The use of directional wireless communications to form flexible mesh backbone networks, which provide broadband connectivity to capacity-limited wireless networks or hosts, promises to circumvent the scalability limitations of traditional homogeneous wireless networks. The main challenge in the design of directional wireless backbone (DWB) networks is to(More)
We introduce a challenging problem in establishing and initially configuring or bootstrapping a Free Space Optical (FSO) network. In such networks, it is assumed that each communication node is a base station, including a router and wireless optical communications hardware, and its number of transceivers is limited. In addition, the FSO networks are(More)
This paper focuses on the performance and scalability of mobile, base-station-oriented wireless networks, which have been the subject of research and development projects sponsored by the Defense Advanced Research Projects Agency. The background and rationale for such networks is presented as well as performance and scalability analyses of their routing,(More)

In this paper, we present new models and algorithms for control and optimization of a class of next generation communication networks: Hierarchical Heterogeneous Wireless Networks (HHWNs), under real-world physical constraints. Two biology-inspired techniques, a Flocking Algorithm (FA) and a Particle Swarm Optimizer (PSO), are investigated in this context.(More)
Recent technologies have enabled the formation of point-to-point directional wireless networks that are capable of dynamic changes in the network topology. The process of dynamically changing the network topology in response to changes in available link capacities and load demands is called topology control. Topology control involves the computation of new(More)
Initially configuring or bootstrapping a connected topology in directional wireless networks is a challenging problem, especially when nodes only have local connectivity information and a limited number of transceivers. This paper presents a scalable bootstrapping model which integrates: 1) a distributed bottom-up algorithm that constructs a spanning tree(More)
We have been looking at the properties of physical configurations that occur in nature in order to characterize, predict, and control network robustness in dynamic communication networks. Our framework is based on the definition of a potential energy function to characterize robustness in communication networks and the study of firstand second-order(More)
Free space optical (FSO) links for sensor networks can provide data rates that can range from bits/s to hundreds of Mb/s. In addition, FSO links using blue-green lasers or light emitting diodes can provide underwater communication over distances of tens of meters. Compared to acoustic technology, optical communication provides larger bandwidths, faster(More)
