LQ = The percentage of packets that are succesfully sent from youself to the neighbour
LQ = The percentage of packets that are succesfully sent from youself to the neighbour
ILQ = The percentage of packets that succesfully are sent from your neighbour to yourself also often called NLQ
ILQ = The percentage of packets that succesfully are sent from your neighbour to yourself also often called NLQ


ETX = Expected Trasnmission count = How many trasnmission attempts are required to get packets through = 1 / (LQ*ILQ)
ETX = Expected Trasnmission count = How many trasnmission attempts are required to get packets through = 1 / (LQ*ILQ)
