Radio Resource Allocation for a High Capacity Vehicular Access Network

Vehicular networks will enable a high number of services in intelligent transportation systems, and are also expected to improve the availability of wireless services to vehicles. In this paper we address the problem of establishing a vehicular network with high capacity using 802.11 and/or DSRC, and in particular we focus on frequency allocation and power control. We advocate a regular frequency reuse pattern that guarantees SINR requirements of the air interface. Resulting co-channel interference is then reduced using an adaptive power control algorithm. Simulation results for a highway scenario reveal that high capacities are possible with moderate infrastructure access point density.
