Adaptive Hierarchical Clustering Algorithm (AHCA) maps a flat topology to a hierarchical tree though output trees are incontrollable and are not suitable for multimedia. Prune-Relocate operation and Top Topologies operation are proposed in this paper to improve AHCA protocol and generate OM-AHCA trees. Numerical simulations show that OM-AHCA trees are compromise between AHCA trees and single-level topology flat protocol trees, which optimize the overall performance of single-level flat protocol and improve the degree metric of AHCA trees.
