Motes are only active in time slots where they are scheduled to transmit or receive, typically resulting in a duty cycle of < 1%. The optimization soft-ware in the Network Manager coordinates this schedule automatically.

5 When combined with the Eterna low power radio, every mote in a SmartMesh network even busy routing ones can run on batteries for years. By default, all motes in a network are capable of routing traffic from other motes, which simplifies installation by avoiding the complexity of having distinct routers vs non-routing end nodes. Motes may be configured as non-routing to further reduce that particular mote s power consumption and to support a wide variety of network SmartMesh network consists of a self-forming multi-hop mesh of nodes, known as motes, which collect and relay data, and a network manager that monitors and manages network performance and security, and exchanges data with a host application. SmartMesh networks communicate using a time slotted channel hopping (TSCH) link layer, pioneered by Dust Networks. In a TSCH network, all motes in the network are synchronized to within less than a millisecond. Time in the network is organized into time slots, which enables collision-free packet exchange and per-transmission channel-hopping.

6 In a SmartMesh network, every device has one or more parents ( mote 3 has motes 1 and 2 as parents) that provide redundant paths to overcome communications interruption due to interference, physical obstruction or multi-path fading. If a packet transmission fails on one path, the next retransmission may try on a different path and different RF channel. A network begins to form when the network manager instructs its on-board Access Point (AP) radio to begin sending advertisements packets that contain information that enables a device to synchronize to the network and request to join. This message exchange is part of the secu-rity handshake that establishes encrypted communications between the manager or application, and mote. Once motes have joined the network, they maintain synchronization through time corrections when a packet is the heart of SmartMesh motes and network manag-ers is the Eterna IEEE System-on-Chip (SoC), featuring Dust Networks highly integrated, low power radio design, plus an ARM Cortex-M3 32-bit micropro-cessor running SmartMesh networking software.

7 The SmartMesh networking software comes fully compiled yet is configurable via a rich set of Application Program-ming Interfaces (APIs) which allows a host application to interact with the network, to transfer information to a device, to configure data publishing rates on one or more motes, or to monitor network state or performance metrics. Data publishing can be uniform or different for each device, with motes being able to publish infrequently or faster than once per second as ongoing discovery process ensures that the network continually discovers new paths as the RF conditions change. In addition, each mote in the network tracks per-formance statistics ( quality of used paths, and lists of potential paths) and periodically sends that information to the network manager in packets called health reports.
