Security for 5G Wireless Communication Systems – Recent Development and Challenges
Wireless communication technologies are ubiquitous nowadays. Most of the smart devices have Cellular, Wi-Fi, Bluetooth connections. These technologies have been developed for many years, nonetheless they are still being enhanced. More development can be expected in the next 5 years, such as faster transmission data rate, more efficient spectrum usage, lower power consumption, etc. Similarly, cellular networks have been evolved for several generations. For example, GSM as part of 2G family, UMTS as part of the 3G family, and LTE as part of 4G family. In the next few years, 5G wireless communication systems will continue the evolution to keep up with the fast- growing needs of customers. Secure wireless communications will certainly be part of other advances in the industry such as multimedia streaming, data storage and sharing in clouds, mobile cloud computing services, etc. This tutorial covers the topics on security for next generation mobile wireless networks, with focusing on 4G (LTE and LTE-A) and 5G wireless communication systems, followed by a discussion on the challenges and open research issues in the area.

Network Science: An Introduction
This 1-day short course will offer an introduction to the emerging discipline of Network Science that has applications in computer networks and social networks, among others. Networks are characterized from a graph theoretic perspective which highlights their structural properties. The emphasis in the course is on quantifying the relationship between network topology and the expected performance of the network under a variety of conditions.
Contemporary networks appear to form somewhat randomly. This is especially the case for social networks, citation networks, the World Wide Web, and the Internet which provides the base structure for information networks. With increasing mobility, the nodes and transmission facilities are no longer static but continuously evolve in a fashion that appears random. How we can characterize such networks in a way that can lead to their protection or destruction (e.g., in the case of a biological network through which a communicable disease spreads) is an important objective of the course.
The course will define some of the most important parameters of such networks such as their nodal degree distribution, Betweenness and Closeness associated with a node, and the entropy of a network graph. Using these and other parameters, the properties of Random, Small-world, and Scale-free networks are analyzed. Emphasis is placed on the scale-free networks which characterize a vast number of evolving networks, including the Internet.

Modeling, Analysis, and Simulation of Multipath Radio Channels for Vehicular Communications
The interest that exists globally around the so-called intelligent transportation systems (ITS) has fostered a large amount of research activities aimed at developing new wireless communication technologies for the information exchange among vehicles on the move. The design of such technology gained an important momentum when in 1999 the American Federal Communications Commission (FCC) allocated a 75 MHz bandwidth in the 5.9 GHz band for dedicated short-range communications (DSRC) systems. A further step forward toward the development of vehicular communication systems (VCS) came recently in the form of an amendment to the IEEE 802.11 standard. This amendment, referred to as the IEEE 802.11p, provides specifications for the air interface of DSRC systems at the physical (PHY) and medium access control (MAC) layers. While the future ahead looks promising, the design of radio transceivers for VCS is not a trivial task, because the high speed at which the vehicles can move poses new challenges that are not a concern for conventional mobile communication systems. For example, due to the rapidly changing propagation conditions that are typically found in vehicular communication environments, the Doppler shift effects and the non- stationary characteristics of the wireless channel become exacerbated. These issues can significantly affect the performance of transceivers that are not optimized to operate over highly time-varying channels. Proper channel models are therefore needed that provide insights into the physics of vehicle- to-vehicle (V2V) and vehicle-to-infrastructure (V2I) radio reception, and at the same time, that lend themselves to mathematical and numerical system performance investigations. This tutorial seeks to provide a friendly introduction to the modeling, analysis and simulation of multipath radio channels for the performance evaluation of VCS. The tutorial is presented striving to make its contents accessible to the non-specialist, and enriching for professionals with experience in the field. Therefore, its target audience includes bachelor students, engineers, and researchers with interest in VCS.
