CS-Man: computation service management for IoT in-network processing.

Abstract

The Internet of Things (IoT) expects to link billions of devices to the Internet, which will produce massive amounts of data. Current approaches move the IoT data out of the network for processing. It results in long delays and increases the network traffic. The Named Function Networking (NFN) proposes a generic computation architecture for in-network data processing. But it does not consider a scheduling scheme or provide details of how to deploy services. This paper designs a computation service management (CS-Man) protocol by utilizing the NFN concept to assign and schedule computation tasks within IoT network. It is implemented by two procedures: service discovery and service deployment. Thus, the whole network is capable of assigning an advanced task to the specific node as well as fetching necessary pieces required by that task. Experiments including five use cases have been done to prove the feasibility of CS-Man. It also lowers the network traffic approximately by four times when compared with the out-of-network processing method.
