Proceedings of the 2nd International Workshop on Hot Topics in Wireless

It is our great pleasure to welcome you to the Second ACM Workshop on Hot Topics in Wireless (HotWireless 2015). This year's HotWireless continues from where we left off last year. It has an exciting program focused on disruptive wireless technologies and systems that can enable orders of magnitude improvements in performance and novel wireless applications. HotWireless strives to provide a launching pad for bold and visionary ideas, and to bring together experts in hardware, physical layer, networks, and systems to address core technical challenges in these emerging wireless technologies. This year we received 16 submissions, of which we selected 10 for publication. The program committee consisted of 19 wireless experts from around the world, who did a fantastic job to provide an average of 4 reviews per paper. The accepted papers this year include exciting topics, which range from indoor localization and 3-D mapping, to low level wireless communication, to communication with UAVs using free space optics. In addition to the accepted papers, we will also have invited talks from several wireless experts. We look forward to your active participation in this workshop!
