    Wireless sensor network shows variety of applications in different real world scenarios because of their self organizing capabilities and their abilities to respond over varying environmental conditions. With the advance of efficient sensor nodes, the application areas have been increased considerably during the recent time. A wireless sensor network mostly uses SMAC as medium access control. The main features of SMAC protocol are periodic listen and sleep, collision avoidance, overhearing avoidance, and message passing. The S-MAC can reduce the energy consumption considerably by using theses energy-saving features. However, it generates the higher delay time of the data. We propose cross-layer designed sensor MAC protocol (CL-SMAC) for delay-sensitive applications. The basic idea of CL-SMAC remains same as SMAC with the modification in periodic listen and sleep. CL-SMAC has more opportunities to transfer data by adjusting the transmission duty cycle. Simulation results show that the average latency for CL-SMAC can be reduced according to the sensed data at the deay-sensitive application.
