As part of the project ITSUMO (Internet Technologies Supporting Universal Mobile Operations) involved primarily in the mobility management, real-time QoS management, localized multicast and session control signaling part of the architecture that includes Mobile IP,   SIP, SAP, RTSP, SDP and IPv6. Designed, directed and implemented an all IP Mobile multimedia comprehensive test-bed involving many Linux based systems, Cisco routers and several  subnets to demonstrate micro, macro and global mobility including AAA functionality and application layer mobility management such as SIP-based mobility in a 802.11B environment. Many of the features for Wireless Internet Telephony and Streaming Multimedia such as signaling, registration, binding, location management, AAA, and QoS have been prototyped in this testbed.

 

¨       As one of the Co-Principal Investigators (Co-PI) for DARPA ACN project, led in writing the winning proposal for Integrated Mobility Management for phase II and phase III, and have been acting as a Technical lead for the Integrated Mobility Management part of the project. This involved designing and   implementing   an Integrated Mobility Management scheme for Adhoc type military networks while coordinating between different task groups, presenting regular milestone reviews at DARPA meetings.

 

¨       As a technical lead for a DARPA funded AJCN project, involved in the design, development and prototype demonstration of a SIP based multiparty conference control using both multicast and MCU based approaches  aided by  SIP’s third-party call control features.

¨       Acted as a technical lead for two task   groups   that involve design and implementation of  SIP based mobility management and Localized Multicast based architecture for a Motor company's mobile

content delivery network in an all IP wireless environment involving advanced Telematics features.

 

¨       As part of    Network Appliance project involved in the design and implementation of  SIP User Agent, SIP proxy to control the appliances   which are behind the residential gateway. This may involve proposing some extensions to SIP specifications.

 

¨       Study, analysis, and design of a scalable session control architecture based on available H.323 and IETF protocols (SIP, RTP, RTSP, SDP, MGCP) and TINA-C to support VoIP and multi-party and multi-media features over IP or ATM based network. This included the design of end-to-end call flows for establishing the sessions. This work was done for the Regional Bell Operating Companies and other international clients who are planning to build the multi-service platform.

 

¨       Performance Analysis of  SS7 signaling over TCP/IP for VoIP type of services. This was analyzed using IP’s differentiated services (WFQ) on a Cisco 7500 series router and a range of UDP cross traffic.

 

¨       Analyzed and modeled Internet backbone architecture using IP/PPP/SONET, IP/ATM/SONET, IP/DWDM, IP/DPT technology for various kinds of network operators (Enterprise, ISPs, RBOCs). These alternatives were analyzed using ring topology and were also customized to the customer’s mesh/partial mesh type of  network. It included cost, engineering aspects and capacity planning   of various topologies discussed.

 

¨       Scalability analysis of  IP multicast deployment over the Internet, with respect to routing, charging, security and heterogeneity of the network.
