CIDF-WSN: A Collaborative Interest and Data Forwarding Strategy for Named Data Wireless Sensor Networks.

Area of Science:

• Computer Science
• Networking
• Wireless Sensor Networks

Background:

• Information-Centric Networking (ICN), particularly Named Data Networking (NDN), is gaining popularity in Wireless Sensor Networks (WSNs).
• WSN nodes typically have a single radio interface, posing challenges for efficient data forwarding.
• Existing solutions struggle with optimal next-hop selection in NDN-based single-radio WSNs.

Purpose of the Study:

• To propose an efficient collaborative Interest and Data Forwarding (CIDF-WSN) strategy for Named Data Wireless Sensor Networks.
• To address the limitations of existing solutions in next-hop selection for single-radio WSNs.
• To enhance Interest and Data packet processing and forwarding mechanisms.

Main Methods:

• Development of a Neighbor Information Base (NFIB) for optimal next-hop relay selection during Interest packet forwarding.
• Implementation of an Interest Cache Table (ICT) to prevent Interest packet loss and re-transmissions.
• Introduction of a Temp Cache Table (TCT) for robust Data packet transfer, avoiding losses and ensuring timely delivery.

Main Results:

• The CIDF-WSN strategy demonstrates superior performance compared to recent published works.
• Significant improvements observed in Interest satisfaction rate.
• Reductions in total energy consumption, Data retrieval delays, and communication overhead.

Conclusions:

• CIDF-WSN effectively optimizes Interest and Data forwarding in NDN-based single-radio WSNs.
• The proposed strategy enhances network efficiency and reliability.
• The approach offers a promising solution for Named Data Wireless Sensor Networks.
