An Energy Reporting Aggregation Method Based on EAFM and DTRM in WSN

Analyzed the energy consumption disciplinarian of the nodes in WSN, the node's energy attenuation forecast model (EAFM) can be established. A difference-threshold reporting mechanism (DTRM) is used to report the residual energy of nodes. The energy collection mechanism based on EAFM and DTRM can reduce energy data reporting times significantly, improve the efficient of energy data collection, save the node's energy at the same time. The experiments in the platform of telosb nodes show that the predicable rate is between 70% and 85%, and this method can extend the node's life by 1% ~ 4.5%.
