Enhanced data exchange capabilities for M2M applications

Machine-to-Machine Service Architecture is being developed and standardized to build a universal horizontal integration platform for many devices and domains. Related visions such as Smart Home, Smart Cities and Intelligent Transportation Systems are realized by distributed M2M applications. Thusly, adequate data exchange capabilities are significant, since the ability to tailor the actual data exchange to the requirements of the use-case directly relates to the resulting network requirements. This paper investigates the status quo of data exchange and interworking of M2M applications and devices based on an automotive scenario. This motivates enhancements; in particular data-dependent filter criteria for subscribe/notify mechanism including local aggregation and harmonization of different subscriptions on the same resource. Lastly, two alternative approaches to implement these enhancements are presented and discussed.
