Energy-efficient model for indoor localization process based on wireless sensor networks

Although the research made in the field of indoor localization based on wireless sensor networks (WSN) has shown encouraging and sometimes adequate results in terms of position estimation accuracy, raising the network longevity is still a challenging issue especially when the used sensor nodes are battery-powered and their energy capacity is very limited. In this paper we present an energy efficient approach for indoor localization purpose that is based on optimizing the activity periods of the sensor nodes during the indoor localization process.
