Cоnsider the multiple аccess аlgоrithm CSMA/CA fоr the wireless 802.11 protocol. (а) (2 points) Explain what CSMA is and why it improves efficiency. (b) (2 points) Why is there no CD (collision detection) in 802.11? (c) (3 points) The CSMA/CA protocol results in the senders taking turns to transmit frames in a randomized fashion. Explain why that is the case. (d) (3 points) Consider two nodes with frames to transmit. Node 1 uses an earlier version of 802.11 with 10 Mbps transmission rate. Node 2 uses a newer version with 1 Gbps transmission rate. What is the resulting throughput under CSMA/CA? (e) (3 points) In addition to CSMA/CA, there is also the RTS/CTS option where a wireless station and the access point use the RTS/CTS messages to reserve time for exclusive use. How is the scheme different from TDMA?
