Speculative Packet Reception

1. Predict arriving packets and their arrival pattern. 2. Verify prediction.

Packet Decoding

No information is known about the packet at decoding time.

13 dB gain translates to 4x range in free space.

Performance Gain

It is possible to build a protocol on top of existing protocols for low-rate transmission (notification). Our approach can increase the effective range for low energy sensors. Error Rate

Conclusion

We have proposed a novel approach for low-power sensors to communicate at lower SNR compared to conventional approach.
