How it will work,

Start with the random environment.
- For this you will use coordinates to keep track of CPEs, they can be static
- You will need these coordinates to calculate the distance of the PUs
A lot of users will connect to the nodes I (based on only distance)
This will happen because they will all sit very close to the node and first connection is based strictly on distance from the node
Once this is done, we can show how our paper will do it, you don't have to implement this, we will use their results from the paper.
Now we start with SELA
You will go through and look at the table of each CPE (node)
Each CPE will have the criteria mentioned in page two of the scan
You will already have calculated the distance of each PU to each node.
Ignore all idle (inactive nodes)
If the distance is greater than 100m, we consider that as idle for that PU
You will then calculate how many PUs are connected to a node (CPE)

Then calculate how much power each CPE has (assign each one 100)
1 unit of power can support one PU
You will then calculate the SINR (this is simply based on total bandwidth/# PUs) for each CPE
Now, for the probabilities
If the CPE is idle you give it a 0 (impossible to connect - flag set)
If the CPE is too far > 100 you give it a 0 (impossible to connect - flag set)
If the CPE doesn't have enough power you give it a 0 (impossible to connect - flag set)
I have written out the rest of the probabilities in sheet 2 and 3
Now, take all the probabilities and add them together based on weightings for each node for each PU (summation formula – very simple)
Now, when you add these, they will give you a number that will be your estimator (vector)
Select the CPE with the highest estimator and that is the one you will connect the PU to
After you connect the PUs you update your information
Set the current vector as the old vector
Now calculate a new vector as you did before and start all over
