8.3 Solve the Basic First — The Physical Word 289<br />

Fig. 8.4 Use of standardised methodologies for optimizing 6lowpan and CoAP protocols tests.<br />

Constrained Application Protocol (CoAP) is a specialized web transfer<br />

protocol which is designed by CoRE working group of IETF keeping in mind<br />

the various issues of constrained environment to realize interoperations with<br />

constrained networks and nodes for machine to machine (M2M) applications<br />

like smart energy, building automation, smart home etc. CoAP could be one of<br />

the technologies identified for Internet of Things vision. Here again there are<br />

good progresses toward interoperability with interoperability events organised<br />

[40] but there is still a need for finalizing further test specifications and<br />

tools.<br />

Probe-IT project develop some tests and tools on CoAP and 6lowPAN to<br />

demonstrate that it is possible to use market proof test methodologies which<br />

can be used for such protocols and can bring a lot of level of optimization and<br />

automation leading to improve quality while reducing time and costs.<br />

Finally to guarantee a global (technical) interoperability of future interconnected<br />

objects, the previous examples described below show that there is an<br />

urgent need to coordinate all these initiatives with a roadmap including some<br />

common agreed method(s) that will help in answering at least the following<br />

questions:<br />

• Are the existing testing methods suitable enough for these high<br />

combinatory complexities in IoT testing?
