COMSOC-2016 Program

The COMSOC-2016 program consists of three invited talks, 34 oral presentations and 21 poster presentations of contributed papers, which have been selected amongst 70 submissions received by the program committee.

Each invited talk is 60 minutes long. Contributed talks have been allocated 20 minutes each, including questions and change-over to the next speaker. Accepted papers with poster presentation will be shown during all three days of the workshop. There are two dedicated poster sessions of one hour each, and an additional open poster session on Friday.
