Aloha network
Given an ALOHA network: - Speed of the channel is 10Mbit/s. Channel length is 500m. Speed of signal in the channel is 2*10^8 m/s. - There're 30 computers connected to this network - The average speed of data flow from the application ... with the length of each packet is 100bit and 1000bit. Discus about the relationship between packet length, channel length and throughput S max?

#Self Doubt
When we say that vulnerable time in pure aloha will be 2*frame transmission time.So what this frame transmission time?? My doubt is does frame transmission time= propagation time+transmission time … collision can also happen during propagation time ??

Consider 2 stations at a distance of 1 km from each other (Aloha)
Consider 2 stations at a distance of 1 km from each other. A station transmits frames of length 100 bits at the rate of 1 Mbps. Velocity of propagation is 2 * 108 m/s. Assume that each station generates frames at an average rate of 10000 frames per second. What is the probability of collision for pure ALOHA and slotted ALOHA ?
