Packet-switched roadside base station to vehicle communication for intelligent vehicle/highway systems

چکیده
Abstruct: Optimum frequency reuse patterns for roadside base station to vehicle communications in Intelligent VehicldHighway Systems (IVHS) are determined based on optimal delayhhroughput and packet erasure rates for BPSK transmission over narrowband dispersive Rician channel with IS1 and (Rayleigh-faded) co-channel interference. For fixed cluster size and fixed total system bandwidth, a reuse pattern of 2 for continuously transmitting (hence interfering) base stations gives minimum average delay and maximum spectrum efficiency: this is a denser pattern than suggested for highway cellular telephony networks. Spectrum efficiency is enhanced by using a dynamic cluster size which depends on the distance from the base station, taking advantage of the IVHS environment where vehicle position may be known.

متن کاملEffects of Vehicle-vehicle/ roadside-vehicle Communication on Adaptive Cruise Controlled Highway Systems
In this paper we study the effect of vehiclevehicle/vehicle-roadside communication on the performance of adaptive cruise control (ACC) systems. Two simulation works are presented. One is a single ACC vehicle simulation using MATLAB/SIMULINK. A cut-in scenario and a braking scenario are tested. Communication greatly saves control effort in the former scenario, while has little effect in the latt...
