Description of Problem:

In the wireless-phyExt.cc line 443-8:

if ( state == SEARCHING && newstate != SEARCHING ) {
       // indicate MAC busy since we are either receiving or sending
       // only if we have not been busy already
       if (powerMonitor->getPowerLevel() < CSThresh_) {
               sendCSBusyIndication();
       }


In line 446, if the power level is less then the carrier sense threhold, a busy flag is raised. However, we should check if the power level is greater than CSThresh_.

Thus, line 446 should be:
if (powerMonitor->getPowerLevel() > CSThresh_)
