Wireless protocol simulation using event-driven

Hi... I will create a simple simulator to evaluate the performance of the network using basic bit mapped protocol. Assume there is N devices, and each device will generate a data frame at the beginning of each slot with a probability P (0<1<P). If a device already has a frame waiting for transmission or is transmitting a frame, a newly-generated frame will be dropped by the same device. It is assuming that a frame will need 10 slots for transmission. Can anyone help me to figure it out using event driven method?
