Leveraging Named Data Networking For Fragmented Networks in Smart Metropolitan Cities

초록

A fragmented network is a phenomenon caused when a metropolitan area network is affected due to some natural calamities such as fire, earthquake, flood, and so on. A reliable communication among nodes in the fragmented network is a vital research issue. Different solutions have been proposed to establish communications among nodes in such a fragmented network. One such solution is to make the use of named data networking (NDN). The NDN with the help of content store, pending interest table, and forwarding information base, establishes the communication with other nodes based on the names of contents, rather than the nodes themselves. However, these solutions are inefficient in the case of fragmented networks. In this research, we propose an NDN-based technique which uses the satisfied interest table (SIT) along with the push-based special alert message to communicate with other nodes to overcome such issues. We also use the Nonce phenomena to avoid loops during communications. The use of SIT helps a node to find the relative information quickly in the fragmented networks. By using this technique along with the SAM, we achieved better efficiency and response time.
