An Optimization Scheme for Task Offloading and Resource Allocation in Vehicle Edge Networks

Abstract

The vehicle edge network (VEN) has become a new research hotspot in the Internet of Things (IOT). However, many new delays are generated during the vehicle offloading the task to the edge server, which will greatly reduce the quality of service (QOS) provided by the vehicle edge network. To solve this problem, this paper proposes an evolutionary algorithm-based (EA) task offloading and resource allocation scheme. First, the delay of offloading task to the edge server is generally defined, then the mathematical model of problem is given. Finally, the objective function is optimized by evolutionary algorithm, and the optimal solution is obtained by iteration and averaging. To verify the performance of this method, contrast experiments are conducted. The experimental results show that our purposed method reduces delay and improves QOS, which is superior to other schemes.
