Abstract EN
Network virtualization has become pervasive and is used in many applications.
Through the combination of network virtualization and wireless sensor networks, it can greatly improve the multiple applications of traditional wireless sensor networks.
However, because of the dynamic reconfiguration of topologies in the physical layer of virtualized sensor networks (VSNs), it requires a mechanism to guarantee the accuracy of estimate values by sensors.
In this paper, we focus on the distributed Kalman filter algorithm with dynamic topologies to support this requirement.
As one strategy of distributed Kalman filter algorithms, diffusion Kalman filter algorithm has a better performance on the state estimation.
However, the existing diffusion Kalman filter algorithms all focus on the fixed topologies.
Considering the dynamic topologies in the physical layer of VSNs mentioned above, we present a diffusion Kalman filter algorithm with dynamic topologies (DKFdt).
Then, we emphatically derive the theoretical expressions of the mean and mean-square performance.
From the expressions, the feasibility of the algorithm is verified.
Finally, simulations confirm that the proposed algorithm achieves a greatly improved performance as compared with a noncooperative manner.
