In computer networking and telecommunication, collision-avoidance methods try to avoid resource contention by attempting to avoid simultaneous attempts to access the same resource. Collision-avoidance methods include prior scheduling of timeslots , carrier-detection schemes, randomized access times, and exponential backoff after collision ...
Carrier-sense multiple access with collision avoidance (CSMA/CA) in computer networking, is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by beginning transmission only after the channel is sensed to be "idle". [1] [2] When they do transmit, nodes transmit their packet data in its entirety.
A remote collision, in CSMA/CD computer networks over half-duplex media (10BASE5 or 10BASE2), is a collision that occurs when a frame shorter than the minimum length is transmitted. This frame may cause a collision at the remote end which cannot be detected by the transmitter, so the frame is not resent on the physical layer.
In contention, any computer in the network can transmit data at any time (first come-first served). This system breaks down when two computers attempt to transmit at the same time. This is known as a collision. To avoid collisions, a carrier sensing mechanism is used. Here each computer listens to the network before attempting to transmit.
CSMA/CD is used to improve CSMA performance by terminating transmission as soon as a collision is detected, thus shortening the time required before a retry can be attempted. CSMA/CD is used by Ethernet. Carrier-sense multiple access with collision avoidance In CSMA/CA collision avoidance is used to improve the performance of CSMA.
In computer networking, carrier-sense multiple access with collision avoidance and resolution using priorities (CSMA/CARP) is a channel access method.CSMA/CARP is similar in nature to the carrier-sense multiple access with collision detection (CSMA/CD) channel access method used in Ethernet networks, but CSMA/CARP provides no detection of network collisions.
Common statistical time-division multiplexing multiple access protocols for wired multi-drop networks include: Carrier-sense multiple access with collision detection (CSMA/CD), used in Ethernet and IEEE 802.3; Multiple Access with Collision Avoidance (MACA) Multiple Access with Collision Avoidance for Wireless (MACAW) Carrier-sense multiple ...
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 the foundation of many other MAC protocols used in wireless sensor networks (WSN). [2] The IEEE 802.11 RTS/CTS mechanism is adopted from this protocol.
