The main objective of this work is distributed state estimation in wireless sensor networks (WSNs). We assume that some sensors forming a connected network topology are deployed in a space to measure state variables in a common modeled process (e.g. a rotating object or a moving car). The most famous state estimation approach is called Kalman filter (KF). To avoid the centralized signal processing, there is no central node in our scenario. Each node will estimate the state variables distributedly based on its local knowledge and information from neighbors. Hence, a distributed Kalman filter (DKF) algorithm should be further investigated. 

In this project, the student will focus on a distributed Kalman filtering method using diffusion strategies [1]. According to the literature, an analysis on the performance of the algorithm should be studied. MATLAB simulations regarding to diffusion DKF compared with other DKF algorithms [2] also needs to be done.
