Carrier Sense Multiple Access with Collision Avoidance. However‚ simple CSMA is susceptible to the hidden node problem‚ especially in so called ad hoc networks where a node may communicate directly with every other node in range or using intermediate nodes as relays otherwise. Hidden nodes cause costly packet collisions and thus significantly affect network performance. In order to combat the hidden node problem‚ a mechanism known as Request to Send/Clear to Send (RTS/CTS) handshake is often used. RTS/CTS

Introduction Wireless network is indicated to a telecommunication network whose interconnections between nodes are implemented without the use of wires‚ such a computer network. Nowadays‚ wireless network has become the important thing in telecommunication. This sort of technology has been used for over a century and remains synonymous with radio. In 19th century‚ Guglielmo Marconi invented a radio and made his made his mark in the world of wireless technology. At that moment‚ Marconi was about
