An Exposed Node Problem by Using Request to Send and Clear to Send in Terminal Wireless Network

The Request-To-Send and Clear-To-Send (RTS/CTS) mechanism is widely used in wireless networks in order to transmit data from source to destination in order to reduce packet collisions (due to hidden node) and, thus, achieve high throughput wireless network. These problems are “Exposed Node Problem”, “RTS -induced and CTS – induced Problem” and “Masked Node Problem”. Leveraging concurrent transmission is a promising way to improve through put in wireless networks. Existing MAC protocols like Carrier Sense Multiple Access (CSMA) always try to minimize the number of concurrent transmissions to avoid collision
