​10:05 Keynote: An Introduction to Stochastic Geometry and its Applications in Vehicular Networking
Current and future wireless systems, including cellular, cognitive, ad hoc, D2D, M2M, and vehicular networks, are characterized by irregular and unpredictable locations of users and infrastructure. As a result, these networks are best modeled using stochastic point processes, which permits the application of the powerful tools of stochastic geometry for the network performance analysis. In the first part of this talk, we give a brief introduction to stochastic geometry, including the main models and the key results that enable the calculation of interference and SIR distributions. In the second part, we focus on applications specific to vehicular networks. We discuss models for traffic in single- and multi-lane highways, possible channel access schemes, and we present some examples of problems that can be addressed theoretically using stochastic geometry.

13:00 Using Stochastic Geometry to Model Packet Reception Probabilities in Vehicular Networks
Future intelligent transportation systems, where vehicular communication systems play a key role, are envisioned to alleviate many of the problems related to safety and efficiency in the current road transport system. However, before vehicular communication systems can be used in safety critical applications we need to quantify the performance in different scenarios. Measurements campaigns and simulations to evaluate the reliability of packet transmission are slow and scenario-specific. Thus it is desirable to complement these with analytical key performance metrics that can give quick insights about performance and scalability. In this talk I will give an overview of how tools from stochastic geometry can be used to analyze the impact of interference in vehicular network, and to analytically characterize the packet reception probability in an intersection scenario.

13:30 On the Performance of Amplifier-Aware Dense Networks: Finite Block-Length Analysis
We investigate the performance of dense Poisson-point-process-based cellular networks using finite length codewords. Taking the properties of the power amplifiers (PAs) into account, we derive the outage probability, the per-user throughput and the area spectral efficiency in different conditions. Our analysis is based on some recent results on the achievable rates of finite-length codes and we investigate the effect of the codeword length/PAs properties on the system performance. Our numerical and analytical results indicate that the inefficiency of the PAs affects the performance of dense networks substantially. Also, for a given number of information nats per codeword, there is an optimal finite codeword length maximizing the throughput.

14:00 Coverage Analysis and Blockage Effects in Cellular Networks
Cellular networks in a dense urban environment are prone to blockages. The blockage effects can result in a significant difference in received power between line-of-sight (LOS) and non-line-of-sight (NLOS) links, especially for millimeter-wave communications. In this talk, we study the coverage probability of a network where transmitters are distributed according to a Poisson point process. We distinguish between LOS and NLOS links using a distance-dependent LOS probability function, and give the coverage performance for a partial-zero-forcing receiver (PZF). The results demonstrate the decrease of interference due to blockages and the coverage improvement using PZF.

15:00 Urban Traffic Control for Future Intelligent Transportation Systems
Traffic congestion is an important cause of pollution and economic loss. If unchecked, these problems are expected to increase, especially in dense cities. Urban traffic control and coordination can address this challenge and improve efficiency, fuel consumption, and safety. In this talk, after a brief digression into microscopic traffic control, the problem of controlling traffic lights under fixed and adaptive routing of vehicles in urban road networks is considered. Based on multi-commodity back-pressure, originally developed for routing and scheduling in communication networks, we develop algorithms to road networks to control traffic lights and adaptively reroute vehicles in a decentralized manner.

15:30 Moving Networks
The usage of broadband services via mobile devices is becoming increasingly important. With 5G, users will expect the connected society to be available with no limitations, and users will make use of bandwidth-demanding services like augmented reality and virtual office applications, also when on the move. In this context, future vehicles and transportation systems may play an important role in wireless networks by providing additional communications capabilities and becoming an integrated part of the communications infrastructure to improve capacity and coverage of the operator driven mobile networks. That is, in order to serve vehicular users effectively, one promising solution is to deploy moving base stations on the vehicles to form moving networks (MNs). Such moving network nodes can also be used to realize reliable communication links between vehicles and mobile devices of other traffic participants in order to enable new V2X services based on cellular communications, which has the potential to improve traffic safety and efficiency. We show that by using MNs, the quality of service for the vehicular users can be significantly improved with no obvious impact on the performance of regular outdoor users. We also present a promising enabling technology to boost the spectral efficiency of the moving base station backhaul link and to fully integrate moving base stations in cooperative heterogeneous networks - the predictor antenna concept.

16:00 V2V Communications Reliability over Urban Intersections
According to the UN’s World Health Organization over 1.25 Million road-traffic deaths occur every year. In Europe, road safety is much better, yet it is staggering to realize that roughly 230 road-traffic deaths arise every single day. Moreover, it is worth remarking that nearly half of these fatalities occur at a street intersection due to careless driving, speeding, drink-driving, etc. Meanwhile, on the technological side, it is reassuring to recognize that next generation wireless systems have given a lot of attention to the paradigm of vehicle-to-vehicle (V2V) communications, particularly for the purpose of road-safety. Indeed, support for V2V services is already part of LTE Rel-14, and this momentum will further continue on as we gradually migrate to 5G networks near 2020. For delay-sensitive road-safety purposes, a network packet reliability of 10^-5 is envisioned in the 5G ecosystem. At the system-level, this reliability rate is higher, yet still the requirement remains quite challenging to fulfill. As a mean to evaluate this 5G condition at the PHY/MAC layers, it is of utmost importance to transform the V2V communication challenge into carefully crafted analytical models in order to identify the contribution of the related variables as an aiding tool in the design of the V2V communication system. In this talk, we will discuss some of our preliminary research on V2V Communications around an urban intersection under extreme NLOS scenarios based on empirically supported channel models. Our analysis takes into account various critical elements including: propagation for urban/suburban intersections; random/deterministic traffic flows; finite/infinite interferers; lane/vehicle dimensions; etc.
