    Using UHF Connectivity to Off-Load VHF Messaging in Tactical MANETs

    Future mobile tactical networks are being developed to support an increased variety of data services (e.g. Blue Force Tracking, intelligence image or video reporting) in addition to the more traditional voice services. Such networks rely on an IP-based MANET stack, running over a UHF (Ultra-High Frequency) radio interface. Unlike legacy...

    Application Control for Fast Adaptive Error Resilient H.264/AVC Streaming Over IP Wireless Networks

    Following the joint source and channel coding paradigm, the authors propose in this paper an application controlling strategy to allow fast adaptation of multimedia transmission to the impairments of an IP wireless network. To this purpose, a semi-analytical prediction algorithm of the video stream Perceived Quality of Service (PQoS) expressed...

    Affine Masking Against Higher-Order Side Channel Analysis

    In the last decade, an effort has been made by the research community to find efficient ways to thwart Side Channel Analysis (SCA) against physical implementations of cryptographic algorithms. A common countermeasure for implementations of block ciphers is Boolean masking which randomizes by the bitwise addition of one or several...

    Optimisation of Multimedia Over Wireless IP Links Via X-Layer Design

    This paper presents the solution designed by the ICT FP7 OPTIMIX project to enable enhanced multimedia streaming in a point to multi-point context on wireless heterogeneous systems. OPTIMIX approach is to introduce new control blocks, i.e., controllers and observer, to efficiently handle the optimization of the multimedia transmissions. The design...

    Maximizing the Number of Accepted Flows in TDMA-Based Wireless Ad Hoc Networks Is APX-Complete

    Wireless networks are becoming attractive thanks to the ease and low cost of their installation. Moreover, they provide high capacity bandwidth and support client mobility. They tend to replace wired networks in urban areas. Thus, they have to support different multi-hop QoS and priority flows. Contrary to wired networks, in...
