The current picture
�M2M is just starting if we think to market forecasts: from Wikipedia: “TheM2M device, software, network, and service market is expected to grow rapidly world widebetween now and 2010. Some estimates suggest the 2010 world market may exceed $300Bin annual revenue. Where as there are some 500 M computers in the world and 1.5 B cellphones & PDAs, it is estimated there are more than 38B other electronic devices that haveinformation perhaps relevant to improving an enterprises operation.”
�There could be the most appropriate network protocol but in the actual(and future) situation many different protocols are used for differentapplications domain
�On the network protocol side, open standards will enable interoperabilityamong different networks
�On the service side, application developers should be provided with aservice platform offering a standard interface to network objects in atechnology agnostic way

What is needed?�A standard protocol with some specific requirements to interconnect the“machines” :
� Range (multihop)
� Data rate
� Low power (battery duration)
� Latency
� Low cost
� Application domain
�A gateway to connect the local network (PAN, LAN, ..) to a backbone network inorder to access the “machines” remotely through a standard interface
�A management platform providing:� Typical network management features (such as configuration, commissioning, ..)
� Access to M2M networks in a protocol independent way
� Integration of M2M networks with other TLC services
� High level standard interfaces for application providers to build services using the M2Mnetworks enabling:
� a single application to access multiple WSNs, tag networks, networked objects
� a single WSN, a tag, networked objects to be accessed by differentapplications
� Network size (number of nodes)
� Security
� Suitable for batter-less devices

The system enables a real time monitoringthrough a web interface:
• Indoor Environmental condition and outdoorparameters (e.g. light, temperature, humidity,presence)
• Functionality of the refrigerator systems (AirManagement Unit)
• Continuous currents measured in differentareas (e.g. commutation, transmission, access)
• Alternated currents for conditioning system(e.g. HVAC and free-coolers)
Moreover the system enable to improve theefficiency of the energy system by planningmodifications and estimate the value of the WSN
The system is based on a ZigBee StandardWireless Sensor Network technology.
• Self-configuring short range network• Low cost• The battery operated sensors have a battery-life of years

�SPINE (Signal Processing in Node Environment) is an Open Source software Framework fordistributed Signal Processing in Wireless Sensor Networks.�SPINE has two main SW components: one to be executed on the sensor nodes and the otheron the BSN coordinator.�SPINE’s goals:
� Collect sensors’ data and deduce information understandable from final users (build services)� Decrease development time for signal processing algorithms� Build a community based on the open source framework
� Enable interoperability among applications.

Conclusions
�Uprising scenario for M2M shows ecosystems with billions of objectsinterconnected through plenty of networks using several protocols�Interoperability, security and management will be key factor for developingbusiness opportunities and for assuring reliable services�This can be achieved through openness and standardisation of protocols andinterfaces of all network infrastructure nodes�Key aspects for a Telco operator are
• Multiple application domains• High Security Level• Chipsets availability, low cost & low power solution
• Easy integration in appliance/terminals in miniaturized peripherals with integratedantenna
• Easy connection of networks with the operator traditional network infrastructure andinformation technology
• Sensing and controlling things directly from the Telco asset (e.g. phone, SIM card)
• Creating extended operating networks
