Body Sensor Networks (BSNs) and WiFi networks have been widely investigated due to the availability of sensor motes and WiFi devices, but they are commonly deployed separately. In this paper, the authors propose to optimize the total communication energy consumption of BSN and WiFi (BSN-WiFi) networks using joint data rate adaptation. More specifically, they first elaborate the BSN-WiFi network system in four consecutive phases. Then based on the system, they analyze the communication energy consumption, throughput and time delay, and provide a Signal-to-Noise Ratio and Packet Delivery Ratio (SNR-PDR) mappings of BSN and WiFi networks.
