In this paper, we deal with suggestion of energy efficient MAC protocol. The scheme(I-MAC) makes the active duty-cycle duration based on by utilizing data frequency. Data frequency is made by checking a check bit of Link layer. By being studies on NS-2 simulation environments, the proposed scheme was proved to be improved in terms of energy efficiency of 50 % and to be similar to throughput of S-MAC on every time interval.
