Yes, there is *some* relation: they're positively correlated. But on the CC2420 radio, LQI shows significant variance for a given packet reception rate (PRR). You may be much better off using RSSI, which shows far less variance for a given PRR.
You can use (logistic) regression to determine the relationship the variables: - send a lot of packets between a lot of motes - compute the PRR as the fraction of packets received over the number sent for each tx, rx link pair - note the RSSI and LQI values - Plot (and regress) PRR vs RSSI and PRR vs LQI Hope that helps. - Prabal On 5/9/06, Venkat Manoj <[EMAIL PROTECTED]> wrote:
Hi all, Can anybody tell me if there is some relation between the link quality indiactor (LQI) and the probability of packet loss, between two motes? Or is there some method to find out the relation?
