GC Wkshps), 2010 IEEE, IEEE , 2010, p. 763-767Conference paper (Refereed)
    Abstract [en]

    Abstract--- In multi-radio wireless mesh networks (WMNs) several radios can operate within one node simultaneously on different channels. Due to frequency selective fading and varying output powers of WLAN cards the received signal strength on channels in the U-NII band can differ by several dB. Furthermore, power leakage from neighboring channels in the frequency spectrum can cause adjacent channel interference (ACI). Using a IEEE 802.11a testbed, we experimentally evaluate the achievable throughput of a multi-radio mesh network in a string topology under the impact of ACI and channel heterogeneity. Our results show that for low PHY rates the channel separation is a good indicator for throughput. However, for high PHY rates the propagation properties of a specific channel also need to be considered. Based on the results we provide recommendations for designing channel assignment algorithms for IEEE 802.11-based WMNs

    Fair Optimization of Mesh-Connected WLAN Hotspots2015In: Wireless Communications & Mobile Computing, ISSN 1530-8669, E-ISSN 1530-8677, Vol. 15, no 5, p. 924-946Article in journal (Refereed)
    Abstract [en]

    In Wireless mesh networks mesh access points (MAPs) forward traffic wirelessly towards users or Internet gateways. A user device usually connects to the MAP with the strongest signal, as such MAP should guarantee the best quality of service. However, this connection policy may lead to: (i) unfairness towards users that are distant from gateways; (ii) uneven distribution of users to MAPs; and (iii) inefficient use of network paths. We present a new model and solution approach to the problem of assigning users to MAPs and routing the data within the mesh network with the objective of providing max–min fair throughput. The problem is formulated as a mixed-integer linear programming problem (MILP). Because of the inherent complexity of the problem, real size instances cannot be solved to optimality within the time limits for online optimization. Therefore, we propose an original heuristic solution algorithm for the resulting MILP. Both numerical comparisons and network simulations demonstrate the effectiveness of the proposed heuristic. For random networks, the heuristic achieves 98% of the optimal solution. Network simulations show that in medium-sized networks, the number of users with at least 1Mbit/s minimum end-to-end rate increases by 550% when compared with the classical signal-strength based association.
