• Multiple Access with Collision Avoidance for Wireless — (MACAW)[1] is a slotted Medium Access Control (MAC) protocol widely used in Ad hoc networks.[2] Furthermore, it is foundation of many other MAC protocols used in Wireless Sensor Networks (WSN).[2] The IEEE 802.11 RTS/CTS mechanism is adopted from …   Wikipedia

• Multiple Access with Collision Avoidance — (MACA) is a slotted media access control protocol used in wireless LAN data transmission to avoid collisions caused by the hidden station problem and to simplify exposed station problem. The basic idea of MACA is a wireless network node makes an… …   Wikipedia

• Channel Division Multiple Access (ChDMA) — is a simple multiple access scheme developed for low duty cycle UWB networks. The idea lies in the fact that different users have different channel impulse response (CSI) and the signal at the receiver can be rebuilt based on this information.… …   Wikipedia

• Time division multiple access — This article is about the channel access method. The name TDMA is also commonly used in the United States to refer to Digital AMPS, which is an obsolete mobile telephone standard that uses TDMA to control channel access. Time division multiple… …   Wikipedia

• Multi-carrier code division multiple access — (MC CDMA) is a multiple access scheme used in OFDM based telecommunication systems, allowing the system to support multiple users at the same time. MC CDMA spreads each user symbol in the frequency domain. That is, each user symbol is carried… …   Wikipedia

• Multi-frequency time division multiple access — MF TDMA (Multi Frequency, Time Division Multiple Access) is the leading technology for dynamically sharing bandwidth resources in an over the air, two way communications network. Many variations of MF TDMA technology (including simple TDMA) exist …   Wikipedia

• Carrier sense multiple access with collision avoidance — In computer networking, CSMA/CA belongs to a class of protocols called multiple access methods. CSMA/CA stands for: Carrier Sense Multiple Access With Collision Avoidance.In CSMA, a station wishing to transmit has to first listen to the channel… …   Wikipedia

• Frequency-division multiple access — or FDMA is an channel access method that is used by radio systems to share a certain radio spectrum between multiple users. The users are individually allocated one or several frequency bands, allowing them to access the radio system without… …   Wikipedia
