Abstract. OLPC's XO laptop was the first laptop to ship with a fully functional mesh stack developed specifically for it. This talk goes over the motivation, the design constraints as well as the consequent engineering choices behind OLPC's mesh stack. It describes the incremental improvements that were made over the course of its development, its shortcomings and the lessons learned. After a brief description of OLPC's application stack, we present usage scenarios and experiences from the field.

Implementing 802.11s: notes from the trenches

Javier Cardona
CEO and Founder

Abstract. Javier Cardona will present some of the challenges that his company, Cozybit, faced when implementing the pre-802.11s mesh stack embedded in the first One Laptop Per Child, and the open source 802.11s stack in the Linux kernel (open80211s).  The talk will cover technical issues like appropriate metric selection and mesh portal discovery. It will also cover not-so-technical topics like how to achieve harmonious coexistence of open and proprietary software licenses (you can't), and what to do about misbehaving legacy 802.11 equipment deployed by major players (don't mess with it). The talk will end with a summary of the the major issues that wireless research needs to address before fulfilling its promise of world domination.
