Abstract
A key challenge in ad-hoc, data-gathering wireless sensor networks is achieving a lifetime of several years using nodes that carry merely hundreds of joules of stored energy. In this pa- per, we explore the fundamental limits of energy-efficient collabo- rative data-gathering by deriving upper bounds on the lifetime of increasingly sophisticated sensor networks.Keywords
