    PowerNap: An Energy Efficient MAC Layer for Random Routing in Wireless Sensor Networks

    Idle-listening is the biggest challenge for energy-efficiency and longevity of multihop Wireless Sensor Network (WSN) deployments. While existing coordinated sleep/wakeup scheduling protocols eliminate idle-listening for simple traffic pat-terns, they are unsuitable to handle the complex traffic patterns of the random routing protocols. The authors present a novel coordinated sleep/wakeup protocol...

    Detecting Anomalies in Active Insider Stepping Stone Attacks

    Network attackers frequently use a chain of compromised intermediate nodes to attack a target machine and maintain anonymity. This chain of nodes between the attacker and the target is called a stepping stone chain. Various classes of algorithms have been proposed to detect stepping stones, timing correlation based algorithms being...

    Progress Toward Quantum Communications Networks: Opportunities and Challenges

    Quantum communications is fast becoming an important component of many applications in quantum information science. Sharing quantum information over a distance among geographically separated nodes using photonic qubits requires a reconfigurable transparent networking infrastructure that can support quantum information services. Using Quantum Key Distribution (QKD) as an example of a...

    Optical Networking for Quantum Key Distribution and Quantum Communications

    Modern optical networking techniques have the potential to greatly extend the applicability of quantum communications by moving beyond simple point-to-point optical links, and by leveraging existing fiber infrastructures. The authors experimentally demonstrate many of the fundamental capabilities that are required. These include optical-layer multiplexing, switching, and routing of quantum signals;...

    Dense Wavelength Multiplexing of 1550 Nm QKD With Strong Classical Channels in Reconfigurable Networking Environments

    To move beyond dedicated links and networks, quantum communications signals must be integrated into networks carrying classical optical channels at power levels many orders of magnitude higher than the quantum signals themselves. The authors demonstrate transmission of a 1550-nm quantum channel with up to two simultaneous 200-GHz spaced classical telecom...

    Realistic Modeling of Tactical Networks With Multi-Level Security in VAN Testbeds

    Testing of applications for tactical MANETs poses a special technical challenge due to the difficulty of conducting experiments in an ad hoc network environment at a scale larger than a few nodes. One approach is to conduct experiments in Virtual Ad hoc Network (VAN) testbeds that can imitate a tactical...

    Engineering for Growth in the Middle East

    Qatar ranks among the top three countries in terms of the numbers of computer, Internet, wireline, wireless, and broadband. Combination of continued growth and increased competition creates opportunities and challenges for Qatar Tel (Qtel). But the increased competition also puts more pressure on Qtel to improve its business efficiency, which...

    Plan-To-Provision: Secure A Sound Business Foundation

    The plan-to-provision process tends to be out of sight, out of mind. In spite of the billions of dollars being spent on modernization, it often fails to attract operators attention the way more prominent and measurable processes do, like order-to-cash. This white paper argues that plan-to-provision should not be allowed...

    Enhancing Congestion Control With Adaptive Per-Node Airtime Allocation for Wireless Sensor Networks

    Wireless sensor networks are usually equipped with single radio interfaces where a sensor node can participate in only one transmission at a time. As a result, a node's airtime is "Shared" by multiple flows that pass through the node. Although it is practically important, how to effectively allocate airtime among...

    Dynamic Buffering Control Scheme for Mobile Handoff

    In a mobile environment, as a mobile node moves from one point of attachment to another during an ongoing application session it is subjected to packet loss due to network and link layer transition. Such packet loss affects the quality of ongoing communication session such as interactive VoIP traffic and...

    Route Optimization for Proxy Mobile IPv6 in IMS Network

    Localized mobility protocols are designed to address many of the drawbacks such as additional signaling and over-the-air tunnel overhead associated with global mobility protocols like Mobile IPv4 and Mobile IPv6. Proxy Mobile IPv6 is one such network controlled localized protocol defined in the IETF. Although Proxy Mobile IPv6 can resolve...
