基于5G车联网城市二维覆盖的低功耗路边单元部署策略
Low-power-consumption road side unit deployment strategy for urban 2-D 5G Internet of vehicles
摘要
Abstract
In urban Internet of vehicles(IoV)systems,the road side unit(RSU)was commonly deployed at road intersec-tions to provide two-dimensional service coverage.However,due to vehicle dynamics,RSU might suffer from massive power waste.A novel RSU deployment strategy was proposed that dynamically adjusted the operating mode and trans-mission power of RSU,based on the spatial distribution of vehicles.An adaptive mapping mechanism between RSU power consumption and vehicle distribution patterns was established that overcame the power consumption bottleneck caused by traditional RSU's fixed coverage to minimize the total power consumption of RSU.Furthermore,the concept of candidate communication service area(CCSA)was introduced,utilized in combination with an exploratory RSU de-ployment algorithm(ERDA)and an enhanced genetic algorithm(eGA)to implement the RSU deployment strategy.Analysis and simulation results indicate that,compared with conventional methods,the proposed RSU deployment stra-tegy significantly reduces redundant road coverage,leading to minimized RSU power consumption.In low vehicle den-sity,the ERDA can achieve optimal solutions with low computational complexity.In high vehicle density,the eGA pro-vides a reasonable balance between complexity and performance.Therefore,the proposed strategy provides practical en-gineering guidance for urban transportation systems.关键词
