Cooperative intelligent traffic systems (C-ITS) will help improve the safety and efficiency of ground transportation by enabling the cooperation between traffic participants. Applications based on the C-ITS paradigm rely on vehicle-to-vehicle, vehicle-to-infrastructure, and vehicle-to-device (collectively, V2X) communication for the exchange of critical information and have very stringent Quality...
Mobile networks are experiencing the avalanche of data traffic, which is coupled with the billions of wirelessly connected data-intensive devices using diverse multimedia services and applications. Prospective studies suggest that traffic volume would increase a thousand-fold over the next decade. Furthermore, the users expect the utmost in quality with seamless connectivity to the broadband access...
This paper presents an optimization framework for energy savings in nomadic relay networks, where interference and load are changing over time due to varying assignments. We prove the existence of an explicit load function taking assignments as arguments and we show the function is continuously differentiable. Based on the properties of the load function, we design iterative relay and user association...
Next generation mobile and wireless communication systems beyond 2020, aka Fifth Generation (5G) systems, aim at providing ubiquitous user experience with the utmost in quality. One of the promising technologies targeted for 5G systems is the flexible network deployment based on nomadic nodes (NNs). An NN is a low-power movable access node that provides coverage extension and capacity improvement...
Device-to-device (D2D) communication as an underlay to future cellular networks has been recently considered as an efficient cell offloading and capacity increasing solution. In this paper, we propose to use the D2D underlay as a carrier for automotive safety applications with very strict quality of service and reliability requirements. We propose a location dependent resource allocation scheme (LDRAS)...
