Wireless Sensor Networks (WSNs) have emerged as an effective solution for a wide range of applications. Most of the traditional WSN architectures consist of static nodes which are densely deployed over a sensing area. The authors introduce a new data-gathering mechanism for large-scale wireless sensor networks by introducing mobility into the network. An M-collector (Mobile data collector) starts the data-gathering tour periodically from the static data sink, polls each sensor while traversing its transmission range, then directly collects data from the sensor in single-hop communications, and finally transports the data to the static sink.
