A robust and lightweight name resolution approach for IoT data in ICN

One discriminating characteristics of data in the Internet of Things (IoT) applications is that it may have multiple producers (e.g. many sensor devices deployed in an area to sense the same information). It is very important that the name resolution service is able to provide the proper producer selection based on client's criteria and the producers' contextual information. The paper proposes a robust and lightweight name resolution approach for IoT data in Information Centric Networking, which is considered to be one of the most promising architectures for future Internet as well as future IoT. The paper considers that each content has a Home Node, which acts as the only host virtually to the rest of the network. The paper discusses the procedures for Home Node adjustment due to the appearance of a new producer or disappearance of an existing producer. It also presents the solution for Home Node recovery when failure happens. The paper analyzes the advantages of the proposed approach, such as significantly less update message overhead, efficient storage usage and resilience to node failure.
