Adaptive Interest Lifetime in Named Data Networking to Support Disaster Area

Pending Interest Table (PIT) in Named Data Network (NDN) maintains a track of forwarded Interest packets so that the returned Data packet can be sent to its subscriber(s). PIT size is a crucial parameter, which can have a huge impact on the number of both satisfied and timed out Interest packet, and consequently, on the number of packet delay in terms of PIT overflow. There are a lot of studies focusing on caching, applications, and security to make NDN getting perfect, while the management of PIT is still one of the primary concerns of high-speed forwarding. Thus, PIT manages mechanism is one of the most important design specifics that have not been studied in the context of NDN to a significant extent. NDN needs to define concise mechanisms to monitor traffic when multiple users contend for access to the same or different resources, which may lead the PIT is overflowing and as a result increasing the delay. In order that, the objective of this study is to provide an adaptive mechanism under network load, namely Smart Threshold Interest Lifetime (STIL) to adjust incoming Interest packet in the early phase of occurrence to propose possible response decisions to realize PIT overflow recovery. The ndnSIM network simulator was used to measure the STIL. The results demonstrate that the proposed mechanism outperforms the performance of standard NDN PIT with respect to average Interest lifetime, Interest satisfaction, Interest retransmission and Interest satisfaction delay. The significance of this study is to provide a fundamental direction of a new adaptive Interest lifetime mechanism in NDN router to decrease the delay, especially on the natural disaster in a city, which will be very much useful for emergency operation centers, emergency rescue teams, and citizens

Review of name resolution and data routing for information centric networking

Information Centric Networking (ICN) a future Internet, presents a new paradigm by shifting the current network to the modern network protocols. Its goal, to improve the traditional network operations by enabling ICN packet routing and forwarding based on names.This shift will bring advantages, but at the same time, it is leading to a big challenge on routing approaches to implement ICN nodes. Routing approaches must use special techniques to publish messages to all the network nodes.Flooding approach is an easy and stateless, however, results in control overhead, depending on the network size.Moreover, designing, implementing, and evaluating routing approaches with higher capacity is really a key challenge in the overall ICN research area, because the state of ICN brings a significant cost; both in packet processing and router storage.Many approaches were proposed in the literatures over these years for the efficient control of forwarding on the network.This paper provides a classification and review of the routing mechanisms that are proposed on six ICN architectures.A summary in tabular form and a comparative study of these six architectures is also given in the paper as well as few open research challenges are highlighted
