Abstract: A joint prediction and edge computing framework for haptic communications is constructed. The tradeoff between delay and energy consumption is clarified, and the prediction benefit of the transmitter is defined. In order to maximize the sum prediction benefit, a joint optimization problem of multi-transmitter prediction window and computing offloading strategy is constructed. Then, the optimization problem is transformed into a multi-transmitter prediction and computing offloading game, and a joint optimization algorithm of prediction and computing offloading based on best response is proposed to converge to the Nash equilibrium. Simulation results show that the proposed algorithm can achieve near-optimal performance.
