Forwarding techniques for IP fragmented packets in a real 6LoWPAN network

Area of Science:

• Computer Science
• Networking
• Wireless Sensor Networks

Background:

• Wireless Sensor Networks (WSNs) offer low-cost solutions for large-scale deployments.
• Interoperability with IP networks is crucial for WSN adoption.
• The 6LoWPAN protocol stack enables IPv6 transmission over IEEE 802.15.4 WSNs.

Purpose of the Study:

• To analyze different 6LoWPAN routing solutions (mesh under, route over, enhanced route over) focusing on fragment forwarding.
• To evaluate the performance of these routing solutions in terms of latency and energy consumption.
• To propose and analyze a novel 'controlled mesh under' routing scheme.

Main Methods:

• Analysis of existing 6LoWPAN routing strategies: mesh under and route over.
• Performance evaluation using a real-world 6LoWPAN implementation.
• Development and analysis of a new 'controlled mesh under' routing scheme.

Main Results:

• Evaluation of latency and energy consumption for different routing approaches when transmitting IP fragmented packets.
• Identification of key challenges in mesh frame forwarding within WSNs.
• Performance analysis of the proposed 'controlled mesh under' scheme.

Conclusions:

• The study provides insights into the performance trade-offs of 6LoWPAN routing protocols concerning fragment handling.
• A new 'controlled mesh under' routing scheme is presented as a potential improvement for WSNs.
• The research contributes to optimizing WSN interoperability and efficiency.
