Estimate the efficiency of CSMA assuming that maximum propagation delay is 240ns, transmission rate of the shared link is 15Mbps and maximum frame size is 2KB. How much should we increase the transmission rate of the shared link so that slotted ALOHA can compete with CSMA and have the same efficiency.

Q6. Total: 7 marks] Nodes A and B are accessing a shared medium with propagation delay of 300 bit times between them (i.e., propagation delay equals to the amount of time to transmit 300 bits onto the link). A and B each have a frame of 1,000 bits (including all headers and preambles) to send to each other. a) (3 marks] In the worst case, how many bits would A have sent out when it detects collision?

03) Consider sending a file size of O bits over a path of 2 links. Suppose the first link can transmit at R1 bit/sec (bps) and the second link can transmit R2 bits/sec (bps) (R1+ R2), both links have a propagation delay of tp, network lightly loaded (no queuing delays), and each link's maximum frame size, S bits, is same (S < O and number of segments is integer and headers are negligible.).

Suppose within your Web browser you click on a link to obtain a Web page. The content of the web page is not cached in the local caching server, and the IP address for the associated URL is not cached in your local host either, so that a DNS look-up is necessary to obtain the IP address. Suppose that n DNS servers need to be visited before your host receives the IP address from DNS, and each of successive visits...

In this problem you will estimate the heat lost by a typical house, assuming that the temperature inside is T(in) = 20 degrees celcius and the temperature outside is T(out) = 0 degrees celcius
In this problem you will estimate the heat lost by a typical house, assuming that the temperature inside is T(in) = 20 degrees celcius and the temperature outside is T(out) = 0 degrees celcius. The walls have fiberglass insulation, which dominates the heat conduction properties of the wall So we can consider the wall to have a thermal conductivity of k(wall) = 0.048 W/m/K . We will take the thickness of the walls and ceiling to be L(wall) = 12...

2. ๒ class we have discussed the general concept of impedance matching to achieve maximum efficiency of the transfer of energy from one medium or system into another. For example, in an electrical systom where a source of electrical power is transferring energy to a load, you have leaned that maximum power impedances are matched, Le. where the real parts (resistance) are equal, and the reactance cancels. One of the many physiological systems in which impodance matiching is important is...
