Abstract:
hen it comes to deploying large scale, low power wireless networks comprising battery-operated embedded systems or motes, frequent replacement of batteries is undesirable. This motivates estimating the energy consumption in wireless motes accurately prior to deployment, and would avoid ``sudden" decreased network coverage owing to pre-mature mote deaths. Using our proposed model, the energy consumption in the PHY layer was found to be within 10-15% of the actual value obtained using measurements, and corresponded to an accuracy of 2-10% in the mote life. Furthermore, the cross-layer energy profiling involving the MAC layer provided insights into the energy consumed during the key modes of a simple, practical MAC protocol. To summarize, the primary purpose of this paper is to profile the energy consumption in a mote using a novel ``off-line" model to predict its operation life with high accuracy.
