Maximum precision‐lifetime curve for joint sensor selection and data routing in sensor networks
Kerem Bülbül, Özgür Erçetin · European Transactions on Telecommunications · 2007
Abstract In many classes of monitoring applications employing battery‐limited sensor networks, periodic sampling of an area with a given precision level is required. For such applications, we provide mathematical programming formulations for deriving the optimal trade‐off curve between network lifetime and data precision, and design a practical heuristic for near‐optimal operation. The properties of our models and the effectiveness of our heuristic are demonstrated by computational experiments. Copyright © 2007 John Wiley & Sons, Ltd.
