Amount of delay on extracting information from Big Data

Asked By Kt27ice 0 points N/A Posted on - 09/30/2012

I am researching real time roadway traffic conditions, and since Big Data collects massive amounts of information, what amount of delay is expected from the time the data is collected, transmitted, processed, extracted, analyzed, and given meaningful results?

Amount of delay on extracting information from Big Data

Dear Kt27ice!

While data transmission delay may occur due to many reasons and this delay is often caused by the data-rate of the link. The delay is proportional to the packet's length in bits i.e.:

Where:

 is the delay in transmission.

N is the number of bits, and

R is the rate of transmission (bits/second)

Delay may occur due to many reasons, for example:

1. Queuing Delay

2. Propagation Delay

3. Processing delay

4. Network delays and losses
