2. Consider the wireless topology of 6 nodes given in Figure below. Circles around each node illustrate their transmission range. Assume that the transmissions of two nodes collide if and only if they transmit at the same time in overlapping transmission areas. Further, assume that losses occur only due to collisions. A B D (a) When node A transmits to node B, list the potential hidden and exposed terminals. (b) What about when node B transmits to node C? (c) Taking help from above cases, explain how (RTS/CTS) can solve the problem of hidden and exposed terminals. (d) RTS/CTS is more like time-division multiplexing or frequency-division multiplexing?
