Abstract: Coordination of agent is the guarantee for the?multi-agent system playing the overall efficiency and also is a core problem of agent system. The contract net model is the classical coordination strategy in multi-agent system, but it still has some defect. This paper mainly improves the biding strategy of contract net and advances a task allocation strategy with precision. This paper uses the precision to evaluate the bid values of agent, and makes it more close to the real value. This paper also makes a detail evaluate for capability and load of the former synthetic evaluation task allocation strategy. After analyzing the agent capability in detail, it classifies the quality and cost to an evaluation?of agent capability. But the improvement of load adds the evaluation of task number in the task list. Finally, this paper carries out the simulation experiment for the improved method based on wireless sensor networks in the end.
