Maximizing a Lifetime of Wireless Sensor Network by Scheduling

The increase in the demand for Wireless Sensor Networks (WSNs) has intensified studies which aim to obtain energy-efficient solutions, since the energy storage limitation is critical in those systems. Traditional methods for sensor scheduling use either sensing coverage or network connectivity, but rarely both Schedule sensor nodes work alternatively by configuring some of them an off-duty status that has lower energy consumption than the normal on-duty one. In a single wireless sensor network, sensors assume two main functionalities: sensing and communication. Minimizing energy consumption in a highly dense wireless sensor network needs to maximize off-duty nodes in both domains.
