    Scheduling Advantages of Network Coded Storage in Point-to-Multipoint Networks

    The authors consider scheduling strategies for Point-to-MultiPoint (PMP) Storage Area Networks (SANs) that use Network Coded Storage (NCS). In particular, they present a simple SAN system model, two server scheduling algorithms for PMP networks, and analytical expressions for internal and external blocking probability. They point to select scheduling advantages in...

    When Does Relay Transmission Give a More Secure Connection in Wireless Ad Hoc Networks?

    Relay transmission can enhance coverage and throughput, while it can be vulnerable to eavesdropping attacks due to the additional transmission of the source message at the relay. Thus, whether or not one should use relay transmission for secure communication is an interesting and important problem. In this paper, the authors...

    Wireless Physical Layer Security with Imperfect Channel State Information: A Survey

    Physical layer security is an emerging technique to improve the wireless communication security, which is widely regarded as a complement to cryptographic technologies. To design physical layer security techniques under practical scenarios, the uncertainty and imperfections in the channel knowledge need to be taken into consideration. This paper provides a...

    Reporting an Experience on Design and Implementation of e-Health Systems on Azure Cloud

    Electronic Health (e-Health) technology has brought the world with significant transformation from traditional paper-based medical practice to Information and Communication Technologies (ICT)-based systems for automatic management (storage, processing, and archiving) of information. Traditionally e-Health systems have been designed to operate within stovepipes on dedicated networks, physical computers, and locally managed...

    Centralized and Cooperative Transmission of Secure Multiple Unicasts Using Network Coding

    The authors introduce a method for securely delivering a set of messages to a group of clients over a broadcast erasure channel where each client is interested in a distinct message. Each client is able to obtain its own message but not the others'. In the proposed method the messages...

Each client is privileged for receiving an arbitrary subset of the messages over a broadcast erasure channel, which generalizes scenario of a previous work. They propose a method for secretly delivering each message to its privileged...

    Enhancing Secrecy with Sectorized Transmission in Decentralized Wireless Networks

    In this paper, the authors combine sectorized transmission with artificial noise to establish secrecy in decentralized wireless networks. The locations of the legitimate nodes and the eavesdroppers are both modeled by homogeneous Poisson point processes. Using sectorized antennas, each legitimate transmitter sends an information signal in the sector which contains...

    DSTBC Based DF Cooperative Networks in the Presence of Timing and Frequency Offsets

    In Decode-and-Forward (DF) relaying networks, the received signal at the destination may be affected by multiple impairments such as multiple channel gains, Multiple Timing Offsets (MTOs), and Multiple Carrier Frequency Offsets (MCFOs). This paper proposes novel optimal and sub-optimal Minimum Mean-Square Error (MMSE) receiver designs at the destination node to...

    Analytical Evaluation of Coverage-Oriented Femtocell Network Deployment

    This paper proposes a coverage-oriented femtocell network deployment scheme, in which the femtocell Base Stations (BSs) can decide whether to be active or inactive depending on their distances from the macrocell BSs. Specifically, as the areas close to the macrocell BSs already have satisfactory cellular coverage, the femtocell BSs located...

    On the Physical Layer Security in Large Scale Cellular Networks

    This paper studies the information-theoretic secrecy performance in large-scale cellular networks based on a stochastic geometry framework. The locations of both base stations and the mobile users are modeled as independent two-dimensional Poisson point processes. The authors consider a key feature of the cellular network, namely, information exchange between base...
