In dense mobile wireless sensor networks, it is desirable to reduce traffic for data gathering as much as possible while satisfying an application requirement. In this paper, focusing on an application which monitors the time-variant shape of events, we discuss an approach to achieve an efficient monitoring with small traffic in dense mobile wireless sensor networks.
In dense mobile wireless sensor networks, it is desirable to gather sensor data with as low traffic as possible. When an application requires geographical boundaries of sensor readings, it is able to satisfy the requirement while reducing traffic by gathering sensor data only from nodes located close to the boundaries. In order to do so, it is necessary to detect nodes located close to the boundaries...
In this paper, we propose an energy-efficient data gathering method, which is an extension of our previous method, to further reduce traffic in wireless sensor networks. Our previous method suppresses the energy consumption by traffic reduction utilizing spatial and temporal interpolation. In the extended method, each node appropriately utilizes either of spatial or temporal interpolation according...
