What is NAV in wireless network?

What is NAV in wireless network?

The network allocation vector (NAV) is a virtual carrier-sensing mechanism used with wireless network protocols such as IEEE 802.11 (Wi-Fi) and IEEE 802.16 (WiMax). The virtual carrier-sensing is a logical abstraction which limits the need for physical carrier-sensing at the air interface in order to save power.

What is the purpose of NAV in CSMA CA?

The network allocation vector (NAV) is a virtual carrier sensing mechanism that forms an important part of the carrier sense multiple access with collision avoidance (CSMA/CA). It is implemented in wireless network protocols, IEEE 802.11 and IEEE 802.16, which operates in the medium access control (MAC) layer.

What is purpose of NAV?

: The Navigation Section element The HTML element represents a section of a page whose purpose is to provide navigation links, either within the current document or to other documents. Common examples of navigation sections are menus, tables of contents, and indexes.

What is RTS and CTS in networking?

RTS/CTS (Request To Send / Clear To Send) is the optional mechanism used by the 802.11 wireless networking protocol to reduce frame collisions introduced by the hidden node problem.

What is DCD DSR DTR RTS CTS?

A: 1、DCD Data Carrier Detect. DTR Data Terminal Ready. DSR Data Set Ready. RTS Request To Send.

What is DTS and RTS?

RTS means Ready Request To Send and its counterpart is CTS Clear To Send. DSR means Data Set Ready and its counterpart is DTR Data Terminal Ready.

What is NAV stand for?

Net asset value
“Net asset value,” or “NAV,” of an investment company is the company’s total assets minus its total liabilities.

What is DCD in serial port?

Data Carrier Detect, abbreviated as DCD, or alternately Carrier Detect abbreviated as CD, is a control signal present inside an RS-232 serial communications cable that goes between a computer and another device, such as a modem.

What is CTS and DTR?

DTR: Data Terminal Ready. DSR: Data Set Ready. RTS: Request to Send. CTS: Clear to Send.

What is DTR and DSR?

Data terminal ready (DTR), another form of hardware flow control, is normally generated by the devices, such as printers to indicate that they are ready to communicate with the system. This signal is used in conjunction with data set ready (DSR) generated by the system to control data flow.

Can you have multiple NAV tags?

Yes, absolutely. You can have multiple header , nav , and footer tags sans penalty.

Where do you put NAV?

The nav tag is reserved for primary navigation areas, like the main menu across the top of the page or section. A document may have several nav elements, for example, site navigation and one for intra-page navigation.

What is the difference between NAV and DCF?

1. A NAV model assumes that the company never increases its existing reserves, so there is no additional CapEx in future years beyond what is required to develop existing reserves. 2. A DCF model is done at the corporate level, but you run a NAV model at the asset level.

How is NAV decided?

NAV is calculated by dividing the total value of all the cash and securities in a fund’s portfolio, minus any liabilities, by the number of outstanding shares. The NAV calculation is important because it tells us how much one share of the fund should be worth.
