Impact of Resource Blocks Allocation Strategies on Downlink Interference and SIR Distributions in LTE Networks: A Stochastic Geometry Approach

Algorithm 1

Minimizing global interference.
Data:: Total number of RB.
cost: sum of interference for the current allocation.
bestCost: sum of interference for the best allocation strategy, initialized to -1.
Result: Assign an RB to a user. This algorithm is called by the controller for each
new user.
(1)   for  each    do
(2)   if  rb is free  then
(3)   assign rb to this user;
(4)   cost sum_Interference();
(5)   if  bestCost <0 or cost<bestCost  then
(6)   Save this allocation strategy;
(7)   bestCost = cost;
(8)   end
(9)   end
(10) end
(11) Assign the saved allocation strategy
