  1. Track fusion based on threshold factor classification algorithm in wireless sensor networks

    Focusing on the accuracy of target tracking in wireless sensor networks, we propose an improved threshold factor track classification algorithm. The algorithm extracts the motion model according to the intrinsic properties of the target. It updates the iterative center according to the real-time motion state of the moving target and timely filters out the weak correlated or uncorrelated data.

    This paper proposes a hybrid cell association scheme that stresses the importance of combined metrics in a two-tier network. The high-priority user equipments (UEs) associate with the tier that gives the maximum channel gain being higher than a given threshold, while the low-priority UEs association is based on the maximum joint metrics (channel gain, channel access probabilities of low-priority UEs and high-priority UEs). Simulations and analysis show that the proposed hybrid channel gain prioritized access-aware scheme can significantly improve the network performance and load balancing fairness.

  3. QoS-Aware MAC protocols utilizing sectored antenna for wireless sensor networks-based smart grid applications

    In this paper, QoS-aware omnidirectional antenna-based MAC (QODA-MAC) and QoS-aware four-sectored antenna-based MAC (QFSA-MAC) protocols are proposed to meet the requirements of smart grid applications. The aim of the proposed approaches is to increase channel utilization with efficient service differentiation considering traffic flows with different requirements as well as providing reliable and fast delivery of data.

  4. Effects of pointing errors and channel fading on the performance of free-space optically-preamplified PPM systems

    We study the impact of pointing errors and channel fading on the performance of free-space, optically-preamplified, M-ary PPM systems for both inter-satellite, and inter-building links. The channel fading models considered for inter-buildings links are the log-normal and gamma-gamma models. We provide the error probability as a function of the average signal-to-noise ratio per bit for both types of links. We also provide the power penalties for different scintillation indexes and pointing jitters at bit error probabilities of 10−4 and 10−9.

  5. Provably secure strong designated verifier signature scheme based on coding theory

    We present an efficent code-based Strong Designated Verifier Signature scheme as a post quantum signature scheme in which its security relies on hard problems in the coding theory. Also, we demonstrate the unforgeability of our scheme under a chosen message attack in the Random Oracle model. Our work, to the best of our knowledge, is the first provable secure strong designated verifier signature scheme based on the coding theory.
