    Joint Optimization for MIMO AF Multiple-Relay Systems With Correlated Channel Uncertainties

    In the paper, the source/relays-pre-coders and destination-equalizer combined optimization is proposed in a dual-hop Multiple-Input Multiple-Output (MIMO) Amplify-and-Forward (AF) multiple-relay system with correlated channel uncertainties in both hops. By taking correlated channel uncertainties into account, a robust transceiver joint design is developed based on the Minimum Mean-Squared Error (MMSE) criterion...

    The Relationship Between Business-Model Innovation and Firm Value: A Dynamic Perspective

    When consistently innovative business-models can give companies a competitive advantage, longitudinal empirical research, which can reflect dynamic business-model changes, has yet to prove a definitive connection. This paper consequently employs a dynamic perspective in conjunction with innovation theory to examine the relationship between the types of business-model innovation and firm...

    SAT-based Verification of Data-Independent Access Control Security Systems

    The Harrison-Ruzzo-Ullman problem is the verification of a set of policy rules, starting from an initial protection matrix, for the reachability of a state in which a generic access right is granted. Three decades ago, it was shown to be undecidable; however, recently Kleiner and Newcomb (KN) used communicating sequential...

    A Mobicast Routing Protocol With Carry-and-Forward in Vehicular Ad-Hoc Networks

    In vehicular networks, safety and comfort applications are two quite different kinds of applications to avoid the emergency traffic accident and enjoy the non-emergency entertainment. The comfort application drives the challenges of new non-emergency entertainments for Vehicular Ad-hoc NETworks (VANETs). The comfort application usually keeps the delay-tolerant capability; that is,...

    An Effective Cancellation Technique of Cochannel Interference Based on Multiuser Detection Scheme for MFSK/FH-SSMA Systems

    The performance of a Multilevel Frequency Shift Keying/Frequency Hopping-Spread Spectrum Multiple Access (MFSK/FH-SSMA) system over a co-channel interference scenario is dependent on multiuser detection schemes. Many investigations have demonstrated huge potential capacity and performance improvement by using multiuser detection schemes. However, their schemes are extremely complex while the total number...

    A Low Propagation Delay Multi-Path Routing Protocol for Underwater Sensor Networks

    The large-scale mobile Underwater Wireless Sensor Network (UWSN) is a useful networking paradigm to explore underwater environments. The characteristics of mobile UWSNs, such as low communication bandwidth, large propagation delay, and floating node mobility are significantly different from wireless sensor networks. In this paper, the authors propose a new efficient...

    A Cross Layer Fast Handover Scheme in VANET

    This paper presents a cross-layer fast handover scheme for VANET, called Vehicular Fast Handover Scheme (VFHS), where the physical layer information is shared with the MAC layer, to reduce the handover delay. The key idea of VFHS is to utilize Oncoming Side Vehicles (OSVs) to collect physical and MAC layers...

    Non-Location-Based Mobile Sensor Relocation in a Hybrid Static-Mobile Wireless Sensor Network

    An inherent concern for a Wireless Sensor Network (WSN) is the unbalanced energy consumption problem, where sensors closer to the sink are more likely to exhaust their energy faster than other nodes. To mitigate this problem, this paper considers including some resource-rich mobile nodes, called mobile data-pumps, to conduct data...

    Data Gathering by Mobile Mules in a Spatially Separated Wireless Sensor Network

    While Wireless Sensor Networks (WSNs) are typically targeted at large-scale deployment, due to many practical or inevitable reasons, a WSN may not always remain connected. This paper considers the possibility that a WSN may be spatially separated into multiple subnetworks. Data gathering, which is a fundamental mission of WSN, thus...
