Abstract: This paper makes an improvement on the implementation of exiting Complex Event Processing(CEP) engine according to the present advantage and disadvantage. Considering some key points including Ad hoc query and Time-Window, it adopts pre-processing and dispatch module. It implements an improvement edition(SPSA) of STEAM system. Experimental results prove that the solution above is constructive. It can improve the efficiency of the engine and decrease the pressure of the system under some condition.

Key words: Complex Event Processing(CEP), stream processing, Ad hoc query, Time-Window
