Loss differentiation based management of wireless networks

An article comprising:

• a computer program product comprising a non-transitory storage medium having stored therein instructions that, if executed, result in:
• providing a first, second, and third packet error rates at a wireless node, wherein:
• the first packet error rate comprises an indication of an interference signal on a channel prior to a communication,
• the first packet error rate is generated by:
• counting T1, the number of packets transmitted in the presence of type 1 interference,
• counting F1, the number of packet transmissions that failed in the presence of type 1 interference,
• counting T2, the number of packets transmitted in the absence of type 1 interference,
• counting F2, the number of packet transmissions that failed in the absence of type 1 interference, and
• calculating the first packet error rate from T1, F1, T2 and F2,
• the second packet error rate comprises an indication of an interference signal on the channel after the communication, and
• the third packet error rate comprises an indication of an interference signal on the channel during the communication;
• modifying a transmission power level at the wireless node in response to the first and the second packet error rates;
• modifying a carrier sensing threshold at the wireless node in response to the first and the second packet error rates;
• and
• modifying a contention window ratio at the wireless node in response to the third packet error rate, wherein the modifying the contention window ratio comprises:
• estimating the contention window ratio at the wireless node by increasing the contention window ratio if the third packet error rate exceeds a maximum third packet error rate value,
• receiving one or more contention window ratios from one or more neighboring wireless nodes, and
• selecting a maximum contention window ratio from among the estimated contention window ratio and the received one or more contention window ratio values.
