Mobility-Aware Optimal Task Offloading in Distributed Edge Computing

To cope with limited capabilities of mobile devices, task offloading in distributed edge computing (DEC) environments is perceived as a promising solution. However, the mobility of devices makes the task offloading a more challenging issue. In this paper, we investigate mobility-awareness for optimal task offloading in DEC environments. To this end, we formulate an optimization problem to minimize the response time of offloaded tasks. Simulation results demonstrate that the mobilitya ware task offloading scheme can reduce the response time by 14% similar to 21% compared with the conventional task offloading schemes without any mobility-awareness.
