  1. Using group anonymity to hide the identity of VoIP mobile users communicating over hybrid networks while preserving quality of service

    This paper proposes an anonymity framework for Voice-over-IP communications without violating Quality of Service constraints. A device forwards its packets anonymously via its clusterhead and through the infrastructure network to the peer's clusterhead, which uses broadcasting to deliver packets anonymously to the peer device. Devices discover their peer's clusterheads without jeopardizing unlinkability using a Registry in which each device adds its ID and that of its clusterhead in such a way that no one other than its contacts can recognize their meaning.

    In this work, a latest comparative review is presented on the clustering techniques employed for efficient data aggregation in target tracking applications along with their gains and issues. Simulation results reveal that the efficacy and validity of these clustering-based data aggregation algorithms are limited to specific sensing situations only, while failing to exhibit adaptive behavior in other various environmental conditions.

  3. Modeling and performance analysis of dynamic spectrum sharing between DSRC and Wi-Fi systems

    The dynamic spectrum sharing in the 5.9-GHz band can significantly enhance the performance of Wi-Fi communication without excessively degrading the DSRC system. The Cisco's proposal prefers to protect the DSRC profit while Qualcomm favours Wi-Fi exclusively.

  4. Subcarrier grouping with environmental sensing for MIMO-OFDM systems over correlated double-selective fading channels

    In high–mobility scenarios, the time–varying transmission environments and/or the relative moving velocity lead to fast time–varying channels. In this paper, adaptive subcarrier grouping scheme is designed to suit the fast time–varying multiple-input multiple-output orthogonal frequency division multiplexing channels. Theoretical and simulation results show that sparse scattering, lower SNR, and lower velocity as well as properly large antenna number are matched with larger subcarrier group size. In addition, higher antenna number will not bring additional gain to the subcarrier grouping size.

  5. Three-path successive relaying protocol with blind inter-relay interference cancellation and cooperative non-coherent detection

    To achieve full-duplex connectivity in scenarios with accuracy of instantaneous channel state information, we proposed a double listening three-path successive relaying (DL3PSR) protocol with blind inter-relay interference cancellation and cooperative non-coherent detection techniques. Moreover, joint forward and backward decoding strategy is proposed to improve the robustness of data detection by independent version of the original data. The detection threshold, bit error probability, and achievable rate of three-path successive relaying are theoretically obtained.
