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

Algorithm 4

Package reception rate estimation.

Require: Total number of probe packets sum and received from each neighbor node count recorded

Ensure: The neighbor node receives its own packet rate

1: Initialize: Substitute LQI after Kalman filter into Formula (4) to get ;

2: PRR←count/sum

3: ifsum>100then

4:  

5: else ifsum >50then

6:  αsum/100

7: else

8: end if
