RETRANSMISSION SCHEME FOR MAINTAINING PERFORMANCE FOR WIRELESS COMMUNICATIONS IN THE PRESENCE OF PERIODIC INTERMITTENT INTERFERENCE

摘要

The present invention can set the default retransmission algorithm and interference retransmission algorithm. Default retransmission algorithm can be DCF-based algorithm is implemented in the MAC layer according to IEEE 802.11-based standard. Minimum cumulative back-off time for the default retransmission algorithm can be less than the minimum cumulative back-off time for the interference retransmission algorithm. Minimum cumulative back-off time for the interference retransmission algorithm can be less than one and greater than the sum of the off-cycle of the on cycle of the PII PII (for example, caused by the microwave oven for PII ~ between 8.3 ms and ~ 16.7 ms) . The decision as to whether the PII is present can be made. If it does not exist, the default retransmission algorithm can be used automatically for wireless data transmission. When PII is present, there is interference retransmission algorithm can be used automatically.
