Abstract

In order to improve the efficiency of task offloading in Ad hoc cloud, aiming at the effect of node random movement and resource heterogeneity on task offloading, this paper proposed a multi-criteria task offloading algorithm based on mobility prediction, which was used to predict node escaping time based on time series analysis and as a measure of mobility. It got the weights of CPU speed, number of cores, workload and mobility by using the analytic hierarchy process. The task was offloaded according to task size and the combined weights which had been calculated. The simulation results show that the proposed algorithm can reduce the task execution time and energy consumption effectively compared with the random task assignment algorithm and Min-Min scheduling algorithm.
