Receiving Data in a Sensor Network
First Claim
1. A method for receiving data from a plurality of transmitting devices at a receiving device, comprising:
- detecting a first data packet with a first signal strength;
detecting a second data packet with a second signal strength;
comparing the first and second signal strengths;
receiving the data packet with the stronger signal strength; and
multiplexing the data packet with the stronger signal strength responsive to comparing the first and second signal strengths.

Abstract
A sensor network has a plurality of wireless sensors which transmit to an intermediate receiving device which relays data to a central server. A method is provided for receiving data packets at the intermediate receiving device from a plurality of the transmitting devices. Data packets are sensed on a communication medium at the receiving device and the total traffic intensity of data packets from the transmitting devices is estimated. A detection threshold for data packets is provided and adapted as a function of the total intensity. The receiving device receives data packets with a signal strength above the current detection threshold.
