Rate adaptation for WiFi based wireless sensor devices

摘要

A rate selection method for WiFi based wireless sensor devices include storing parameters of communication packets successfully transmitted and received by a wireless device prior to turning off a wireless device, comparing a first set of parameters of a received communication signal to the parameters of the received communication packets and identifying at least one received communication packet of the communication packets based on the comparison of the first set of parameters. The rate selection method also includes comparing a second set of parameters of the received communication signal to the parameters of the identified at least one received communication packet to identify a close received communication packet of the identified at least one received communication packet and identifying a communication rate for current packets communicated by the wireless device based on the comparison of the second set of parameters.

1. A method comprising:
storing parameters of communication packets successfully transmitted and received by a wireless device prior to turning off the wireless device; comparing a first set of parameters of a current communication signal received after turning on the wireless device to the parameters of the received communication packets stored prior to turning off the wireless device; identifying at least one received communication packet of the received communication packets stored prior to turning off the wireless device based on the comparison of the first set of parameters; comparing a received signal strength indicator (RSSI) and carrier to interference-plus-noise ratio (CINR) of the current communication signal received after turning on the wireless device to an RSSI and CINR of the identified at least one received communication packet to identify a close received communication packet of the identified at least one received communication packet; and identifying a communication rate for current packets communicated by the wireless device based on the comparison of the RSSI and CINR of the current communication signal to the RSSI and CINR of the identified at least one received communication packet.
