Applicability of a layered architecture adopting distributed data processing to M2M communications

We show that a layered architecture distributing M2M application to multiple processing entities in the M2M network is applicable for ubiquitous era. This paper firstly introduces a layered architecture of M2M system, where we put layers for the decomposition of application and the association of de-composited subroutines. Next, we categorize the association of subroutines into two patterns (sequential and random order), and model schemes on state managements (centralization and distribution). Then, we clarify the condition that the performance can be improved by distributed management in terms of processing time for two association patterns. Next, the deployment of de-composited subroutines on processing entities is discussed, where we show basic rules to reduce carried traffic. Finally, we address the requirements of messaging between two processing entities in M2M network to provide QoS such as time limitation.
