Here is the research paper that originally proposed MACAW (Medium Access for Collision Avoidance for Wireless) protocol: https://pdos.csail.mit.edu/archive/decouto/papers/bharghavan94.pdfLinks to an external site. An informal discussion can also be found in Wikipedia: https://en.wikipedia.org/wiki/Multiple_Access_with_Collision_Avoidance_for_Wireless#:~:text=Multiple%20Access%20with%20Collision%20Avoidance%20for%20Wireless%20(MACAW)%20is%20a,is%20adopted%20from%20this%20protocol.Links to an external site. This protocol uses RTS/CTS frames to deal with hidden terminal and exposed station problems. The question is whether MACAW protocol ALWAYS solves the hidden terminal and exposed station problems. Can you construct an example scenario where MACAW protocol may not be able to solve one or both of the problems? The example scenario you construct may be a pathological case which is fine since it indicates that there is a situation in which this protocol is not able to solve the case.
