The use of wireless networks has been drastically increased due to the popularity of mobile devices, such as smart phones and tablet personal computers. In such scenario, a large number of devices associated with network can overlap with each other, causing the hidden-node problem to occur more easily. Hidden terminals are intermediate sources that can reduce the throughput of a wireless network if it applies MAC protocol. The RTS/CTS mechanism is a popular solution to this problem. RTS/CTS (Request To Send/Clear To Send) mechanism is a reservation scheme used in the wireless networks.
