碩士 === 國立臺北科技大學 === 電子工程系研究所 === 104 === Internet of Things (IoT), in which massive things connect with other things and users, has become an important topic of new trends and technological development. We use ad-hoc mode for communication with other nodes and use wireless mesh- network technology to solve the regional coverage restrictions problem to reach the gateway for the Internet services. The popular mesh network node utilizes the best path among active links based on the optimized link state routing (OLSR) protocol. However, under a stable network, OLSR use lots of control packets to check the link status, which results in lower bandwidth usage. To solve this problem, we integrate OpenFlow technology and OLSR to collect network link status of the mesh topology based on the Open vSwitch standardized interface. Through the design of forwarding rules from the Open vSwitch to multiple gateways. We design and implement the Open vSwitch on the Raspberry PI to support wireless mesh network. The result shows that the network performance of Open vSwitch is not affected by the gateway failure condition.
