Node Deployment for Distributed Consensus Estimation

This chapter deals with node deployment problem for distributed estimation of unknown signals in relay assisted WSNs. It is discovered that the network topology is closely related to the properties of the estimation algorithm. To satisfy the performance of the estimation algorithm, two node deployment algorithms are given. The first is concerned with the connectivity of network topology and the second illustrates a greedy approach to further optimize the network topology and the parameters of the estimation algorithms. Simulation results are provided to demonstrate the performance and effectiveness of the node deployment algorithms for solving distributed estimation problems in relay assisted WSNs.
