Hierarchical Name-Based Mechanism for Push-Data Broadcast Control in Information-Centric Multihop Wireless Networks

Area of Science:

• Computer Science
• Networking
• Internet of Things (IoT)

Background:

• Named Data Networking (NDN) primarily supports pull-based content retrieval.
• Internet of Things (IoT) applications, especially in emergencies, require push-based data dissemination.
• Existing NDN solutions for IoT push traffic lack robust broadcast control and introduce network overhead.

Purpose of the Study:

• To propose a novel name-based push-data broadcast control scheme for IoT systems.
• To address the limitations of current solutions regarding broadcast control and network overhead.
• To evaluate the scheme's performance in smart building and vehicular network scenarios.

Main Methods:

• Developed a name-based push-data broadcast control scheme.
• Incorporated robust content and device namespace designs.
• Modified NDN data packet format and unsolicited data policies.
• Evaluated the scheme through simulations in smart buildings and vehicular networks.

Main Results:

• The proposed scheme significantly reduces the total number of data packets processed in the network.
• Demonstrated lower total energy consumption compared to existing methods.
• Achieved a notable reduction in average network delay.
• Performance improvements were consistent across varying data packet rates and vehicle speeds.

Conclusions:

• The name-based push-data broadcast control scheme effectively enables efficient push-based traffic in NDN for IoT.
• The proposed scheme offers a superior alternative to existing solutions by minimizing network overhead and enhancing performance.
• The design is adaptable for diverse IoT environments, including smart buildings and vehicular networks.
