Research & Projects

Picture of student doing research in the Real-Time Communications Lab

The IIT RTC Lab hosts projects in these major areas:

  • Mobility
  • NextGen 9-1-1 (NG9-1-1)
  • IP-based Real-Time Communications (SIP and associated protocols)
  • Web-based real-time communications (WebRTC)
  • Security
  • Real-Time Media

Test Beds and Project Areas:

  • Network Transport and Performance (NTAP) - This is a multi-domain, multi-level test bed whose routers, switches and servers are configurable to create different network where we study the behavior and performance characteristics of both WebRTC-based and SIP applications and services.
  • Next Generation 9-1-1 (NG9-1-1) - These testbeds allow the user to place an end-to-end call for emergency services from a POTS phone, a SIP phone, a mobile phone or a WebRTC-based application to a Public Service Answering Point (PSAP) using an Emergency Services IP Network (ESINet). The lab has three of these networks. Two are for experimentation and research. The third is used for the National Emergency Numbers Association (NENA) Industry Collaboration Events (ICE).
  • Mobile-RTC - This testbed at uses several software defined network applications to form a captive GSM network on which we study and test the flow through and performance of messages between wired and wireless systems…..
  • Voice over IIT (VoIIT) - This SIP-based telephone service was built by students and is used in lab exercises and projects to demonstrate and test the flow of SIP messages in various applications and configurations….
  • Web-Dev - This is a collection of virtual and physical servers and large screen monitors in the Main Campus lab where students can develop real time communications applications. This collection of servers is also available via remote login.
  • Real-Time Media (RTM) - The growing volume and variety of real-time media applications is a challenge to network operators due to the unpredictable volume and character of data traffic they present. RTC Lab projects study the ways these applications use resources and how impairments in the network affect the user experience.

RTC Student Projects

The goal of this project is to provide a 911 operator with the indoor location of a person placing a 911 emergency call from a mobile phone. The indoor location must include the floor and room number where the caller is located.

The SIP Performance Project is one of the oldest on-going projects in the Real-Time Communications Lab at Illinois Institute of Technology. It was developed while Lab Director Carol Davids and her colleagues were writing and revising the newly adopted IETF RFC’s 7501 and 7502.

The goal of this project is the creation of a SIP-based telephone service for the Illinois Institute of Technology (IIT) community. Subscribers will be able to use smartphones, laptops and desktop computers to engage in audio-video calls and get voice mail using this service.

This project measures the maximum Session Initiation Protocol (SIP) throughput and rate of sending invite/call with no errors that a SIP proxy can support. We have learned to operate the SIPp tool and also studied the draft RFCs that described the method of testing.

In the Fall and Spring semesters of 2013 and 2014, Sushma Sitaram implemented a Global System for Mobile communications (GSM) access point using OpenBTS that is able to use GSM-compatible phones over a VoIP network.
