Although the CCC saturation problem can be effectively alleviated, the hopping-based CCC requires stringent network-wide synchronization, which will significantly increase the complexity and cost.
First, most distributed DSA protocols rely on the time synchronization for better spectrum access coordination and some distributed DSA protocols even need the stringent network-wide synchronization, such as the time slotted protocols which will be introduced in Section 3.3.
We think the stringent networks performed less well because considerable amounts of data are excluded during the filtering process.
In the out-degree distribution, however, a number of peaks seem to be emerging in the less stringent networks.
These included an unprocessed interaction network along with two stringent networks that only considered interactions reported at least two or three times.
Our approach complements and expands the scope of diversity analyses based on direct BLAST searches, trees of ribosomal genes, relatively stringent networks of ribosomal genes, or 16S phylotypes, and should prompt further sequencing of complete environmental genomes by providing primers to probe diversity for cells with highly unusual genes.
Trait by trait correlations (Supporting Information Table S4) and a less stringent Bayesian network (Supporting Information Fig. S1) are also provided.
Costanzo-Stringent sub-network was constructed using the interaction score cut-offs ε < -0.17 or ε > 0.21.
Due to the size limitation on the sensor nodes and the life critical characteristics of the signals, there are stringent requirements on network's reliability and energy efficiency.
However, we also plan to map the CNCLib primitives to other protocols, such as HTTP, so that the developer can select the protocol that best suits the developer's application needs, as not all mobile nodes will necessarily have stringent resources and network limitations.
