For transmitting the data which is composed of sensed information in sensors, wireless sensor networks have been developed and researched for the improvement of energy efficiency, hence, many MAC protocols in WSN employ the duty cycle mechanism. Since the progressed development of the low power transceiver and processor let the high energy efficiency come true, the delivery of the multimedia data which occurs in the area of sensor work should be needed to provide supplemental information. In this paper, we design a new scheme for massive transmission of large multimedia data where the duty cycle is used in contention based MAC protocol, for WMSN. The proposed scheme can be applied into the previous duty cycle mechanism because it provides two operations between normal operation and massive transmission operation. Measuring the status of the buffer in a sender and the condition of current radio channel can be criteria for the decision of the above two operations. This paper shows the results of the experiment by performing the simulation. The target protocol of the experiment is X-MAC which is contention-based MAC protocol for WSN. Two approaches, both X-MAC which operates only duty cycle mechanism and X-MAC(MTS) which operates combined massive transmission scheme, are used for the comparative.
