Energy-efficient, lifetime balancing data collection techniques like [13] can be utilized here.
Yao et al. introduced an energy-efficient, delay-aware and lifetime-balancing data collection protocol for WSN.
These previous analyses demonstrated the economic merit of Option B+, and our analysis extends these findings by incorporating the possibility of multiple pregnancies over a woman's lifetime, and including primary data collection from antenatal clinics.
Energy efficiency analysis is notoriously difficult due to the network lifetime that depends on several factors, including network architecture, routing protocols, data collection initiation, lifetime definition, channel characteristics, and power consumption [8 10].
Set E i is the energy consumption of node i, so the network lifetime maximization can be expressed: Data collection with low delay.
For that purpose, socioeconomic appraisals must be realized not only ex ante, but also at the various stages of the project's lifetime, which requires constant efforts for data collection and consolidation.
An additional 50 participants were excluded from the analysis using the intensity-weighted lifetime exposure days because of incomplete data collection on factors related to the algorithm.
In [23], Luo and Hubaux jointly considered sink mobility and routing to maximize data collection during the network lifetime.
Moreover, optimal energy efficiency can be obtained in each divided sub-network; therefore, the WSN lifetime can be increased significantly and the data collection efficiency will be enhanced.
