Abstract: 

The transmission capacity of vehicular relay assisted networks coexisting with cellular networks is studied in this paper. The transmission capacity was analysed in both underlay and overlay cases. Vehicle-to-Vehicle networks, cellular users and relay nodes (RNs) are all modelled using poison point process based on stochastic geometry. Then the probability of RN existence and the relay link distance expectation for obtaining the successful transmission probabilities for V2V is calculated. Further, the transmission capacity of V2V communication with relay nodes in both underlay and overlay modes were obtained. Finally, simulation results show that V2V transmission capacity is improved by using relay transmission and influenced by various factors like V2V density, cellular user density, power, V2V link distance, but also the way of using RNs in V2V communications.
