Routing Technical challenges in LLNs<br />
• Energy consumption is a major issue (for battery powered<br />
sensors/controllers),<br />
• Limited processing power<br />
• Very dynamic topologies:<br />
• Link failure (LP RF)<br />
• Node failures (triggered or non triggered)<br />
• Node mobility (in some environments),<br />
• Data processing usually required on the node itself,<br />
• Sometimes deployed in harsh environments (e.g. Industrial),<br />
• Potentially deployed at very large scale,<br />
• Must be self-managed (auto-discovery, self-organizing<br />
networks)<br />
