Performance of V2V Communication Distributed Resource Allocation Scheme in Dense Urban Scenario

In the 5G system, the distributed resource allocation scheme plays an important role for vehicle-to-vehicle(V2V) communication. However, in dense urban scenario, especially with traffic jam, there is big challenge for the distributed resource allocation scheme in V2V communication due to the limited wireless resources. In this paper, the success probability of V2V communication with distributed resource allocation scheme in the traffic jam scenario is analyzed based on the tool of stochastic geometry. Different interferences are analyzed in details and an important parameter, namely the energy detection threshold in the distributed resource allocation scheme is paid a particular attention to study its impact on performance. Theoretical results are verified by simulation and the results can provide useful insights to the parameter setting in different scenarios to achieve better transmission success probability.
