MINESTRONE: Mobile INfrastructure Enablers for STReaming Optimization and NEw Services
(2003-07)

MINESTRONEThe future of data communications will critically depend on new technical advances that can integrate into wireline infrastructure a large variety of wireless services such as wireless LAN, cellular networks, and wireless personal area networks (WPANs). In order to provide high quality services ubiquitously and flexibly, wireless data services must often bridge the last critical link. Compared to traditional voice services over cellular networks, emerging mobile services such as multimedia streaming, gaming, and real-time visualization require low latency, low jitter, and high bandwidth connectivity end-to-end across heterogeneous networks. The new wireless Internet and modern applications challenge the underlying assumptions of the current protocol and network architecture.

The goal of the MINESTRONE project is to design and develop light-weight, intelligent agents, called enablers, to support emerging applications across heterogeneous transit networks. Since multimedia streaming is highly demanding in terms of bandwidth, delay and jitter constraints, it is considered a representative workload to drive the design of MINESTRONE. The enablers are strategically located in the wireless as well as fixed networks to continuously monitor the routing dynamics and channel quality, detect faults, and automate service restoration/recovery. The enablers, working in collaboration or in isolation, provide services that are not otherwise possible for endpoint-only streaming system.

We have pursued the following research tasks in the MINESTRONE project:

  • Multi-Source Multi-Path Streaming over Wireless Mesh Networks
    We consider the scenario of wireless mesh networks where multipath diversity could be leveraged to combat interference and time-varying channel quality. We study concurrent video streaming with error protection in this scenario.
  • Mobility- and Energy-aware Peer Selection and Rate Allocation
    Our approach takes into account node mobility pattern and energy conservation issues in our peer selection and rate allocation schemes for multi-source streaming session.
  • Rate-Distortion Optimized Video Caching
    We revisit the video caching problem in wireless LAN environment and propose a data-selection strategy (i.e., which data units to cache) based on rate-distortion optimization framework.
  • Multi-Source Video Streaming Over Wireless LANs
    This work strives to combine the advantages of two communication modes offered by IEEE 802.11 networks: infrastructure and ad hoc modes. MINESTRONE enables a wireless client to selectively stream video contents from a joint sender group, composed by nearby wireless peers and potentially video server on the wired Internet. We formulate the streaming scheme as a combinational optimization problem and compare proxy vs. receiver-driven approach to the transmission scheduling problem.
  • Cross-layer Optimization for Multimedia Streaming over Internet
    This work examines how timely feedbacks from network layer can be exploited to optimize the design of source/channel coding and transmission schemes for multimedia streaming over the Internet, as well as wireless networks. Such cross-inspection of multiple layers (application, transport, network & data-link) is necessary to find vertically integrated solutions.
