This paper provides an overview of the Internet of Things (IoT) with emphasis on enabling technologies, protocols and application issues. The IoT is enabled by the latest developments in RFID, smart sensors, communication technologies and Internet protocols. The basic premise is to have smart sensors collaborate directly without human involvement to deliver(More)
Security is critical for sensor networks used in military, homeland security and other hostile environments. Previous research on sensor network security mainly considers homogeneous sensor networks. Research has shown that homogeneous ad hoc networks have poor performance and scalability. Furthermore, many security schemes designed for homogeneous sensor(More)
Several routing protocols have been proposed in recent years for possible deployment of Mobile Ad hoc Networks (MANETs) in military, government and commercial applications. In this paper, we review these protocols with a particular focus on security aspects. The protocols differ in terms of routing methodologies and the information used to make routing(More)
ULTRA-WIDEBAND (UWB) transmission has recently received increased attention in both academia and industry for multimedia applications in short-range wireless communications. It has many advantages such as high data rate, availability of low-cost transceivers, low transmit power, and low interference. UWB operates at emission levels commensurate with common(More)
In this article we propose a cross-layer approach to investigate the impact of the physical-layer infrastructure on the data-link-layer QoS performance in mobile wireless networks. At the physical layer, we take the MIMO diversity schemes as well as AMC into account. At the data-link layer, our focus is on how this physicallayer infrastructure influences(More)
Cognitive Radio (CR) is a novel technology that promises to solve the spectrum shortage problem by allowing secondary users to coexist with primary users without causing interference to their communication. Although the operational aspects of CR are being explored vigorously, its security aspects have gained little attention. In this paper, a brief overview(More)
5G networks are expected to achieve gigabit-level throughput in future cellular networks. However, it is a great challenge to treat 5G wireless backhaul traffic in an effective way. In this article, we analyze the wireless backhaul traffic in two typical network architectures adopting small cell and millimeter wave communication technologies. Furthermore,(More)
The current centrally controlled power grid is undergoing a drastic change in order to deal with increasingly diversified challenges, including environment and infrastructure. The next-generation power grid, known as the smart grid, will be realized with proactive usage of state-of-the-art technologies in the areas of sensing, communications, control,(More)
