Decentralized Auction-Based Bandwidth Allocation in a Wireless Networked Control Systems

Applications of control systems on wireless networks have been widely utilized due to their mobility. However, many Wireless Networked Control Systems (WNCS) may not cooperate with each other in order to share a limited amount of network bandwidth. Consequently, these agents may manipulate the resource in their own benefit and selfish behavior. Nevertheless, existing dynamic allocation methods may not lead to equilibrium of all network-based control system satisfactions. This paper presents a decentralized auction-based dynamic bandwidth allocation methodology based on mechanism design and game theory to allocate bandwidths of WNCS which enforces WNCS on the same network to request a bandwidth with actual requirement. The proposed mechanism results has proofed an actual bandwidth requirement is the dominant strategy and the exceed bandwidth requirement cannot provide the higher utility than the actual bandwidth requirement. The total utility is the solutions of maximized social welfare.
