    • M&M: Multicast-based Architecture for Mobility Management
    This project investigates problems of IP mobility management and efficient handoff for wireless (cellular and all-IP) networks. It addresses issues of address assignment, micro-mobility, handoff performance for mobile nodes.

    • STRESS : Systematic Testing of Robustness by Evaluation of Synthesized Scenarios
    The overall objective of STRESS is to provide tools and methodologies
  • For systematic design and verification of networks to enable rapid deployment of robust network protocols
  • To increase the robustness of newly deployed protocols and applications through automated test generation and their integration with simulation tools.
  • STRESS also aims to provide a more complete performance characterization of network and end-to-end protocols through sensitivity analysis.
  • Refined network planning models (for high performance and reliability)

    • VINT/NS Virtual InterNetwork Testbed
    VINT is a DARPA-funded research project whose aim is to build a network simulator that will allow the study of scale and protocol interaction in the context of current and future network protocols. VINT is a collaborative project involving USC/ISI, Xerox PARC, LBNL, and UC Berkeley.

    • PIM
    maintains the traditional IP multicast service model of receiver-initiated membership; uses explicit joins that propagate hop-by-hop from members' directly connected routers toward the distribution tree. builds a shared multicast distribution tree centered at a Rendezvous Point, and then builds source-specific trees for those sources whose data traffic warrants it. is not dependent on a specific unicast routing protocol; and uses soft-state mechanisms to adapt to underlying network conditions and group dynamics.

    • IMPORTANT
    Our IMPORTANT (Impact of Mobility Patterns On RouTing in Ad-hoc NeTworks) framework aims to evaluate the impact of mobility on the performance of MANET routing protocols. We propose some protocol-independent metrics to capture the characteristics of mobility. In addition, a rich set of mobility models that span the metric space is carefully chosen to evaluate the various protocols (i.e., DSR, AODV and DSDV). Finally, we attempt to relate the protocol performance (throughput and routing overhead) with mobility models through the connectivity graph between the nodes.
