Abstract: Task allocation modeling plays an important role in UUV collaborative system. In order to solve task allocation problem for the collaborative capability and efficiency, the Extended Contract Net Protocol (ECNP) task allocation approach was creatively proposed, which mainly focused on narrow the scope of communication and improving the negotiation efficiency. In this approach, Regional Trust Degree was introduced to narrow the scope in Announcement stage; and the capacity constraints (Energy-state, Health-State, and Detecting-window) were employed to decide whether to participate in bidding stage; also mixed-weighting evaluation strategy based on Game theory was proposed to evaluate the biding in Awarding stage. The typical experiment was designed to verify the proposed approach. Simulation results show the proposed model has good performance for Agent-oriented UUV collaborative system.
