Introduction

Intoduction

DEFINITION BY IEEE: A communication standardOptimized for low power device for their operation On , inand around the human body to serve a variety ofapplications including medical , consumer electronics orpersonal entertainment and other.[4]

Standardization of WBAN : IEEE 802.15.6[7][4]

Introduction

Wireless Body Area Network

WBAN is a network around the human body.

It allows the integration of intelligent, miniaturized, lowpower sensor node in, on or around a human body tomonitoring body function.[1]

It senses biological, physical, chemical changes of ourbody and alarms the person who wears it.[4]

It helps in auto medication in case of emergency

Layers of WBANS

Layers of WBANS

Physical Layer : The PHY layer of IEEE 802.15.6 isresponsible for the following tasks[4][3];

1 Activation and deactivation of the radio transceiver2 Clear channel assessment (CCA) within the current

channel3 Data transmission and reception.

MAC Layer : The IEEE 802.15.6 working group defines tocontrol channel access[4][3].The hub (or coordinator) divides the entire channel (ortime axis) into a chain of superframes for timereferenced resource allocations. The hub also choosesbeacon periods of equal length to bound thesuperframes.
