Overview

New wireless technologies allow mobile users to have easy access to real-time data, and stay connected with business partners, colleagues and friends. However, emerging mobile applications are data-centric but existing IP oriented communication paradigms are not flexible enough to support this. Additionally, serious security and privacy concerns have also been raised. To fully support emerging mobile applications, we are developing a next generation mobile network called SECON that supports mobile content centric networking features. In this project, we will demonstrate new mobile internet features via prototyping and large scale experimentations using GENI testbeds. Key features include (i) intra and inter-domain intentional-named message dissemination, (ii) efficient mobile content centric networking protocol design, (iii) data-centric security with search capability.

Unique features in SECON include (i) intentional named message delivery, (ii) push/pull content dissemination, (iii) keywword-based user interests, (iv) secure content publication with fine-grained access control

We have recently given a demo at NSF GEC12 meeting where our preliminary prototype is run at multiple virtual machines inside a Lehigh laptop that communicate with multiple machines at PlanetLab. Our software provides GUI interface to allow publishers/subscribers to send content publish and user interest announcement messages. We also provide GUI for content resolution servers to show all the CPAs/UIAs that they receive.

Receiving Data Contents

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.
