1. For each node that has non-expired MSDUs in its queue
2. Extract the network connectivity structure P (eq. (1), (2))
3. For the MSDU v existing at output of the queue of the sender node
4. For each path i p (network topology emanating from the sender node)
5. For each link , i j l of path i p
6. For each modulation strategy , ( ) i j m l
7. Calculate ( ) , i j l v e L , ( ) i v e L p , queue , ( ) i j d l from eq. (6),(7),(11)
8. Calculate max
i ?¤p from (15)-(17)
9. Under the calculated max
i ?¤p , evaluate eq. (12)
10. Compare with previous best, retaining the maximum (eq.(12))
11. Schedule the MSDU according to the established { } max*

Figure 5.3: Exhaustive algorithm for the determination of the cross-layer optimized meshnetwork
path selection, MAC retry limit and physical-layer modulation. The algorithm is
applied for each MSDU existing in the queue of each node in the multi-hop wireless network.
5.4.2 Optimization under a certain Horizon of Network Information
In this case we are only considering the part of the mesh network topology that
immediately connects to the node of interest.
