“…But, on the other hand, it may increase the time needed for device discovery. Therefore we introduced a RSW adaptation algorithm in the TCDD protocol, which is similar with the SDD protocol [5]. Based on the previously proposed analytical model in [8], we investigate the relations among the factors impacting the RSW receptions.…”

Abstract-Ultra Wide Band (UWB) has recently gained great interest for high data rate short-range WPANs. Designing a MAC protocol for UWB WPANs must take into account the physical layer characteristics. Due to large bandwidth and spreading spectrum, a time hopping impulse radio UWB (IR-UWB) system can accomplish multiple access by using code division multiplexing. Unlike most existing MAC protocols relying on contention access to limit transmissions, the MAC design for impulse radio intends to accommodate simultaneous transmissions. In this paper, we newly propose a MAC scheme for IR-UWB WPANs. This scheme is a hybrid CDMA and TDMA approach based on time hopping spread spectrum and the timing format of IEEE 802.15.3 MAC. The simulation results show that the proposed approach outperforms the existing protocol under our specifications and WPAN scenarios.

The Self-organizing Device discovery and Data transmission protocol (SDD) is a novel self-organizing link layer protocol, that was proposed for UWB impulse radio based networks. By means of simulations, it has been indicated that the SDD protocol enables a node to discover most of its neighboring nodes in short discovery time, in the mean time, appropriately avoids collisions. Further evaluations are carried out in this paper by creating a new analytical model to investigate the theoretical relations among the discovery time, the discovery ratio and the system parameters. It can be concluded that the SDD protocol is an efficient, scalable and well performed protocol.
