*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.

 

Potential Applications

• Obtaining data from multiple distributed sources such as:
  • Sensors communicating to a central receiver
  • Cooperative transmission by distributed sensors

 

Advantages

• Increased network capability
• Significant throughput savings
• Minimal polling
