  1. Towards broadcast redundancy minimization in duty-cycled wireless sensor networks

    Broadcast Redundancy Minimization Scheduling scheme is proposed to minimize the number of broadcast transmissions in duty-cycled wireless sensor networks. It identifies a minimum set of covering nodes and then constructs a forest of sub-trees based on the relationship between each covering node and its corresponding covered nodes. A broadcast tree is constructed ultimately by connecting all sub-trees. The concept of duty transmission (a transmission from a covering node to its receivers) is utilized to reduce unnecessary transmissions.

    In this paper, we proposed a topology evolution model with small-world and scale-free features for the ad hoc network in the ad hoc-cellular network scenario, which is based on the BBV model and the TF mechanism. In the topology evolution process, we take into account the users' residual energy, available channel quality, and the interference of cellular network. The network built by our model has strong robustness against the random nodes failure and small average minimum path length.

  3. Generalized OSTBC-based subcarrier intensity-modulated MIMO optical wireless communication system

    In this study, we analyze an optical wireless communication (OWC) system having a source and a destination node, equipped with multiple transmit and receive apertures, respectively. We utilize generalized orthogonal space-time block codes (OSTBCs) of any arbitrary order and subcarrier intensity modulation scheme for data transmission. The closed-form expression of the approximate average symbol error rate (SER) of multi-aperture-based OWC system is obtained for the generalized OSTBC and an arbitrary M-phase-shift keying constellation. Using the derived SER expression, we analytically evaluate the diversity order and the coding gain of the OWC system with gamma-gamma atmospheric turbulence.

  4. Adaptive time delay estimation algorithm for indoor near-field electromagnetic ranging

    Article first published online: 28 JAN 2016 | DOI: 10.1002/dac.3113

    In this paper, we propose a new adaptive time delay estimation algorithm based on maximum correntropy criterion (MCC) and received signal strength indication (RSSI). The proposed RSSIMCC algorithm estimates the time delay between the electric and magnetic components of low-frequency signals in the near field instead of detecting the phase difference. An inaccurate time delay estimation value obtained according to RSSI is used as the initial time delay of adaptive time delay estimator, which can improve the convergence speed.

  5. Energy-efficient partner selection in cooperative wireless networks: a matching-theoretic approach

    Article first published online: 26 JAN 2016 | DOI: 10.1002/dac.3114

    This paper studies the problem of stable energy-efficient partner selection in cooperative wireless networks. Two polynomial-time complexity matching algorithms based on the stable roommates matching problem are proposed. The first algorithm, denoted Irving's stable matching (ISM), may not always have a stable solution. Therefore, the second algorithm, denoted maximum stable matching (MSM), is proposed to find the maximum number of stable disjoint pairs. Simulation results validate the efficiency of the proposed algorithms in comparison with centralized energy-efficient partner selection as well as other matching algorithms.
