Suppose G V,E) meet the fault-tolerant constraint.
Importantly, only FICTC achieves the fault-tolerant constraint between any two nodes.
Thus, for k-connectivity requirement, it is a coarse-grained fault-tolerant constraint, i.e., k-connectivity may not meet specific fault-tolerant requirement.
Then, the fault-tolerant constraint N ft (v i,v j) is {N}_{ft}left({v}_i,{v}_jright ge {k}_{i,j}kern2.5em left i,jin V,ine j,1le {k}_{i,j}le {k}_{ij}left( max right)right) (5).
The objective (6) is to minimize the maximum link interference, where ND v i ) denotes the neighboring set of v i. Fault-tolerant constraints in (7) emphasize the topology requirement between a specified node pair, which provides the flexibility for topology fault-tolerant requirement, and k ij is the value of specific fault-tolerant requirement.
Therefore, the optimization problem of topology control with fault-tolerant constraints for WMNs can be defined as min cdot max left{LISleft({v}_i,{v}_jright),{v}_iin V(G),{v}_jin NDleft({v}_iright)right} (6) mathrm{t}mathrm{o}n0.4em mathrm{N}_{ft}left: {v}_ift}left({v}_i,{v}_jright ge {k}_{i,j}kern2.5em left i,jin V,ine j,1le {k}_{i,j}le {k}_{ij}left( max right)right) (7).
In this context, the optimization consists in finding the instrumentation that satisfies the fault tolerant level constraints with the lowest financial cost.
Thus, the developed CPSO engine searches in a diverse variety of sensor networks to adopt the most fitted one based on the imposed fault-tolerant design constraints.
are tolerant to abiotic constraints such as salt stress or calcareous soils [ 24].
The comprehension of drought responses in upland rice is important for designing breeding strategies to develop varieties more tolerant to water constraints.
The emergence of new subpopulations, such as small-colony variants (genetic or adaptative diversification), persisters, and cells tolerant to imposed constraints, represents a new challenge for microbiologists, who will need to develop an integral, holistic view of the community.
