Hierarchical Optimization Handoff Algorithm
Open path :
- If it is unable to find a closed path in both Layers 1 and 2, then it will attempt to find an open path, which is on where the last hop is unsynchronized.
HOHA searches for a path that jointly minimizes the path length and maximizes the number of spare channels in the destination microcell, i.e.,the last microcell in the last hop.
