When you first arrive, look around the room, to get a scope of what is where and what (in a general sense) groups there are.

Find people to talk with. Many groups are not pre defined, and are more random. A group of 2 stay away from, as they are having a conversation. Find some group of 3 or more. Walk up, await the person talking to pause and look at you. Now the hard part Hand out to the person who was talking, and introduce yourself.

Of course if getting involved is too tough, then just listen and smile. Smile, Smile. You are never dressed without a smile.
