In Wearable Well-Being project PUHVI, HipGuard system for patients recovering
from hip surgery was developed. Novel wireless sensors having 3-axis acceleration
and 3-axis magnetic sensors are used to measure patient’s hip and leg position and
rotation. Furthermore, capacitive insole sensors are used to measure the force
between foot and a shoe. This paper concentrates on how these sensors can be
interconnected to a central unit that collects and analyzes the measured information.
Body Area Network (BAN) utilized in wearable healtcare application have several
application-specific challenges such as low-power operation, low latency data
transfer, high system reliability and autonomous network operation. This paper
thoroughly analyzes how ANT wireless sensor networking technology operates as
BAN – the focus is mainly on energy efficiency, communication latency, network
size and reliability issues. Because the main focus of this paper is particularly in
the operability of ANT networking, these results can be directly utilized in many
other wireless sensor networking applications.
Keywords: body area networks, healthcare applications, wireless sensor networks.
Wireless sensor networks and sensors have
several application areas such as forest fire detection,
health monitoring, industrial sensing, and home
control. Sensor networks are based on physically
exchanging mainly measured
information. Sensors usually have very limited
power, processing, and memory resources and so
interactions between nodes are limited to short
distances and low data rates. Advances in electronics
have made these wireless sensor networks viable.
For example, sensors
