Unformatted text preview: joined a new foreign network. In this situation, the routing entries from the old foreign network might not have been completely withdrawn when the entries from the new network are being propagated. c) The time it takes for a router to learn a path to the mobile node depends on the number of hops between the router and the edge router of the foreign network for the node. ( This sub-question does not require submission of answer to Its Learning. ) Problem 7 (2.4) A frame without data is 32 bytes long. Assuming a transmission rate of 11 Mbps, the time to transmit a control frame (such as an RTS frame, a CTS frame, or an ACK frame) is (256 bits)/(11 Mbps) = 23 μ s. The time required to transmit the data frame is (8256 bits)/(11 Mbps) = 751 μ s. DIFS + RTS + SIFS + CTS + SIFS + FRAME + SIFS + ACK = DIFS + 3SIFS + (3*23 + 751) μ s = DIFS + 3SIFS + 820 μ s...
