Recent advances in pedestrian navigation, a branch of wearable body area networks (WBAN), facilitate people's lives to help them get access to location-based services (LBS) at anywhere easily. This paper proposes a pedestrian dead-reckoning (PDR) algorithm to track the trajectory of the person using foot-mounted inertial measurement unit (IMU) and the estimation of the foot orientation with extended...
Emergency management systems (EMS) are important and complex examples of Cyber-Physical-Human systems that are deployed so as to optimise the outcome of an emergency from a human perspective. They use sensor networks, networked decision nodes and communications with evacuees and first responders to optimise the overall Quality of Service to benefit primarily human beings in terms of survival, health...
In this paper, we present a dynamic navigation algorithm (DNA) that can be combined with GPS receivers, digital maps, and wireless technologies such as DSRC, 802.11p, and WiMAX. By calculating the score, a weighted sum of average vehicle speed, average inter-vehicle distance, road type, and road gain, for each candidate road, the DNA can generate a road score table and choose the road with the highest...
An inherent concern for a wireless sensor network (WSN) is the unbalanced energy consumption problem, where sensors closer to the sink are more likely to exhaust their energy faster than other nodes. To mitigate this problem, this paper considers including some resource-rich mobile nodes, called mobile data-pumps, to conduct data relaying from static sensors to the sink. The network thus becomes a...
