Talk Title: Delay-Aware D2D Networking
Abstract: Taking advantage of the physical proximity of communication devices, D2D techniques enable direct communications between devices without passing through the base station and this results in high data rates and low power consumptions. In this talk, we give a brief overview of the motivation and technical challenges of supporting delay-aware D2D systems. We also present a case study where we derive a low complexity closed form power control solutions for delay-aware D2D networking. Extensions and generalization of the techniques will also be addressed.

Talk Title: Communications when most needed: Wireless in Emergency and Disaster Situations
Abstract: The role of wireless communication in emergency, safety, security, and rescue operations is very crucial. One of the major challenges in today’s wireless world is the ability to deploy a secure and reliable communications network in disaster and emergency scenarios. Past experiences (September 11, Hurricane Katrina, and many others) have shown that today’s commercial wireless communication networks fail when they are most needed. It is well documented that the wireless systems became overloaded, as certain infrastructure was destroyed and other infrastructures were overwhelmed. During these events it was clearly seen that the ability to exploit a multitude of communication networks, both private and public, the interoperability between the available networks, the flexibility of the wireless devices to operate across different networks with adaptive radio capabilities, the capability of the networks to operate in both centralized and distributed manner are some of the important issues that the wireless communications community still has long way to go. In this presentation, we will discuss the role of wireless communications in safety, security, and rescue, and discuss some of the challenges for these applications.

Talk Title: What is in it for D2D in 5G wireless and Support of Underlay Low-Rate M2M links?
Abstract: The research work on 5G wireless systems is gaining momentum and, in that context, Device-to-Device (D2D) communication has the potential to introduce new applications and use cases, beyond the current focus on D2D in relation to public safety. In the first part of the talk, D2D communication will be discussed in terms of its uses and challenges within the 5G scenarios pursued in METIS, a large European research effort on 5G wireless technologies. Those uses of D2D include, for example, machine-to-machine (M2M) communication in smart grids and vehicular environments. The second part of the talk will explore the opportunity opened by D2D links for supporting underlay low-rate M2M links. Specifically, we consider an on-body M2M device connected to a mobile phone that acts as a relay towards the Base Station (BS). The low-rate requirement for this D2D connection allows underlay operation with Successive Interference Cancellation (SIC) during the cellular downlink transmissions. We investigate the tradeoff between, on one hand, the achieved rate for the downlink cellular users and, on the other hand, the outage probability for the MTC link. The results show that SIC is an important enabler of low-power underlay D2D transmission for low-rate machine-type traffic.
