Interference Management and Rate Adaptation in OFDM-Based UWB Networks
—Ultra-wideband (UWB) communications has emerged as a promising technology for high data rate wireless personal area networks (WPANs). Several proposals for UWB-based WPANs have ...

The optimal MAC layer for low-power UWB is non-coordinated
— We consider the design of the MAC layer for low power, low data-rate, impulse-radio ultra-wide band (IRUWB) networks. In such networks, the primary concern is energy consumptio...

A Polynomial-Time Approximation Algorithm for Weighted Sum-Rate Maximization in UWB Networks
— Scheduling in an ad hoc wireless network suffers from the non-convexity of the cost function, caused by the interference between communication links. In previous optimization t...

A Rate-Adaptive MAC Protocol for Low-Power Ultra-Wide Band Ad-Hoc Networks
Recent theoretical results show that it is optimal to allow interfering sources to transmit simultaneously as long as they are outside a well-defined exclusion region around a de...

Effective Packet Scheduling with Fairness Adaptation in Ultra Wideband Wireless Networks
Abstract— The inherent spread spectrum nature in ultrawideband (UWB) communications can support simultaneous transmissions. Two nearby transmissions do not collide, but rather ge...
