ABSTRACT

Ultra-wideband (UWB) is a promising technology for short-range bandwidth-demanding wireless communications. Several portable devices equipped with UWB transceivers can autonomously form a so-called wireless personal area network (WPAN) to conveniently exchange bulky data or high-quality multimedia streams. Because the wireless medium is shared by multiple users with different quality-of-service (QoS) requirements, fulfilling the diverse needs of user applications and achieving efficient utilization of the scarce wireless resource are important and challenging issues. This chapter is devoted to effective resource allocation for UWB-basedWPAN.We start by identifying the deficiency of the existing scheduling mechanisms when they are applied to UWB networks, mainly because they do not take UWB specific features into account. By coupling the physical characteristics of UWB with the resource allocation process, we propose practical scheduling algorithms for different design objectives, namely throughput maximization for homogeneous traffic and QoS provisioning for heterogeneous traffic, respectively. Simulations are used to demonstrate the effectiveness and efficiency of the proposed algorithms.
