Background CSMACD stands for carrier Sense, Multiple Access, and Collision Detection. We use a simplified version where the protocol:  If a station is ready to send a message (according to a random number R1) it senses the carrier. The station can only sense the part of the carrier that is directly attached to the station. a. If the carrier is free the station start transmission of a random message (length R2 ticks) Otherwise, the station delays sensing the carrier by a random (R3) number of ticks. If a station detects collision it stops the current transmission and delays sensing the carrier by a random number of ticks (R4) As long as a station is attempting to send a message it does not generate new messages. The number and location of stations on the carrier, the carrier length in meters (R5), and the propagation time of a message through the carrier in tics/meter are given.  We assume that a tic is a time that it takes for a message to propagate a distance of one meter in ...
