Introduction

• What is M2M ?
• M2M applications tend to use well-known
  communication technologies
• Lack of M2M standards regarding the data exchange
  (application layer)
• There exist a wide range of application layer
  protocols today

3
The research problem

• Which M2M related communication
• standards are applicable for M2M
• standardisation within the segments
• of Security, AMR and Utility Control
• ? Focus on standards which specifies how to
  transfer using IP

the same M2M solution, using only one
standard for server-to-gateway communication
23
Conclusions

• It is possible to create standardised M2M
  solutions based upon existing standards within
  the investigated segments
• Some can be used as is, while others need to be
  used in combination with another standard
• Utility Control and AMR has the largest number of
  suitable standards
• The security segment needs more standardisation
  work to support full featured M2M based solutions
