Joint optimization method of task offloading and resource allocation under uncertain wireless network
In an uncertain wireless network environment,the randomness of task arrival,user movement,and the time-var-ying nature of wireless channel states lead to uncertain network environment characteristics such as cloud queuing delay and device network connection time,which greatly affect the efficiency of computing offloading and network resource utilization.To address this issue,this paper establishes a dynamic task offloading and edge resource adaptive allocation model for com-puting and network coordination.A multi-stage stochastic programming optimization algorithm(SS-MSSP)for task offload-ing and joint resource allocation based on stochastic simulation was proposed with the goal of minimizing the total energy consumption of the system.The multi-stage stochastic programming theory was used to formulate multi-stage strategies,and the posteriori computing network resource allocation method was used to compensate for the impact of uncertain network en-vironments.Simulation results show that in an uncertain network environment,the SS-MSSP algorithm ensures the user's computing delay requirements while effectively reducing system energy consumption.
