Scope of CMB Task GroupDraft an amendment of 802.15.4 for MBAN

This amendment defines a physical layer for IEEE Std. 802.15.4 utilizing the approved 174-216 MHz, 407-425 MHz and 608-630 MHz medical bands in China. This amendment defines modifications to the Medium Access Control (MAC) layer needed to support this new physical layer.

CMB Background

Wireless connectivity is already used for healthcare applications both within hospitals and in residential situations. This provides flexibility to clinicians and healthcare providers and mobility and convenience for the patients. Low Rate Wireless Personal Area Networks (LR-WPAN) are already widely being used for this. Applications include electrocardiography and the monitoring of pulse oximetry, blood pressure and glucose levels as well as other patient vital signs like respiration, heart rate and temperature. In China as in the US, LR-WPAN is part of the growing Internet of Things Industries; it has been applied in hospital areas for medical and related info communications.

IEEE Std. 802.15.4 Chinese medical devices will make use of the existing high volume applications in the Chinese medical bands.

IETF 6tisch Working Group Scope6tisch Goal: The 6tisch Working Group is focused upon enabling IPv6 over the TSCH mode of the IEEE802.15.4e standard. The extent of the problem space for the WG is one or more Low Power and Lossy Networks (LLNs), eventually federated through a common backbone link via one or more LLN Border Routers (LBRs).

Work Item 1: Produce "6TiSCH architecture" to describe the design of 6TiSCH networks. This document will highlight the different architectural blocks and signaling flows, including the operation of the network in the presence of multiple LBRs. Initially, the document will focus on distributed routing operation over a static TSCH schedule.

Work Item 2: Produce an Information Model containing the management requirements of a 6TiSCH node. This includes describing how an entity can manage the TSCH schedule on a 6TiSCH node, and query timeslot information from that node. A data model mapping for an existing protocol (such as Concise Binary Object Representation (CBOR) over the Constrained Application Protocol (CoAP)) will be provided.

Work Item 3: Produce "Minimal 6TiSCH Configuration" defining how to build a 6TiSCH network using the Routing Protocol for LLNs (RPL) and a static TSCH schedule. It is expected that RPL and the Objective Function 0 (OF0) will be reused as-is.

TSCH Overview(for more details see 15-11-484-03)

• Process Automation applications with a particular focus on equipment and process monitoring

• Operation– All devices in the same network synchronize slotframes– All timeslots are contained within a slotframe cycle– Timeslots repeat in time: the slotframe period– Device-to-device communication within a timeslot

includes packet Tx/Rx & ACK Tx/Rx

TSCH OverviewTypical application segments are:• Process automation facilities for the following:

– Oil and gas industry– Food and beverage products– Chemical products– Pharmaceutical products– Water/waste water treatments

•Automation Systems such as:– Smart grid networks– Lighting networks– Factory automation

TSCH OverviewThe TSCH mode uses time synchronized communication and channel hopping to provide network robustness through spectral and temporal redundancy.

Time slotted communication links increase potential throughput by minimizing unwanted collisions that can lead to catastrophic failure and provides deterministic, yet flexible, bandwidth for a wide variety of applications.

Channel hopping extends the effective range of communications by mitigating the effects of multipath fading and interference.

TSCH is also topology independent; it can be used to form any topology from a star to a full mesh.

TSCH MAC primitives can be used with higher layer networking protocols to form the basis of reliable, scalable, and flexible networks.

Submission

MAC behaviors unique to TSCH• The TSCH mode introduces no unique commands specific for

this mode; however, IEs are used extensively.• TSCH uses EBs containing the TSCH Synchronization payload

IE, TSCH-Slotframe and Link payload IE, TSCH Timeslot payload IE, and Channel Hopping payload IE to advertise the presence of a TSCH PAN and allow new devices to synchronize to it.

• Devices maintain synchronization by exchanging acknowledged frames within defined timeslot windows and providing timing corrections in the acknowledgment via the ACK/NACK Time Correction IE.

• Communication resources are broken up into timeslots that are organized into repeating slotframes

TSCH areas within the 802.15.4 rev draft

• TheTSCH-Slotframe structure behavior is cited in 5.2.7, PAN formation is cited in 5.3.6, synchronization is stated in 5.5.3, the IEs are described in 6.5.3.2, 6.5.3.3, 6.5.3.4, and the primitives are declared in 7.2.20.

TSCH link example for a 3-timeslot slotframe

Nodes A and B communicate during timeslot 0, nodes B and C communicate during timeslot 1, and timeslot 2 is not being used. Every three timeslots, the schedule repeats, but note that ASN increments continuously. The pairwise assignment of a directed communication between devices in a given timeslot on a given channelOffset is a link.

<July 2014>

Submission

Time Slotted Channel Hopping (TSCH)• Physical channel, CH, in a link is made according to

the following formula:– CH = macHoppingSequenceList [(macASN +

channelOffset) % macHoppingSequenceLength]

• Use of a channelOffset allows for different channels to be used at a given macASN for a given macHoppingSequenceList– There are macNumberOfChannels channel offsets that will

result in a unique channel for that combination of macASN and macHoppingSequenceList

TSCH Issues• Priorities

– Need a mechanism that gives priority for deterministic links such as PCA

• TSCH PIBs– Upper ranges (0xffff) for macTsMaxTx & macTsTimeslotLength are insufficient to

describe maximum values for sub GHz PHYs such as SUN; add another 4 bits

• Defaults– Default CCA values put 15.4 devices at a disadvantage in 2450 band when CCA mode 1

is used as per ETSI 300 328 v1.81; for CCA mode 1 use 20 μs, leave CCA mode 2 as is

– Defaults are not valid for 915 band; add defaults for each band (see slide 11)

– 6.5.3.4 – Add “All slotframes are referred to by an ID, macTimeslotTemplateId, with ID = 0x00 denoting the 2450 band default values and 0xf0 denoting the 915 band default values as per Table 139” (see slide 11)

• Editorial– 6.5.3.4 - Timeslot ID field should be set to the value of macTimeslotTemplateId

– Figure 147—add Ack Wait field before RXTX and after RX Wait

– 5.3.6 – correct the references in bulleted items

Summary• Roll-up of six PHY amendments show that many

amendments are using newly introduced behaviors from the MAC amendment such as enhanced beacons, information elements, enhanced acknowledgments

• TSCH, dominating industrial sensor networks, is the foundation used by the IETF 6tisch effort to standardize new higher layer protocols for many applications

• TSCH timings must change per band to accommodate data rates, regulatory, etc.

• Numerous mistakes in TSCH text must be corrected

Closing ReportThe IG 6T meeting was spent detailing the TSCH protocols and behaviors, taking special note of its use in industrial process automation applications.

Industrial standards that are based upon 802.15.4e’s TSCH are:•IEC62591 Wireless HART•IEC62601 WIA-PA•IEC62734 ISA100.11a

There were no questions or requests from the IG 6T attendees to be given to the IETF 6tisch WG at next week’s IETF 90 meeting in Toronto.

Chair expects that the IETF 6tisch WG will request new IEs be generated that would be appropriate to the TSCH mode within IEEE 802.15.4-2015
