M2M Application Framework Software Design

AVIDdirector-M2M comes complete with AVIDWireless’ M2M Application Framework (M2MApp) to facilitate

rapid development and deployment of M2M and Telemetry applications. It provides far more power than the

J2ME Midlet environment since it provides most of the communication, device and system management

functions that a developer would normally have to write and test. When we use the term framework, we refer to

an object-oriented framework defined Ralph Johnson and Brian Foote

as: "A set of classes that embodies an

abstract design for solutions to a family of related problems". M2MApp will allow developers to generate

applications enabling higher productivity and shorter development time. The framework deals with the network

infrastructure that handles the communication between M2M device and M2MXML server, management of

sensors and I/O devices on the AVIDdirector-M2M and provides an applications interface for fast and easy

development.

The overall view of how the AVIDdirector-M2M, M2MXML and the M2MXML portal fit together is:

AVIDdirector-M2M device performs the actual control and monitoring of remote devices and sensors. They can

be programmed to do this either by:

§ M2MXML. M2MXML provides a robust, extensible language to specify both direct remote control of the

M2M devices and also on-board intelligent behavior. This allows a M2MXML Server to automatically

configure AVIDdirector-M2M devices to the particular device or situation and perform complex tasks

without writing a custom application on the device. The M2MXML Server can be written in any language

(.NET, Java, PHP) since the sole specification and interface between the AVIDdirector-M2M device and

the Server is the M2MXML specification

§ Writing a custom M2Mlet. M2Mlets are small applications that handle the direct control and monitoring

of devices and performing operations either too complex for M2MXML or on-device behaviors which are
