6LoWPAN Meeting66 IETF MontrealLow Power Mesh Networks


Low power mesh network

Low Power Mesh Network

  • Completely Battery Operated Networks

  • No mains/line powered devices

  • FFDs (routing devices) battery powered

  • All nodes can/will sleep


Application

Application

  • Interconnected smoke detectors

  • Tank level monitoring

  • Sensor nets with infrequent/event reporting

  • Temporary power outages


The issue

The Issue

  • Current Problem Document (requirements doc) aimed at hybrid networks

    • Line Powered FFDs with battery/line RFDs

  • Low Power Mesh networks may require specific mesh network layer support

    • Proactive vs Reactive routing

    • Table vivify

    • Entry timeouts

  • WG decision should take into account

  • Paragraph ChangeWhile some LoWPAN devices are expected to be extremely limited (the so-called "Reduced Function Devices" or RFDs), more capable "Full Function Devices" (FFDs) will also be present, albeit in much smaller numbers. FFDs will typically have more resources and be mains powered. Accordingly, FFDs will aid RFDs by providing functions such as network coordination, packet forwarding, interfacing with other types of networks, etc.While some LoWPAN devices are expected to be extremely limited (the so-called "Reduced Function Devices" or RFDs), more capable "Full Function Devices" (FFDs) will also be present, albeit in much smaller numbers.

  • Paragraph Addition (4.2 subparagraph 4)Support for network topologies that include both hybrid (combination of mains powered and battery operated) and battery operated networks with consideration for routing metrics, route maintenance and overhead and sleeping nodes.
