The official ACM standard format for conferences is given at ACM's web site, and templates exist in several places (SIGMOD, ACM latex, alternate latex).
Unfortunately, Sensys requires a 10 point format instead of the ACM standard 9 point format. SIGCOMM requires a 10 point format for submission and then expects authors to change to the 9 point format for publication!
Consequently I have modified one of the several 9 point ACM styles to support 10 point as an option. Shifting between the styles is just a [9pt] or [10pt] option to \documentclass.
