An Efficient Low-Power MAC Protocol for Wireless Body Sensor Networks

Abstract

The battery of a sensor node in a wireless body sensor network is small, and therefore has a short lifetime.

Wireless body area networks (WBANs) are a fascinating research field offering wearable and implantable sensor technology [1][2][3][4][5][6][7][8][9][10][11][12][13], communications and platforms [14][15][16][17][18][19][20][21] that are revolutionizing healthcare, quality of life and interactions between physicians and patients. A WBAN is realized through the integration of different nodes (sensors and actuators) relying on different communication technologies (wired, wireless and human body communication [22][23][24][25][26][27][28][29][30]) to allow interconnection under skin, over skin, when embedded in clothes and in portable devices, to provide both managed and autonomous applications [31][32][33][34][35][36].
