Wireless sensor networks are characterized by their low data rates, autonomous functioning and longevity. Low power consumption in such energy-constrained networks is a central issue and we target this design parameter by proposing and implementing a novel Cell-based Distributed Addressing Technique (C-DAT) over a k-power level sensor network. This paper introduces a clustered backbone approach for data forwarding and shows how data aggregation can be achieved, by implementing a MIN query over the network. The proposed scheme is evaluated for power consumption during addressing and various network dynamics using a java based network simulator. Results obtained highlight some key variable power-level model parameters and power consumption trends.
