In-Network-Processing: Distributed Consensus-Based Linear Estimation
In a cooperative broadcast scenario, a group of nodes in a network aims to reconstruct a common message. In this paper, the authors present a new algorithm for distributed consensus-based estimation in such scenarios. Possible applications comprise mobile communication systems and sensor networks. Starting with a least squares estimation problem, the algorithm is developed using techniques from optimization theory. The required communication effort for parallel implementation in a resource-constrained network is estimated and compared to existing approaches. They show that the proposed algorithm requires fewer iterations and a reduced communication overhead per iteration while keeping the estimation accuracy.
