The method comprises the following steps: the number n of stations participated in a contention currently is measured; according to the number n of stations participated in the contention currently, a practical collision probability Pc of a current contention window value CWold and optimal collision probability Pcopt, under the maximum network throughput are acquired; when a data frame is sent successfully, an initial contention window value CWinit is adjusted according to the practical collision probability Pc and optimal collision, probability Pcopt; when a data frame is sent unsuccessfully, a retransmission contention window value CWnew adjusted according to said practical collision probability Pc. The above solution can better reflect network collision situation, adaptively adjust an initial contention window value and retransmission contention window value jointly."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for adjusting contention window value adaptively","description":"A method and device for adjusting contention window value adaptively are disclosed.
