Dynamic Resource Allocation of Gateways for Packet Transmission in Cyber-Physical Systems

Cyber-Physical System is an integration of physical world and digital world, and widely used by industries and daily life. With the development of wireless communication technology, different wireless technologies suitable for variety situations have been adopted by Cyber-Physical System. It is ubiquitous that equipment with different types of wireless technologies cooperates with each other. We call the wireless network composed of different wireless communication technologies the hybrid wireless communication network. Devices with different kinds of wireless technologies cannot communicate with each other directly, so gateways are needed. In this paper, we propose a dynamic gateway bandwidth allocation algorithm, in order to improve the performance of hybrid wireless network. Simulation results have shown that this algorithm leads to excellent performance.
