Abstract--In this paper, we combine inertial sensing and sensor
network technology to create a pedestrian dead reckoning system.
The core of the system is a lightweight sensor-and-wireless-em-
bedded device called NavMote that is carried by a pedestrian. The
NavMote gathers information about pedestrian motion from an
integrated magnetic compass and accelerometers. When the Nav-
Mote comes within range of a sensor network (composed of Net-
Motes), it downloads the compressed data to the network. The net-
work relays the data via a RelayMote to an information center
where the data are processed into an estimate of the pedestrian
trajectory based on a dead reckoning algorithm. System details
including the NavMote hardware/software, sensor network mid-
dleware services, and the dead reckoning algorithm are provided.
In particular, simple but effective step detection and step length
