14. The Data Processor
• Equipped with functions for communicating with other
objects of the mobile terminal. The data processor can
read/write data from/to web pages and sensors/actuators
using these functions.
• Equipped with table manipulation functions such like
– sumif, countif
of Excel

15. The Data Processor

Some of Embedded
Functions
• Extracting result part in the Wiki page
getResultPart(<page>)

17. The Data Processor
Some of Embedded
Functions
• Parsing CSV and translating the value into an array
parseCsv(<csv>,<dataTable>,
<rowLabel>,<columnLabel>)

18. The Data Processor
Some of Embedded
Functions
• <csv>

19. The Data Processor
Some of Embedded
Functions
• <rowLabel> is the hash table
– (“rowcol”, “row”)
– (“maxIndex”, maximum row index of the table).
• <columnLabel> is the hash table
– (“rowcol”,”col”),
– (“maxIndex”, maximum column index of the table),
– (<col-label-1>, column index of the label), …, (<col-label-max>).

43. Comparisons with Related
Work
• Xively (COSM)
– Xively is a real-time open data web service for the Internet of
Things.
– has open APIs for uploading and manipulating data
– Our M2M system has functions similar to those of Xively.
– the APIs of Xively are used for the Xively site only.
– Our system can be used for any PukiWiki site, not only a
specific site.

44. Comparisons with Related
Work
• Scripting Layer for Android (SL4A)
– brings popular scripting languages to Android.
– We uses our original language processor for the data
processor now.
– However the original language is not familiar with potential
users.
– We should use SL4A instead of using our original language
processor for this potential users of this M2M system.

45. Comparisons with Related
Work
• Broadcast
– Is an embedded web application for remote Android device
management.
– uses the SL4A.
– Enable Remote Monitoring/Remote Control of an android
device.
– However the Broadcast does not have the function for data
exchanging between web pages.

46. Comparisons with Related
Work
• Message Oriented Middleware (MOM)
– is software or hardware infrastructure supporting sending and
receiving messages between distributed systems.
– allows application modules to be distributed over
heterogeneous platforms and reduces the complexity of
developing applications that span multiple operating systems
and network protocols.
– Our data processor can be viewed as a MOM.

47. Concluding Remarks
• Successfully acquired remote room data and totaled up
the data using our M2M system.
• It is easy to define the data flow between wiki pages and
it is easy to analyze the data of the M2M system by just
writing programs on wiki pages.
• This easiness also can be a vulnerability of the security
and safety.

48. Concluding Remarks
• We are considering to enhance the security and safety of
the M2M system.
• It is not so difficult to make the data processor not only
for this M2M system but also for other purpose.
• We welcome the help of others who would like one to
participate in improving and making his or her own
sensor/actuator network.
