Low Latency Wireless Networks for Mission Critical Communications

Increasingly wireless data services extend beyond traditional best-effort communication to enhanced data applications such as interactive video, real-time multimedia streaming, high-throughput data access and Voice-over-IP. Additionally, the United States military greatly relies on wireless communications for its operations,including command, control, surveillance, reconnaissance, and targeting system. Invariably, meeting the quality-of-service (QoS) requirements of these applications translates into strict delay and throughput constraints. However,meeting such requirements over an unreliable wireless channel is a very challenging task, due to mobility, time varying channel quality, energy and power limitations, and packet losses. Our goal is to develop transmission scheduling schemes for traffic with both latency and throughput requirements.
