How can I get a list of surrounding wireless access points using node.js?

Question

Environment

• Linux Ubuntu
• node.js v0.6.12

purpose

I would like to get a list of available AP / network names (SSID)

I can choose a specific SSID.

My ultimate goal is to test the strength and quality of the Wi-Fi signal in order to force re-association with another access point before it completely loses connection.

How to create a loop that retrieves and updates the list of surrounding access points using node.js?

Would it be a node.jsgood choice for this?

How to get information from the signal strength and quality of the AP ie?
