In large wireless sensor networks, the few nodes close to the monitoring station are likely to prove the bottleneck in the useful lifetime of the network. We examine a strategy of equipping these nodes with a larger share of the total initial energy (battery) than the others, and generalizing this notion to the rest of the network. We solve a design problem involving optimizing the network lifetime using no more than a given number of distinct battery levels, and verify the results from the model by direct simulation. © IFIP International Federation for Information Processing 2005.
