We add mobility support design to SECON. Our design allows a user to submit a keyword-based query while attached to one WiFi to receive reply at another attached WiFi after the user has moved. Furethermore, we enhance the scalability of our design such that (a) a user can submit a duration-based subscription to a publisher, (b) organization that deploys CRS decide if published contents from publishers should only be hosted at CRSes which belong to Tier1/Tier2 ASes. Description of our design and Our large scale simulation results can be found in the following SCOM paper which appeared at IEEE MSN 2013 conference. Simulation code for SCOM will be released in the near future.
We have added real-time video event subscription feature to SECON. We gave a demonstration of our enhanced prototype at GENI GEC19 meeting in March 2014. See below for our GEC19 poster
We have recently designed an efficient mobile visual search system (Emovis) where users are allowed to submit images of buildings to retrieve some information related to the buildings. Later, keyword-based queries can be issued to retrieve more information. Interested reader can refer to our IEEE MSN 2013 paper related to EMOVIS.
