A Hybrid Reliable Routing Algorithm Based on LQI and PRR in Industrial Wireless Networks

Algorithm 1

One-dimensional Kalman filter algorithm.

Require: the value of the LQI with additive Gaussian white noise and the result of the last filter and other parameters of the Kalman filter

Ensure: filtered results

1: initialize: p ←1; R ←1;LQI ←the result after the last filtering

2: while value of LQI with noise X read in do

3:  

4:  

5:  

6: end while

7: return LQI
