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, the authors address the problem of establishing a vehicular network with high capacity using 802.11 and/or DSRC, and in particular they focus on frequency allocation and power control. They 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.
