Popis: In this letter, we propose a binary integer linear programming (BILP) model of the problem of Energy Minimization under the constraint of Data Precision in the context of correlated data collection in wireless sensor networks, called EMDP. The exact solution of our BILP model determines, in each round of data collection, the role of each node in terms of sensing, data relaying, and processing. It gives the baseline for optimal network operations and helps characterizing the complexity of EMDP problem. Moreover, we propose a heuristic solution, namely, CORAD, which is an energy-aware correlation-based adaptive dynamic clustering algorithm for data collection.
