CSMA/CA全称carrier sense multiple access with collision avoidance,即载波侦听多路访问/冲突避免,如上文描述,它提供了设备接入信道的规范,适用于无线场景,这里科普一下,与其相对的是有线场景下类似的机制被称为是CSMA/CD,二者存在以下不同点: (1)CSMA/CD是一种检测冲突的机制,CSMA/CA是避免冲突的机制; (2)CAM...

DCF Models for Valuation of Non-listed Firms in China贴现现金流模型被大多数关于公司收购的文献认为是最科学,最成熟的价值评估方法.该模型将公司价值定义为公司预期现金流产生的时间,大小以及与预期现金流相关的风险三者的函数,其基本原理是,任何资产的价值等于其预期未来全部现金流的现值总和.由于预期现金流的特性...
CSMA/CA的全称是Carrier Sense Multiple Access with Collision Avoidance,即载波侦听多路访问/冲突避免。如果熟悉有线网络的可以知道,在集线器与中继器中也会采用一种CSMA/CD的机制,从协议设计的大思路上,两者是类似的,或者说两个都是基于CSMA机制的,而细节上,两者有很多的出入,在本文中,我们尚不细致讨论两者协议的...
The method is simple, efficient and easy to implement in comparison to point coordination function (PCF), another access method in IEEE 802.11 based on access points (base stations). Simulations are conducted to analyze the proposed scheme. The results show that DCF is able to carry the ...

A Priority Backoff Algorithm (PBA) for IEEE 802.11 DCF is presented in this paper. The basic idea of PBA is each station should collect statistical data of other stations' transmission while sensing the channel, and maintaining a sent data table for all
Discounted cash flow (DCF) is a valuation method used to estimate the attractiveness of an investment opportunity. Learn how it is calculated and when to use it.
