PROJECT TITLE :

Distributed Data Traffic Scheduling With Awareness of Dynamics State in Cyber Physical Systems With Application in Smart Grid

ABSTRACT:

The design of communication infrastructure in cyber physical system (CPS) is of vital importance for proper operations of physical dynamics. In this paper, the scheduling of packet transmission over wireless communication networks in CPS is studied for the purpose of system state stabilization. To live the effective information quantity of different packets, the concept of virtual queue (VQ) is defined based on the delay-tolerant Kalman filtering. VQ-based back pressure algorithm is proposed for the distributed knowledge traffic scheduling. The impact of transmission delays on VQ lengths is additionally studied for the formulation of distributed scheduling strategy. The scheduling technique is then applied within the context of voltage management in microgrid and is demonstrated to achieve better performance than general scheduling algorithm while not the notice of dynamics state. More numerical simulations of information traffic scheduling considering transmission delay are carried out to demonstrate the validity of the scheduling algorithm, which is established consistent with VQ lengths plagued by transmission time delays.
