Consider two nodes (A, B) sharing the same broadcast channel of speed R =10Mbps. The propagation delay between the two nodes is 1ms. Consider a node C in the middle between both nodes. If A starts at time t=0 its transmission of a packet to node C, at what time can node B start transmitting its packet to a node D in the network in order for the two packets not to collide? Assume both nodes have each a packet of length L = 1000Bytes. O a. 1.3ms O b. 1ms O c. 0.5ms O d. 1.8ms
Suppose three active nodes (n1, n2, and n3) are competing for access to a channel using slotted ALOHA. The channel is capable of transmitting a given frame at the full channel rate of R Mbps (R = 27Mbps). Assume each node has an infinite number of packets to send, and attempts to transmit in each slot with a probability p. The maximum network throughput is: a. 10Mbps O b. 12Mbps C. None of the above O d 4Mbps
