Medium Access Control (MAC) Protocols for Ultra-Wideband (UWB)-Based Wireless Body Area Networks (WAN, a cross-layer solution is required. The physical layer of a WBAN determines the choice of wireless scheme, modulation scheme, synchronization and data rate. The data-link layer provides medium access control (MAC), which ensures reliable and fair access to the communication channel. Ultra-wideba

Antenna Diversity Techniques for Enhanced Ultra-Wideband Body-Centric Wireless Networks in Healthcat surge in interest in diversity-based techniques, whether it is from a spatial, frequency or polarisation perspective. In this chapter, studies for applicability of antenna diversity to be applied in ultra-wideband (UWB) on/off-body channel are carried out. Measurements are performed in both an ane
