Recently sink mobility has been exploited in numerous schemes to prolong the lifetime of
wireless sensor networks (WSNs). Contrary to traditional WSNs where sensory data from …

In this paper, we propose a new data-gathering mechanism for large-scale wireless sensor
networks by introducing mobility into the network. A mobile data collector, for convenience …

Many emerging location-aware applications require position information. However, these
applications rarely use celltower-based localization because of its inaccuracy, preferring …

Wireless Sensor Networks with Mobile Sinks (WSN-MSs) are considered a viable alternative
to the heavy cost of deployment of traditional wireless sensing infrastructures at scale …

We study the ubiquitous data collection for mobile users in wireless sensor networks. People
with handheld devices can easily interact with the network and collect data. We propose a …

In this paper, a protocol called Energy Efficient and QoS aware Routing (EEQR) protocol for
Clustered Wireless Sensor Network is proposed. To ensure QoS for different traffic types …

ZigBee is a specification formalized by the IEEE 802.15. 4 standard for low-power low-cost
low-data-rate wireless personal area networks. In ZigBee networks, a tree topology is often …

We study the ubiquitous data collection for mobile users in wireless sensor networks. People
with handheld devices can easily interact with the network and collect data. We propose a …

The Internet of Things (IoT) enables environmental monitoring by collecting data from
sensing devices, including cameras and microphones. The popularity of smartphones …

In this paper we have proposed and designed FindingHuMo (Finding Human Motion), a real-
time user tracking system for Smart Environments. FindingHuMo can perform device-free …
