Evolutionary Game Theory-Based Collaborative Sensing Model in Emergency CRAHNs

Algorithm 2

Adaptation algorithm at the SU “𝑖”.

Step 𝟏: Init: Set 𝑀;

   Set 𝑃_𝑠𝑖 = Random value {0 to 1};

    𝐹_𝑠𝑖=0; 𝜇_𝑝=0.02; 𝜇_𝑛=0.2

   iter = 1

Step 𝟐: Make local decisions about spectral occupancy and send to SC

   iter = iter + 1

Step 𝟑: if iter = 𝑀 Observe 𝐹_𝑠𝑖

   If 𝐹_𝑠𝑖<1 and 𝑃_𝑠𝑖<1 set 𝑃_𝑠𝑖=𝑃_𝑠𝑖+Δ𝑃_𝑠𝑖

   else if 𝑃_𝑠>0𝑃_𝑠=𝑃_𝑠−Δ𝑃_𝑠

   iter = 1
