چکیده
The increasing penetration of wearable and implantable devices necessitates energy-efficient robust ways connecting them to each other the cloud. However, wireless channel around human body poses unique challenges such as a high variable path-loss caused by frequent changes in relative node positions well surrounding environment. An adaptive area network (WBAN) scheme is presented that reconfigures learning from kinematics biosignals. It has very low overhead since these signals are already captured WBAN sensor nodes support their basic functionality. Periodic fluctuations activities like walking can be exploited reusing accelerometer data scheduling packet transmissions at optimal times. Network states predicted based on observed biosignals reconfigure parameters real time. A realistic emulator evaluates for everyday was developed assess efficacy proposed techniques. Simulation results show up 41% improvement delivery ratio (PDR) 27% reduction power consumption intelligent lower transmission levels. Moreover, experimental custom test-bed demonstrate an average PDR increase 20% 18% when using our EMG- heart-rate-based control methods, respectively. simulation code made publicly available https://github.com/a-moin/wban-pathloss.

Adaptive Sampling-Based Information Collection for Wireless Body Area Networks
To collect important health information, WBAN applications typically sense data at a high frequency. However, limited by the quality of wireless link, the uploading of sensed data has an upper frequency. To reduce upload frequency, most of the existing WBAN data collection approaches collect data with a tolerable error. These approaches can guarantee precision of the collected data, but they ar...
