An Enhancement of RTS/CTS Control Handshake in CSMA/CA Based Mac Protocol for an Efficient Packet Delivery Over Multihop Wireless Mesh Network (WMN)
The Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) based Medium Access Control (MAC) protocol uses a short Request-To-Send (RTS) and Clear-To-Send (CTS) control packets prior of actual data packet transmission. The function of the CSMA/CA based MAC protocol in wireless communication is to facilitate wireless nodes (i.e. laptop, PC, smart phones and etc) to access a wireless medium efficiently. Besides, it is also efficiently manage the wireless medium when more wireless nodes involving in transmission activity in the network.
