A Handoff Algorithm of Dynamic Decisions with Extenics for Wireless Cellular Networks

Algorithm 1

Choose mobile information from database;

Select the current cell number (𝑖) and get the corresponding information;

If 𝑇_{dwell_avg}≥𝑇_{call_avg}

 Then set the value of 𝑤_𝑜𝑓_𝑡(𝑖) to LOW;

EndIf;

Else

 Then set the value of 𝑤_𝑜𝑓_𝑡(𝑖) to HIGH;

EndElse;

While (𝑗∈𝐴, 𝐴 is the set of adjacent cells of cell 𝑖)

Begin

 Set the 𝑤_𝑜𝑓_𝑚(𝑖) to be the value of move probability from cell(𝑖) to cell(𝑗);

 Calculate the accumulation function

    𝐴𝑤(𝑗)=𝑘(𝑣)∗𝑤_𝑜𝑓_𝑘(𝑖)+𝑤_𝑜𝑓_𝑡(𝑖)+𝑤_𝑜𝑓_𝑚(𝑖);

 Sum up 𝐴𝑤(𝑘) (𝑘 is the adjacent cells of cell 𝑗) in cell 𝑗

    𝐴𝑤(𝑗)=∑𝐴𝑤(𝑖);

 Reserve the necessary resource and adjust the number of guard channel in

 cell(𝑗) by total accumulation function 𝐴𝑤(𝑗)

    GCS_num=Totalchannels−𝐴𝑤(𝑗)∗Predict_basis−num_of_new_call;

 Prepare the handoff to the cell(𝑗);

EndWhile;
