Wireless Sensor Networks: Distributed Consensus Estimation

This SpringerBrief evaluates the cooperative effort of sensor nodes to accomplish high—level tasks with sensing, data processing and communication. The metrics of network—wide convergence, unbiasedness, consistency and optimality are discussed through network topology, distributed estimation algorithms and consensus strategy. Systematic analysis reveals that proper deployment of sensor nodes and a small number of low—cost relays (without sensing function) can speed up the information fusion...
