“…In [4], vehicles make use of the position information transmitted by other vehicles, in order to choose the resources for V2V transmissions without any network supervision. In [5], the resource pools are created in a time-orthogonal manner, with respect to orthogonal road traffic crossing the intersections. Further, vehicles perform sensingbased resource selection inside each pool.…”

“…For this, we consider two cases: 1) all vehicles travel with a constant speed of 30 m/s; and 2) vehicles have random constant speeds uniformly distributed between 20 and 30 m/s. For the first case, we evaluate the performance of the scheduler when the vehicles are predicted to have the same constant speed of 5,15,30,35 and 45 m/s, as well as random constant speeds uniformly distributed between 5-15, 15-25, 25-35, 35-45 and 45-55 m/s. For the second case, we evaluate the effect of vehicles being predicted to have the same constant speed of 5,15,25,35 and 45 m/s, together with the predictions of random constant speeds distributed uniformly between 5-15, 20-30, 25-35, 35-45 and 45-55 m/s.…”

We explore a new approach to radio resource allocation for vehicle-to-vehicle (V2V) communications in case of outof-coverage areas that are delimited by network infrastructure. By collecting and predicting information such as vehicle velocity, density and message traffic, the network infrastructure ensures reliability of the V2V services. We propose reserving required amount of resources for services that cannot be pre-scheduled (e.g., emergency braking, crash notifications, etc.), and scheduling those services that can be pre-scheduled (e.g., platooning). We analyze the resource reservation as a function of target reliability under varying vehicle densities and sizes of out-of-coverage area. For pre-scheduled services, we explore how variations in the vehicle velocities and predictions affect successful transmissions.The results indicate that increase in required reliability does not penalize the system prohibitively. On the other hand, speed prediction errors decrease the transmission success rate considerably, thus calling for a more flexible scheduler design.

“…In [47], a two-stage distributed resource selection for V2V communication in urban scenarios was proposed. In the first stage, resources are partitioned based on vehicles heading direction, i.e., the cars moving in the same direction have same set of resources (a resource pool) to select and there will be no collision in junctions due to the different mobility direction of cars.…”

Long-Term Evolution (LTE) is a promising technology to be applied for different applications due to its high penetration, high data rate, reliability, and QoS support. One of the emerging applications for LTE is vehicular networks. Vehicular networks can raise traffic safety, improve traffic management, or provide infotainment services for road users. LTE device-to-device (LTE-D2D) communication which was proposed by 3GPP working group is also a good candidate to be applied for vehicleto-vehicle communications (V2V). The V2V communication for traffic safety has strict QoS requirements in terms of latency and reliability. LTE-D2D may provide high reliability and low latency for such a communication. However, an efficient radio resource management for V2V communications in an LTE network is required to support such requirements. In the current article, we introduce vehicular networks, their requirements, and existing technologies to be employed in them and specially look at LTE-D2D to connect cars. Most recent works in radio resource management for V2V communications in LTE are reviewed in this work.

“…Distributed scheduling with autonomous resource selection is more scalable and can work when eNodeB cover is not available. Performance gains with collision avoidance (CA) and location based resource allocation enhancements were reported for autonomous resource selection in [4], [10]. However, these enhancements have many design options and parameter settings, the impact of which have not been well studied in the literature [4], [5], [9], [10].…”

In this paper we investigate the distributed autonomous resource selection for LTE vehicle to vehicle (V2V) broadcast. The effectiveness of collision avoidance and location based resource allocation enhancements is examined. It is found that collision avoidance with multiple data resources reservation per schedule assignment (SA) is a key to improve broadcast reliability. However in the existing collision avoidance algorithm reserving multiple resources per SA can lead to many data packet collisions if a SA collision happens. We propose an enhanced collision avoidance to address this issue. The idea is to use selected data packets to disseminate the reservation of data resources and SA resources, which can provide better communication among neighbor vehicles on resource reservation and reduce data collisions. Simulation results show that the proposed collision avoidance enhancement can effectively improve SA and data transmission reliability. The network capacity in terms of supported vehicles under given V2V service requirements is largely increased by 17% at a negligible cost of added overhead.
