Calculation of the Duty Cycle for BECA

open access: yesInternational Journal of Computer Applications, 2015
Consumption of energy is one of the major problems in wireless sensor network, as sensor nodes driven on battery power. Therefore, it is intended to minimize the power consumption by putting the wireless interface of the sensor nodes in low power sleep mode.
