Center node: "networked computing in wireless sensor networks for structural health monitoring"
  Abstract: This paper studies the problem of distributed computation over a wireless network of resource constrained sensor#R##N#nodes. In particular, we focus our attention on sensor networks used for structural health monitoring. Within#R##N#this context, the heaviest computation is to determine the singular value decomposition (SVD) to extract mode#R##N#shapes (eigenvectors) of a structure. Compared to collecting raw vibration data and performing SVD at a#R##N#central location, computing SVD within the network can result in a significantly smaller energy consumption#R##N#and delay. Recent results have proposed methods to decompose SVD into components that can be carried out in#R##N#a distributed way. The focus of this paper is to determine a near-optimal communication structure that enables#R##N#the distribution of this computation and the reassembly of the final results, with the objective of minimizing#R##N#energy consumption subject to a computational delay constraint. We show that this reduces to a generalized#R##N#clustering problem; a cluster forms a unit on which a component of the overall computation is performed. We#R##N#establish that this problem is NP-hard. By relaxing the delay constraint, we derive a lower bound to this problem.#R##N#We also show that the optimal solution to the unconstrained problem has a simple structure that reveals insights#R##N#into the solution of the original constrained problem. We then propose an integer linear program (ILP) to solve#R##N#the constrained problem exactly as well as an approximate algorithm with a proven approximation ratio. We#R##N#also present a distributed version of the approximate algorithm. Numerical results are presented.
