Abstract:
                                      Aim at improve the adaptive capacity of node failure and task difference, a multi-functional distributed system node collaboration method based on time resources management is proposed. Firstly, the collaboration method is formulated by the integration of unified node grouping, complete task information loading, consistent parameter setting and orderly function switch time sequence. Then, taking example of environment comprehensive awareness, a multi-functional distributed system function switch model and an optimization algorithm is proposed, respectively. Finally, the effectiveness of the proposed method is verified by simulation.
