Actually, contrary to what many IM's believe, Google seems to allow sending paid traffic to AdSense sites. You can even advertise using Google AdWords.

Here is an excerpt from their "AdSense Help":

"For example, if you advertise using Google AdWords, you could set up an AdSense channel called "AdWords" to track the AdSense activity coming only from your AdWords campaigns."

However, I would be careful with the type of traffic any advertising program might send to your site.

Google does not allow paid-to-surf traffic, or traffic that gets any type of incentive to visit sites.

So unless you are absolutely sure that the traffic you are sending to your site are legitimate web surfers, I would not take any chances.

There was an Adsense scam on this forum last year called "EasyPPC money". They were claiming to send adsense safe traffic, but everyone who used it got their Adsense account banned.

It just shows you how fragile the adsense business model is, anyone could get their competitors banned if they wanted and appealing to google would do no good because there is no way to prove if it was you who sent the traffic or not.
