AB  - Data aggregation techniques exploit spatial and temporalcorrelations among data and aggregate data into a smallervolume as a means to optimize usage of limited network resourcesincluding energy. There is a trade-off among the Quality ofInformation (QoI) requirement and energy consumption for computationand communication. We formulate the energy-efficientdata aggregation problem as a non-linear optimization problemto optimize the trade-off and control the degree of informationreduction at each node subject to given QoI requirement. Usingthe theory of duality optimization, we prove that under a set ofreasonable cost assumptions, the optimal solution can be obtaineddespite non-convexity of the problem. Moreover, we propose adistributed, iterative algorithm that will converge to the optimalsolution. Extensive numerical results are presented to confirmthe validity of the proposed solution approach.
