The Internet protocol (IP) is now embedded into sensor-and-actuator nodes these days, rising the new age of full IP sensor-actuator networks. Though we can make them available on the Internet space with such embedded TCP/IP stacks, the appropriate link-layer media for networking them in facilities are not Ethernet. In stead, it is considered to be IEEE802.15.4 and RS485, which are known as lossy, unstable and narrow link media. This sometimes cause fatal problems especially traffic congestion at the router of connecting such narrow link in some application senarios. This paper proposes the architecture and design of In-Network Traffic Control (InNetTC) scheme that solves this issue. We carried out experiments with the prototype of InNetTC-enabled router. The result shows that InNetTC achieved 100% success of task execution for such application scenarios, indicating that InNetTC plays an important role for implementing applications on such full IP sensor-actuator networks.
