    Frequency Resource Sharing and Allocation Scheme Based on Coalition Formation Game in Hybrid D2D-Cellular Network by Qing Ou, Rongqing Zhang, Xi Luan, Yuxin Cheng, Jun Wu, Jianjun Wu

    Published 2015-01-01
    “…A distributed cooperation scheme on frequency resource sharing is proposed to improve the quality of service (QoS) in device-to-device (D2D) communications underlaying cellular networks. Specifically, we formulate the resource allocation problem as a coalition formation game with transferable utility, in which all users have the incentive to cooperate with some others and form a competitive group to maximize the probability of obtaining their favorite spectrum resources. …”

    Tractable yet effective approximation to directional antenna array for millimeter-wave networks by Na DENG, Haichao WEI

    Published 2018-12-01
    “…The complexity of the actual antenna pattern imposes restrictions on investigating the benefits of directional antenna arrays in large-scale networks.Hence,a novel multi-level flat-top antenna pattern was proposed to approximate and simplify the actual one and was applied in millimeter-wave cellular networks for performance analysis.To fully characterize the impact of the directional antenna array on the user performance,stochastic geometry was adopted to establish an analytical framework for millimeter-wave cellular networks and derive the coverage probability and transmission rate of the typical user with the proposed multi-level flat-top antenna pattern,including the exact and bounding expressions.The simulation results show that the proposed antenna pattern provides a better tradeoff between the accuracy and tractability than previous patterns.…”

    Data Offloading Over Vehicular DTNs: City-Wide Feasibility Study in Nagoya by Takamasa Higuchi, Lei Zhong, Ryokichi Onishi

    Published 2024-01-01
    “…The increasing network traffic from connected vehicles is putting a strain on the limited bandwidth resources of cellular networks. Delay-tolerant networking (DTN) over vehicle-to-vehicle (V2V) communications has been considered as an effective means of offloading the cellular data traffic, while its quantitative performance in urban road traffic remains unclear in many aspects. …”
