The IEEE 802.15.3 is a High Rate (HR) Wireless Personal Area Network (WPAN) standard, which is standardised by IEEE in 2003. This standard is· MACIPHY specifications for wireless connections ofpersonal devices. This thesis proposes enhancements for the HR WPAN standard including the Piconet Coordinator (PNC) selection criteria and power management. The following topics have been studied, analysed, simulated and presented in this thesis: 1. Piconet Coordinator Selection Criteria 2. User Centricity in WPAN using the Personal Identification Device (PID) 3. User Detection (using the PID) 4. WPAN Routing Due to the vital functionality of the PNC in the WPAN, the most capable device in the WPAN is selected as the PNC. The original WPAN standard has presented a set of PNC criteria based on the PNC candidate potential capabilities such as the maximum transmitter power and the maximum association requests the device can handle. The proposed criteria are based on the actual PNC capabilities such as the number of devices directly connected to the PNC candidate. The proposed criteria extension field is designed and integrated within the standard model. The simulation results have proven that the WPAN functionality is improved when the proposed PNC criteria are applied compared to the original criteria. The concepts of user-centricity and user detection have been introduced to the WPAN in order to improve the network friendly-use and to enhance the standard security and data protection. According to the proposed PID design, the network detects the user vicinity and is activated automatically accordingly. The network activity is based on the user location and it follows the nearest device used by the network owner. This is a new feature that is added to the original WPAN standard. Finally, the WPAN routing issue has been studied and analysed. Mathematical model has been designed and analysed for piconet coverage. Accordingly, a new routing approach has been proposed based on the PNC enhancement for routing information.
