Synchronized Communication in Low Power WBAN

Body Area Network (WBAN) requires efficient and innovative solutions for synchronized communication and to meet the energy consumption requirements for independent sensor nodes. In any wireless communication, the low message rate gives low power consumption but there is always a trade-off between power consumption and dynamic response. This paper presents the time synchronization methods and to develop a prototype to receive the time synchronized data in WBAN server from ANT wireless sensor nodes in SIGS system. The message rate used in SIGS is very low with 8 Hz, to consume less power. Hence it is essential to synchronize the system at low message rate. Whenever a data is received at WBAN / Linux server through ANT protocol, the received data is difficult to handle because of unknown sampling time. To overcome this problem and to receive time synchronized data, the new methods and prototype was designed. The time synchronization methods implemented provided good time synchronization for ANT low power wireless sensor network.
