Wireless Sensor Networks (WSNs) are increasingly used in data-intensive applications such as microclimate monitoring, precision agriculture, and audio/video surveillance. A key challenge faced by data-intensive WSNs is to transmit all the data generated within an application's lifetime to the base station despite the fact that sensor nodes have limited power supplies. The authors propose using low cost disposable mobile relays as doze nodes to reduce the energy consumption of data-intensive WSNs. Their approach differs from previous work in one main aspect. Mobile relay does not actively forward data from source node to base station but continues to listen to the source nodes and monitors the signal level around it.
