/**
 * Sample simulation script for radio link failure.
 * By default, only one eNodeB and one UE is considered for verifying
 * radio link failure. The UE is initially in the coverage of
 * eNodeB and a RRC connection gets established.
 * As the UE moves away from the eNodeB, the signal degrades
 * and out-of-sync indications are counted. When the T310 timer
 * expires, radio link is considered to have failed and UE
 * leaves the CONNECTED_NORMALLY state and performs cell
 * selection again.
 *
 * The example can be run as follows:
 *
 * ./ns3 run "lena-radio-link-failure --numberOfEnbs=1 --simTime=25"
