Abstract:The surge of concepts of the connected world, IoT, IoV, smart cities and many more, drive academic and industrial research activities from various relevant domains towards a unified direction. Generally labeled as heterogeneous networking, hosting different technologies, interoperating with each other, to fulfill demands of a wide range of innovative applications. Intelligent Transportation Systems (ITS) in the domain of vehicular networking, as an integral part of such a smart ecosystem, are subject to rapid developments. Data broadcast, as the main communication type in vehicular networks, is of significant interest of research community. IEEE 802.11p/1609 is known as the standard communication protocol suit for vehicular networks. However, it does not have any MAC-layer acknowledgment scheme for broadcast communication. Considering the lack of this feature, challenges arise to provide reliable communication and keep the performance of such systems and applications reasonable. Many works have been proposed in the literature to improve reliability of vehicular broadcast. However, it has not been possible so far to provide ultra-reliable broadcast communication in vehicular networks and it is important for many applications, including safety-critical applications. In this regard, 5G, as the next generation of the mobile networking system, is a promising solution to be utilized for improving vehicular communications. 5G will not be just an enhancement of the current fourth generation of mobile networks, LTE/LTEA, but rather an end-to-end system, realizing a fully mobile and connected society. Such a system will enable diverse use cases with extreme range of requirements, which can be reflected in the proposed architecture. Transportation is one of the main verticals in the focus of 5G. Taking into account this vertical, two main points are directly related to vehicular communication, Device-to-Device (D2D) and Machine Type Communication (MTC). These two emerging technologies of wireless cellular systems, are in the core of the 5G system. D2D refers to the direct communication between vehicular users without the interaction of any base station. This is mainly used for broadcasting messages among the vehicular devices.Resource management is fundamental aspect of D2D communication as it affects directly its performance. It can improve the system efficiency by making more suitable allocations depending the scenarios on which the message broadcasts are done. In this work, we study two types of resource allocation methods for LTE D2D and analyze their performance difference. We mainly focus on resource efficiency and delivery success rate.
