Directional wireless communication facilitates mobile and broadband wireless connectivity. Hierarchical architectures are adopted with diverse communication technologies and node capabilities at different layers. HHWNs use a wireless backbone network consisting of a set of base stations or backbone nodes that use directional wireless communications. Two biology-inspired techniques are used for the Hierarchical Heterogeneous Wireless Networks (HHWNs) management. They are Flocking Algorithm (FA) and Particle Swarm Optimizer (PSO). Nonconvex mathematical model is initiated for HHWN control and optimization.
