Congestion Control and Prediction Schemes Using Fuzzy Logic System with Adaptive Membership Function in Wireless Sensor Networks

Algorithm 2

Membership adjustment using BAT.

Objective function f(x) =

Initial population size

Initial maximum iterations , pulse rate , loudness , velocity v_i.

Define pulse frequency

while ()

Generate new solutions by adjusting

Update vi and

if (rand() → )

Select a solution and generate a local solution

end if

Generate a new solution with a random flying pattern

if (rand() <   &   < )

Accept new solution

Increase and decrease

end if

Rank the bats and find the optimal using ED

end while
