Outputs: MAC tput. Test 2b: Deferral Test 2 Goal: This test case is designed to verify whether the simulator can correctly handle deferral procedure after collision happens with the existing of hidden nodes. Assumptions: AP1 and AP2 can not hear each other. ( ever) Interference Assumptions: If any part of an MPDU sees interference, that MPDU should fail If any part of a data preamble sees interference, all MPDUs should fail If an MPDU, or data premable sees no interference, it should pass If an ACK overlaps with the transmission of an OBSS AP, the PER on the ACK should be 0. (i.e. the ACK should pass) Backoff If no ACK is received, the transmitter should double it’s CW. If an ACK is received, the transmitter should reset its CW If no MPDUs are decoded, no ACK should be sent. After 10 missing ACKS, the CW should be reset. PER definition PER= 1-Acked data MPDUs/Total data MPDUs sent ( TPUT can be computed from number of successfully ACKed MPDUs and the total time) data MPDUs are measured by the transmitters
