advertisement-server

I want to show a view in bottom of my application, to show ads, that fetch from my own Linux server. The important point is that i want to have my own control panel in server side. So i can't use AdMob, Google Ads SDK, ... or every SDK that doesn't have open source server side panel. I searched too much, and found many open source project (client and server side), but i'm confused. 1-Whats is publisherId? 2-Can i fetch ads from my own server? Is there any open source library in both side?(client and server)? Or if there is not, With which opensource library I can fetch ads from my own server?

I'm going to create an adserver by myself like google adsense. But I need to know few things to plan my project. I searched in many ways with google but I couldn't find clearly explained things that I need to know. I search in Stackoverflow but the results didn't explained me a much. So don't misunderstand this as a duplicate and don't misunderstand about me as I may not researched much(Because I tried it before post this). This is a sample google ad code <– Begin Google Adsense code –> <script type=”text/javascript”> google_ad_client = “ad-client-code-goes-here”; google_ad_slot = “ad-slot
