Presentation: An Overview of the Experimental Research at Wireless Information Network Laboratory (WINLAB)
Speaker: Ivan Seskar, Associate Director for Information Technology
Ivan Seskar is Associate Director at WINLAB, Rutgers University responsible for experimental systems and prototyping projects. He was a lead project engineer for ORBIT, with responsibility for development, integration and deployment of the radio grid emulator system for which the team received 2008 Alexander Schwarzkopf Prize for Technological Innovation. He is currently a PI for the Rutgers OpenFlow meso-scale deployment and a co-PI for the "Open WiMAX Base Station" project and related WiMax meso-scale deployment. Mr. Seskar's research group is currently working on various aspects of MobilityFirst architecture implementation and on a cognitive radio platform that is targeted for GENI deployment. Ivan is also a co-founder and CTO of Upside Wireless Inc.
Abstract: Founded in 1989, WINLAB has grown to be among the oldest and most respected globally recognized wireless research centers. In this talk we will present a brief overview of research activities at WINLAB followed by more detailed presentation of wireless related design and prototyping efforts with emphasis on three large projects: ORBIT wireless testbed, Global Environment for Network Innovation (GENI) and MobilityFirst future Internet architecture.
The ORBIT testbed consists of an indoor radio grid emulator for controlled experimentation and an outdoor field trial network for end-user evaluations in real-world settings. We will describe the radio grid system architecture including an identification of key hardware and software components. We will also discuss software design considerations for the open-access radio node, and for the system-level controllers that handle management and control of the testbed as well as the process of specifying and running experiments. We will also describe the motivation and design of the ORBIT testbed extensions which support research and experimentation with several emerging wireless scenarios - next generation cellular, ad-hoc vehicular and cognitive radios.
GENI is the National Science Foundation's effort to build a national at scale facility that will support research on "clean slate" designs and architectures for future global communications networks. Wireless technologies are viewed as one of the main drivers of the future networks and as such play a prominent role in GENI. After a very brief introduction of GENI we will discuss in more detail WINLABs participation in GENI and especially the three projects:
- WiMAX Meso-Scale Deployments: "GENI-enabled" WiMAX technology is currently deployed across eight university campuses. The goal is to create a mobile networking playground that will span the country, and provide experimental services to a large number of users using commercially available equipment.
- OpenFlow Meso-Scale Deployments: The goal of this project is to deploy OpenFlow enabled equipment at eight university campuses. This deployment will be used not only for GENI research and prototyping but also for day to day campus network management. Some of the campuses will also use it connect to Internet2 and NLR so that it will eventually lead to a nation-wide sliceable interconnected OpenFlow network.
- CR-GENI: The scope of this project is to develop a set of ruggedized, expandable and configurable multiradio cognitive radio systems that will facilitate experimentation by GENI researchers who have only limited experience with hardware development tools.
The last part of the talk presents an overview of the MobilityFirst network architecture, which is a clean-slate project being conducted as part of the NSF Future Internet Architecture (FIA) program with an introduction of key protocol components of the proposed architecture including:
a) fast global name resolution service,
b) self-certifying names for network objects,
c) hybrid name/address based routing,
d) in-network storage at routers,
e) hop-by-hop transport, and
f) location or context-aware services.
This is followed by the introduction of experimental prototyping and evaluation efforts for the MobilityFirst protocol stack in representative mobile usage scenarios such as hybrid WiFi/cellular, ad-hoc/mesh, vehicular and machine-to-machine (M2M) and concludes with a description of an ongoing multi-site GENI experimental deployment.
