Physical layer security (PLS) has been extensively explored as an alternative to
conventional cryptographic schemes for securing wireless links. Many studies have shown …

With explosive growth of high-data-rate applications, more and more energy is consumed in
wireless networks to guarantee quality of service. Therefore, energy-efficient …

As an emerging platform based on ITS, SIoV is promising for applications of traffic
management and road safety in smart cities. However, the endto-end delay is large in store …

Due to the ever-increasing requirements of delay-sensitive and mission-critical applications
in 5G, mobile edge computing is promising to react and support real-time interactive …

In this paper, we study the joint allocation of three types of resources, namely, power,
subcarriers and relay nodes, in multi-relay assisted dual-hop cooperative OFDM systems. All …

The performance in cooperative communication depends on careful resource allocation
such as relay selection and power control, but the traditional centralized resource allocation …

Distributed and efficient resource allocation is critical for fully realizing the benefits of
cooperative communications in large scale communication networks. This paper proposes …

Due to the heterogeneous and resource-constrained characters of Internet of Things (IoT),
how to guarantee ubiquitous network connectivity is challenging. Although LTE cellular …

Driven by the urgent requirement of ubiquitous and reliable coverage for global users, the
low earth orbit (LEO) satellite network has attracted numerous attentions from the academic …

In this paper, the joint power and subcarrier allocation problem is solved in the context of
maximizing the energy-efficiency (EE) of a multi-user, multi-relay orthogonal frequency …
