Can somebody provides code examples to help with max coverage problem?

Hi, i am newbie at Matlab and looking for source codes to help understand how I could evaluate the following coverage problem:

• Create a space (100 x 100 kilometers) and deploy N (user input) nodes in a random way;
• Pick nodes to be the Hub nodes (Each Hub handle max of 10 nodes, producing exatcly N/10 nodes and their reach is a 25 kilometers circle);
• For each space deployment, algorithm should test all possible options and pick the solution with the higher number of covered nodes;
• Not all nodes need to be covered;
• Feel free to suggest changes if my problem can be improved;

I appreciate any help or input.
