Abstract: The present invention pertains to a method for providing synchronization between a plurality of wireless body sensors, the method comprising: establishing (1010) a time schedule designating different individual sensors of said plurality of wireless body sensors as a master node for respective consecutive periods of time; operating (1020) said plurality of wireless body sensors whereby said different individual sensors broadcast a periodically repeated synchronization signal during said respective consecutive periods of time; analyzing (1030) an energy consumption and performance pattern of said plurality of wireless body sensors under said time schedule; and updating (1040) said time schedule on the basis of said energy consumption and performance pattern. The invention also pertains to a method for operating a synchronized network of wireless body sensors, a wireless body sensor, a scheduler, and a monitoring system.
