Ambient Data Collection With Modeling and Implementation of QoS in Wireless Sensor Networks
One of the most important applications for Wireless Sensor Networks (WSNs) is Data Collection, where sensing data are collected at sensor nodes and forwarded to a central base station for further processing. Since using battery powers and wireless communications, sensor nodes can be very small and easily attached at specified locations without disturbing surrounding environments. This makes WSN a competitive approach for data collection comparing with its wired counterpart. With these features in mind, they then discuss issues and prior solutions on the data gathering protocol design.
