基于信息安全强度的路侧设备任务调度优化策略
Task scheduling optimization strategy for roadside unit based on security strength
摘要
Abstract
In the context of cooperative vehicle-infrastructure systems(CVIS),vehicles often offload computational tasks to roadside units(RSUs)for execution due to their own constrained computing resources.A novel approach that has garnered increased attention involves the"vehicle-edge-cloud"framework,wherein RSUs decide whether to process tasks locally or to offload them to the cloud.The open and unpredictable nature of the wireless channels on the"edge-cloud"interface necessitates the incorporation of a security mechanism to safeguard the integrity of information transmission.However,integrating such a security mechanism can escalate the energy consumption of RSUs.Addressing the challenge of jointly optimizing roadside energy consumption and information security utility,without compromising task delay constraints,is a complex issue.To tackle this,an energy-packets queue tradeoff of task scheme and encryption strategy(EPTS)was introduced.This approach involved the development of a vehicle speed state model,a task encryption model,a data cache queue model,and a task calculation model,along with the formulation of an optimization objective function.The optimization model was subsequently transformed using Lyapunov optimization theory and was reformulated as a knapsack problem for resolution.The simulation results confirm the EPTS's commendable convergence and effectiveness.The average objective value achieved by the proposed EPTS was found to be 17%superior to that of the Equal Allocation Strategy(EAS)and 21%superior to the queue-weighted strategy(QS).关键词
