In the IEEE 802.15.3-based HR-WPAN(High Rate Wireless Personal Area Networks), the selection of PNC is based on the capability of each DEV in the piconet. The selected DEV playing the role of a PNC will consume the most amount of energy among the DEVs in the piconet. Since the energy consumption of the PNC is closely related to its frame transmission range in the piconet, it is important to consider the relative location of each DEV when selecting the PNC among DEVs. In this paper, we propose a novel approach to the PNC selection procedure in the piconet that attempts to position the PNC at the center of the topology. By doing so, it can minimize the total transmission distances from the PNC to all other DEVs, resulting in saving energy for the PNC and therefore extending the life-time of the PNC as well as the piconet. We describe our method in detail and present experimental results that show the significant improvement in the energy saving. © IFIP International Federation for Information Processing 2006.
