P6. In step 4 of the CSMA/CA protocol, a station that successfully transmits a frame begins the CSMA/CA protocol for a second fr

ame at step 2, rather than at step 1. What rationale might the designers of CSMA/CA have had in mind by having such a station not transmit the second frame immediately (if the channel is sensed idle)?

Answer:

To avoid collision of transmitting frames.

Explanation:

CSMA/CA, carrier sense multiple access is a media access control protocol of wireless networks that allows for exclusive transmission of frames and avoidance of collision in the network. When a frame is not being sent, nodes listening for an idle channel gets their chance. It sends a request to send (RTS) message to the access point. If the request is granted, the access point sends a clear to send (CTS) message to the node, then the node can transmit its frame.

Many nodes on a wireless network are listening to transmit frames, when a frame is transmitting, the node has to wait for the access point to finish transmitting, so it sends a RTS message again to exclusively transmit a second frame.

Mice21 [21]

Answer:

we need PLC(Programmable Logic Units) attached to the sensors  and those sensors will take the signals/values  and transfer them to the cloud .In cloud we store that information and send that information to the web application where user is able to view

Explanation:

it looks like a SCADA system. we can integrate PLC with SCADA

or

for developing PLC we can use c or c++.it contain logic to transfer data to cloud

for cloud storage we can use Microsoft azure which is useful for data storage in sql servers

for web application we can use ASP.Net to interact with cloud and get data from there and display the results to the user on UI
