Millimeter wave (mmWave) communication is a key enabling technology for 5G cellular systems. However, due to mmWave propagation characteristics, link length for very high rates is limited and will likely necessitate the use of relay nodes for longer-range ultra-high-speed backhaul communications. This paper investigates relay selection and scheduling to support high end-to-end throughput in mmWave...
The deployment of small cell base stations within the coverage area of a macrocell base station serves as an important means of increasing energy efficiency. Furthermore, such a deployment also constitutes a key technology for future communication network markets. There is a shortage of research, however, on how to efficiently solve the problem of coverage holes (that is, specific locations or areas...
There are lots of efforts to improve interworking architectures for the purpose of offloading cellular traffic via complementary wireless technologies. Some offer a specific feature and others work on a generic one, and yet there is a need for feature-rich interworking architecture for offloading purposes. This paper proposes a fully integrated, hybrid and Quality of Service aware interworking architecture...
Brain Computer Interface (BCI) has recently gained much popularity due to plethora of its applications. In this paper, we propose a novel system architecture to utilize brain signals for controlling Internet of Things enabled environments. The proposed architecture aids in translating brain signals to commands that interact with or control the environment using IoT actuation networks thus executing...
Research on a new solution supporting low latency, high reliability, and scalability is required to deal with ever-increasing demand for wireless communication. However, it is often restricted due to the fact that setting up experiments needs a considerable amount of effort and cost. To alleviate such difficulties, the WiSHFUL project has been established, which proposes an architecture for flexible...
Due to the new characteristics of ultra-dense networks (UDN), such as high dense deployment of wireless access points (APs), complicated handover signaling processes and irregular coverage, how to achieve mobility support and reduce user's interrupt ratio remain a difficult problem. To address these issues, based on the presented user-centric APs clustering (UCC) network architecture in UDN, a UCC...
In this paper, we implement the Wi-Fi hardware architecture. The core chip designed by the MediaTek Corporation is used to develop its peripheral circuits. The chip supports USB Type and can control the lighting circuit through the APP on the mobile phone, so as to simulate the switch of household electrical appliances. In the future, consumers can purchase home appliances with built-in communication...
Vehicle-to-Everything (V2X) communications encapsulate significant challenges as a result of the vast number of wireless technologies deployed, nodes mobility and large applications range. One of the greatest challenges is to provide adequate QoS guarantees even in this demanding environment. State-of-the-art solutions for QoS provisioning over wireless links are based on cross-layering packet schedulers...
There has been renewed attention given to High Speed Railways (HSR) in the US, in terms of adapting more speed, reliability, increasing passenger capacity and providing passenger centric services. Any future Train-To-Ground (T2G) communication system therefore has to embrace reliable signaling and control-specific needs of HSR, while also catering towards the high performance networking demands of...
Existing solar energy harvesting systems are typically evaluated with a single configuration. However, results on different harvester configurations are often desired in order to select the appropriate match to specific ambient conditions and application requirements. In this paper, we therefore present a concept for remotely reconfigurable solar energy harvesting testbeds, which allows for multiple...
Vehicular communications are gaining one of the largest share of the automotive IoT market.

The Xhaul transport network is required to have the capability of carrying multiple traffic, such as CPRI and Ethernet,...
Industrial manufacturing is more and more based groups of robots in production cells. The robots consist of moving, bending and rotating arms with multiple joints. Cables that connect sections of robots undergo heavy stress from stretching and twisting, resulting in wear-out and failure. Replacing cables on robots by wireless communication therefore is an alternative that has been investigated for...
In this paper, we propose a resilient network and control co-design architecture, Wireless-Simplex (W-Simplex), which can guarantee control performance by adaptively tuning the network and control parameters against wireless channel uncertainty in cyber-physical systems (CPS). To the best of our knowledge, there has been no study on resilient network and control co-design in response to the unreliable...
