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. We explore the fundamental limits of energy-efficient collaborative data-gathering by deriving upper bounds on the lifetime of increasingly sophisticated sensor networks.
