In this subsection, the steps required for the initialization of the system are presented.
Vital nodes between clusters (parts of the network) are calculated only once during the initialization of the system and consequently used with a constant time complexity.
First, it is invariant to the initialization of the system and is thus able to adapt very fast to changing environmental conditions.
During this process, the initialization of the system is completed including loading the device ontology, the construction of context base and the maintenance of a run-time model of contexts.
Assume that, after initialization of the system, all the messages mi have been stored in the Cloud CL with virtual addresses φ(x i ), and that a user Y retrieved the set of virtual addresses Φ(m') associated to m'. 1.
The Controller performs initialization of the system by allocating memory storage for the computed species concentrations of each model and the integrated model in Local Vectors, and Global Vector, respectively, as detailed in Appendix B. During this initialization, the initial species concentrations, S O,0, are set in the Global Vector.
After parameter initialization, the actual system frequency is estimated and the new sampling frequency is obtained; then, the relationship between the new sampling frequency and the ideal sampling frequency (60 or 50 Hz) is calculated, generating the factor λ. From this factor, the α is found and then the interpolation of the new sample is carried out.
When more nodes are initially active, the initialization phase of the system takes a different route because it is no longer required to start up the whole system.
Therefore, in the initialization, the global coordinate system should first be defined, and a part of the environment is reconstructed as an initial map in the global coordinate system.
In the case of workstations, for example, the authentication usually occurs in the system initialization, known as initial authentication.
