SenseDev'17 Experience


SenseDev is a five-day workshop on wireless sensor networks hosted by the University of San Carlos Talamban Campus in Cebu City last March 20-24, 2017. The resource persons were from Coventry University. Participants came from all over the country, mostly from Luzon. Before the actual workshop, we were asked to prepare a virtual machine (for VirtualBox). The virtual machine setup was automated using vagrant using a vagrant file provided by the resource persons. Included in the virtual machine are source code for TinyOS and OMNET++ for programming the TelosB mote. The first day of the conference included a field trip and socials night. The remaining days were devoted to the actual workshop. We were divided into groups where each group must develop a simple project to be presented at the last day of the workshop. Our project won the best project award.
