Detailed Description

A SnrEval for the 802.11b protocol.

Subclass of SnrEval. Basically the same except for some extra parameters of 802.11 and the duration of the packet that has to be computed differently as the modualtion of header and data part of the packet are different. This module forms a physical layer together with the Decider80211 module. The resluting physical layer is intended to be used together with the Mac80211 module.

Member Function Documentation

double SnrEval80211::calcDuration (  cMessage *  frame  )  [protected, virtual]

computes the duration of a 802.11 frame in seconds The duration of the packet is computed, with respect to the different bitrates of header and data. The header is sent with 1Mbit/s and the rest with the bitrate encoded in the frame Reimplemented from SnrEval.

AirFrame80211 * SnrEval80211::encapsMsg (  cMessage *  msg  )  [protected]

This function encapsulates messages from the upper layer into an AirFrame, copies the type and channel fields, adds the headerLength, sets the pSend (transmitterPower) and returns the AirFrame. Reimplemented from BasicSnrEval.

void SnrEval80211::handleMessage (  cMessage *  msg  )

Called every time a message arrives -- we need to call a different encaps msg. Call the right processing functions Reimplemented from BasicSnrEval.
