Transmission power control can significantly improve energy-efficiency of wireless sensor network communications. Power consumption models are typically based on dependence of channel attenuation on distance. However, in practice, information on distance is usually not available and the dependence of channel attenuation on distance is not sufficiently accurate. Therefore, we propose more accurate...
In this paper, an analytical power consumption model for beacon-mode and CSMA/CA-mode access schemes is developed for a wireless body area network (WBAN). Apart from considering the conventional collision from intra-network nodes, the model also investigates the collision caused by the nodes from different moving WBAN groups. From the analysis, we will identify the need of having a hybrid-mode access...
