The IEEE 802.11 MAC layer protocol adopts the mechanism of Distributed Coordination Function (DCF), which is based on CSMA/CA(Carrier Sense Multiple Access with Collision Avoidance) to perform its fundamental function, wireless medium access control.
IEEE 802.11 的MAC层协议采用基于载波监听/冲突避免(Carrier Sense Multiple Access with Collision Avoidance,CSMA/CA)的分布式协调功能(Distributed Coordination Function,DCF)机制,实现了它的核心功能——无线介质访问控制。
To resolve the problem of data packet collision in Ad Hoc network caused by hidden terminal and exposed terminal, dual channel based multiple access (DCMA) protocols were proposed, which including basic carrier sensing (BCS) protocol and carrier sensing with busy indication (CSBI) protocol.
There are three basic styles of their clash: the duties and the obligations of person conflicts with public manager, job with society, and organization with profession.
A synchronous conflict model for a group of K>amp;gt;1 stations is designed and used in evaluating the stability of the capacity of the random multiple access method with increasing number of stations and the station individual speed.
It is shown that an arbitrary grouped p-element permutation can be implemented in a conflict-free way through the commutation of channels on the double p-ary multiring or the double p-ary hypercube.
A model for a random access network controlled by a static conflict warning protocol is designed as a single-server queueing system with a retrial buffer.
Part I briefly outlines the main results of network game theory-a game theory topic devoted to the formation of stable links between goal-oriented subjects in conflicts.
The effect of one alkene on the arylation rate of another alkene conflicts with the conventional mechanism of the Heck reaction in which the arylated alkene is formed through the unimolecular step of palladium hydride β-elimination.
Besides, other low-power techniques are also adopted for the special baseband-processor which implements complex functions, such as encoding/coding, anti-collision and authorization scheme, and reading/writing operation to EEPROM.
When the density function is high in the center and decreasing with the radius, the collapse process will be described, and in this case, the singularity will only come out in the center because of collision.
Pump and probe shadow imaging and interferometric fringe imaging have been used to determine plasma density, relaxation time, and electron collision time in the conduction band.
In contrast to all other hard reactions studied so far, we encounter a clash between the two definitions of the glue in the pomeron from the inclusive spectrum of leading quarks and the small-β evolution of the diffractive cross section.
This clash casts a further shadow on customary applications of the familiar collinear factorization to a pQCD analysis of diffractive deep inelastic scattering.
The inflator housing is a main part of the curtain-type air bag system, which supplies high-pressure gases in pumping up the air bag-curtain which is increasingly being adapted in deluxe cars for protecting passengers from the danger of side clash.
