Group Testing Multiple Access: Efficient Communication in Sensor Networks
- 详细技术说明
- Using GTMA, sensor data in a wireless network can be efficiently collected with minimal polling, significant throughput savings, and increased network capabilities.
- *Abstract
-
As the number of sensors in a wireless network increases, it becomes impractical to use an individual polling process to collect sensor data at a central point, since significant bandwidth is needed to collect all data in a reasonable amount of time. Compression-based algorithms that reduce per-sensor throughput in individual polling are complex and lack general applicability. Group Testing Multiple Access (GTMA), however, achieves efficiency gains in a simpler manner by polling many sensors at once, only polling them again in smaller groups (or individually) if data from the larger group is non-uniform. Using GTMA, sensor data can be efficiently collected with minimal polling, significant throughput savings, and increased network capabilities.
