so we need to respond to user with the entire route? just making sure as in project sheet "the number, and departure time of the next bus or train leaving the source station that enables the passenger to reach the required destination station, and t...

when starting station program via . station ... Why is shown to be the final argument given in examples?

Hey, just wanted to clarify the inputs user makes to get desired output, as well as what the desired output specifically is. User Input destination station name current time - does user input a time when they leave, or will program just get the cur...

What I meant is that the parameter is the probability that a node has a new frame for transmission , if a specific node is already trying to retransmit, do we ignore any new frames for that node. As in context, I believe a node may be able to get a n...

In the slotted aloha, if a node is looking to retransmit message, does it not consider any new messages it may have to send while trying to retransmit? More specifically, each node has chance to transmit a new message, if a node is trying to retransmi...
