Distributed coordination function (DCF) is the fundamental medium access control (MAC) technique of the IEEE 802.11-based WLAN standard (including Wi-Fi).DCF employs a carrier-sense multiple access with collision avoidance (CSMA/CA) with the binary exponential backoff algorithm.
Distributed computing is a field of computer science that studies distributed systems, defined as computer systems whose inter-communicating components are located on different networked computers. [1] [2] The components of a distributed system communicate and coordinate their actions by passing messages to
C-Linda or TCP-Linda - the earliest commercial and a widespread implementation of virtual shared memory for supercomputers and clustered systems from Scientific Computing Associates, founded by Martin Schultz. JavaSpaces - a Java-based tuplespace implementation that helped popularize distributed computing.
A fundamental problem in distributed computing and multi-agent systems is to achieve overall system reliability in the presence of a number of faulty processes. This often requires coordinating processes to reach consensus, or agree on some data value that is needed during computation.
This is where a quorum-based technique comes in. The fundamental idea is that a transaction is executed if the majority of sites vote to execute it. Every site in the system is assigned a vote V i. Let us assume that the total number of votes in the system is V and the abort and commit quorums are V a and V c, respectively. Then the following ...
A distributed control system (DCS) is a computerized control system for a process or plant usually with many control loops, in which autonomous controllers are distributed throughout the system, but there is no central operator supervisory control. This is in contrast to systems that use centralized controllers; either discrete controllers ...
“Distributed” or “grid” computing in general is a special type of parallel computing that relies on complete computers (with onboard CPUs, storage, power supplies, network interfaces, etc.) connected to a network (private, public or the Internet) by a conventional network interface producing commodity hardware, compared to the lower efficiency of designing and constructing a small ...
A distributed system with robust and elastic computation on unreliable and failing resources that are loosely coupled; Coordination of the actions and communication of the nodes; Subsamples of large data sets and online machine learning; There are many reasons for wanting to distribute intelligence or cope with multi-agent systems.
