Abstract
In this paper, we highlight considerations for synchronization issues in
body area networks. Requirements for the synchronization accuracy in
body area networks depend on the application at hand. Synchronization
may be needed for power management, sample ordering, calculation of
stimulus responses and for sensor fusion. This paper provides a
theoretical exercise to help understand the accuracy required for
typical human motion sensing. It gives an overview of various
synchronisation strategies used and implemented in prototype systems.
Lessons learnt from practical implementations using Bluetooth, an IEEE
802.15.4 proprietary network and Nanonet are presented to illustrate the
principles involved. The discussion provides some considerations and
the requirements for typical WBAN applications.
