The traditional Contract Net Protocol model which works on Bids invitation between a Manager agent and Contractor agents can realize the collaborative task scheduling. But it also faces many problems such as the high network traffic and the low quality of task execution. Through analysis of the traditional contract net model, in this paper, the concept of role collaboration is put forward and introduced into the traditional contract net model and a new model of role collaboration contract net model is made. The theoretic analysis and experiments show that this new model can lighten the network, furthermore it can improve the efficiency of task scheduling.
