M2M Work Item

DTR/M2M-00014– Start of work April ’11

– Target completion of work October ’11

– Status – draft, WIP

– Scope• Study the interworking between M2M Area Network technologies and the ETSI M2M architecture


• Study the interworking between M2M Area Network technologies and the ETSI M2M architecture

– Objectives• Study how the functional elements of M2M Area Network technologies map to the M2M architecture

• Identify possible optimizations of the M2M architecture to accommodate unique aspects of M2M Area Network technologies

• Identify potential limitations of M2M Area Network technologies to be reported to the relevant organisation

What does a ZigBee Network do?

How ZigBee Devices work– Authenticate to join a network

– Associate with a Controller

– Establish secure relationship – Trust Centre

– Register to receive messages

– Then, basically, sleep…

Conclusions

ZigBee products form a rich domain of M2M Area Network devices and applications

TR 102 966 provides an efficient and fully functional mapping between ZigBee objects, commands & attributes to M2M resources

ZigBee Gateway specification aligns with M2M interface philosophy


philosophy

ZigBee devices & networks can be dynamically added to the M2M domain

Redirection and mirrored resources allow energy efficient operation of ZigBee devices

Services can be provided independent of ZigBee device location

Go and play with the demonstration!
