Wireless LAN standard IEEE 802.11 has evolved throughout the last two and half decades. The security measures, Physical layer and MAC layers have been modified as per the need of the hour. 1.a) What are the MAC layer improvisation took place in the context of hidden node terminal and exposed node terminal since the first standard appeared, explain the problem with appropriate figures. (500 words minimum, add atleast two diagram) 1.b) Mention at least four latest issues which it (IEEE 802.11) needs to deal with while being incorporated with Internet of Things (IoT). 1.c) Describe CSMA/CA and CSMA/CD? Why CSMA/CD was not preferred over CSMA/CA for WLAN? Please adhere to the following guidelines for writing your summary: Your report should include at least two figures and/or tables. Do not forget to include a caption for each figure/table and to use cross-referencing. Ensure that your report meets the objectives, has an appropriate structure and style, and that its technical level is appropriate for the audience, purpose and medium. For more details, you can refer to the T215 textbooks (Block 1 – Part 7; Block 2 – Part 7 and Block 3). You MUST include at least 5 good quality references and ensure that they are cited within the text of your solutions making use of citing/referencing style you have learned in session 6 of T215A.
