I need to calculate the probability for delivery packets at the sink node. Each link has the probability for failure (p) so the probability for successful is (1-p). there are relay nodes between the sensor nodes and sink node, some relay nodes are forward the packets and another they do network coding.

if the relay just forwards the correctly received , How can calculate the probability of successful reception at the destination?

When relay nodes are applied network coding on the packets. How can compute the probability of successful delivery?

Could you explain by example?please

Best regards

Hisham
