“…The framework is developed in multi user MIMO system in presence of inter stream interference and inter user interference and developed a optimization problem approach based on precoding matrix indicator selection, joint user pairing and RB allocation and considering these parameter optimal scheduling algorithm is elaborated which used to increase throughput of overall system. The simulated results display that it is able to achieve goodthroughput [23].…”

Scarce wireless resources, lead to development of cognitive radio network as a solution to unlicensed users communication in the licensed frequency band. In response to the behavior of licensed users communication, unlicensed users communication need to change from one frequency band to another band. In this communication paradigm, the performance of unlicensed users transmission control protocol gets degraded due to the features of cognitive radio network. To overcome this, several authors suggested quite a few modifications in the existing wireless transport protocol for cognitive radio network environment. This paper gives an overview of different transport protocols used for unlicensed users’ communication in cognitive radio networks.

“…The dynamic packet scheduling problem is quite critical in implementing an efficient utilization of the limited resources in satellite LTE networks [180]- [183], especially for QoS guaranteed multimedia traffic scenarios. Authors in [181] proposed a cross-layer resource management with the constraint of QoS, furthermore, they consider the delay, data rate, and fairness as criteria for optimal resource management method [180], while most researches only consider the delay and data rate. They argue that the scheme can reach better throughput.…”

The explosive growth of various services boosts the innovation and development in terrestrial communication systems for the implementation of the next generation mobile communication networks. However, simply utilizing limited resources in terrestrial communication networks is difficult to support the massive quality of service (QoS) aware requirements and it is hard to guarantee seamless coverage in far remote regions. Leveraging the intrinsic merits of high altitude and the ability of multicasting or broadcasting, satellite communication systems provide an opportunity for novel mobile communication networks with its tight interaction and complementary characteristics to traditional terrestrial networks. It is believed that the convergence of satellite and terrestrial networks can solve the problems existing in current mobile communication systems and make a profound effect on global information dissemination. In this paper, we make a comprehensive survey on the convergence of satellite and terrestrial networks. First, motivations and requirements of satellite-terrestrial network convergence are identified. Then, we summarize related architectures of existing literature, classify the taxonomy of researches on satellite-terrestrial networks, and present the performance evaluation works in different satellite-terrestrial networks. After that, the state-ofthe-art of standardization, projects and the key application areas of satellite-terrestrial networks are also reviewed. Finally, we conclude the survey by highlighting the open issues and future directions.

The rapid growth of not just mobile devices but also Internet of Things (IoT) devices has introduced a new paradigm in mobile networks. This evolution and the continuous need to provide spectrum efficient, high data rates, low latency, and low energy consumption radio access networks have led to the emergence of fifth generation (5G) networks. Due to technical and economical limitations, the satellite air interface is expected to complement the 5G terrestrial air interface in the provision of 5G services including IoT communications. More importantly, it is on this premise that the 5G satellite air interface is expected to provide network access to IoT devices in rural and remote areas termed Internet of Remote Things (IoRT). While this remains an interesting solution, several radio resource management issues exist. One of them, spectrum management, in the 5G satellite as it affects IoRT communications, remains unclear. Hence, the aim of this paper is to investigate and recommend the spectrum management scheme that will be most suitable not only for Human-to-Human communications but also Machine-to-Machine communications in 5G satellite networks. In order to conduct this investigation, a new dynamic scheduling scheme that will be suitable for such a scenario is proposed in this paper. The investigation is conducted through simulations, using throughput, delay, spectral efficiency, and fairness index as the performance metrics.Also, recent studies estimate that approximately 4 billion people still lack access to internet [17]. The economic and technical viabilities of the implementation of terrestrial global coverage remains infeasible not only due to rural and remote areas but also passengers on high-speed trains, speed boats or aircrafts. Hence, the need for the satellite segment to complement the terrestrial network infrastructure in the envisaged 5G communication systems cannot be over emphasized in order to address the limitations of the terrestrial network infrastructure. The satellite components will also be able to support new machine-type communications-based applications and the new 5G system is expected to accommodate diverse RANs to operate together, including satellites [18]. It is also envisaged that the satellite systems can support all the use case scenarios that the terrestrial counterparts will be able to provide [19]. It is indeed well recognized that one of the directions in the evolution of the 5G is towards the concept of Internet of Things (IoT) and it is the concept of smart objects that drives the implementation of this new paradigm [20]. No doubt, the satellite communications systems have the potential to play a crucial role in this 5G framework for different reasons.Firstly, smart objects are often located over a wide geographical area, remote or inaccessible. This scenario of IoT is referred to as the Internet of (Remote) Things (IoRT). In the IoRT scenario, satellite communication systems provide a more cost-effective solution with respect to other terrestrial technologies. Secondly, s...
