Explanation:
Detailed explanation-1: -Solution. The exposed terminal problem is solved by the MAC (medium access control) layer protocol IEEE 802.11 RTS/CTS, with the condition that the stations are synchronized and frame sizes and data speed are the same. RTS stands for Request to Send and CTS stands for Clear to Send.
Detailed explanation-2: -An algorithm called the Multiple Access with Collision Avoidance (MACA) is deployed to solve the hidden terminal problem in wireless networks and avoid collisions. The key idea behind MACA is to have the sender and receiver exchange control frames before the sender transmits any data.
