Abstract
Disasters are the uncertain calamities which within no time can change the situation quite drastically. They not only affect the system’s infrastructure but can also put an adverse effect on human life. A large chunk of the IP-based Internet of Things (IoT) schemes tackle disasters such as fire, earthquake, and flood. Moreover, recently proposed Named Data Networking (NDN) architecture exhibited promising results for IoT as compare to IP-based approaches. Therefore to tackle disaster management system (DMS), it is needed to explore it through NDN architecture and this is the main motivation behind this work. In this research, a NDN based IoT-DMS (fire disaster) architecture is proposed, named as NDN-DISCA. In NDN-DISCA, NDN producer pushes emergency content towards nearby consumers. To provide push support, Beacon Alert Message (BAM) is created using fixed sequence number. NDN-DISCA is simulated in ndnSIM considering the disaster scenario of IoT-based smart campus (SC). From results, it is found that NDN-DISCA exhibits minimal delay and improved throughput when compared to the legacy NDN and existing PUSH schemes.
Highlights
The Internet of Things (IoT) aims to provide promising connectivity solutions across the globe.IoT plays a vital role for communication among the homogeneous and the heterogeneous devices required to control and monitor these devices
In order to calculate the robustness of the system we are using the Average Delay (AD) (Time metric) parameter that calculates the overall delay between two nodes and to calculate the effectiveness of the system, we are using the Average Throughput (ATH) (Rate Metric) that calculates the overall bit rate inside the data structure of Named Data Networking (NDN) node on the basis of cache hit or cache miss
We propose an NDN-DISCA by enabling push support on the fixed seq no
Summary
The Internet of Things (IoT) aims to provide promising connectivity solutions across the globe. ICN-based architectures ( Name Data Networking (NDN)) have interest and data messages that smart (networked) devices can use to inquire and get a response from the IoT network [22]. In IoT-based DMS scenario which has smart gadgets with limited memory and power, it is not feasible to perform push transmission through these existing schemes. In our NDN-IoT based DMS scheme, we propose a lighter version of PUSH support to incorporate above-mentioned issues (of throughput and delay) through generation of synthetic interest based BAM. We propose a lighter version for PUSH support on the basis of beacon message (BAM) for DMS in an IoT scenario SC, which is more robust and effective than the schemes which are mentioned in [23,26].
