Sensor data sampling, mobile object, directional broadcast, and sensor networks
The idea of using mobile objects to gather samples from a sensor field has been recently proposed. A key challenge is how to gather the sensor data in a manner that is energy efficient with respect to the sensor nodes that serve as sources of the sensor data. In this paper, an algorithmic technique called Band-based Directional Broadcast is introduced to control the direction of broadcasts that originate from sensor nodes. The technique is studied by simulations that consider energy consumption and data deliverability.
