Optimal Routing and Power Allocation for Wireless Networks with Imperfect Full-Duplex Nodes
… interference cancellation and solve the routing and power allocation problem in this network. We use a model that focuses on the effects of full-duplex by including residual self-interference and one hop interference while other interfering signals are considered negligible in comparison. …

Performance evaluation of routing metrics for wireless mesh networks
An optimal routing metric has a potential to improve performance of a wireless network. A number of routing metrics were designed with mobile ad hoc networks (MANETs) in mind. These routing metrics might be useful in wireless mesh networks (WMNs) but the fact that WMNs and MANETs are two different …

Towards practical policies for network control
… policies geared towards achieving throughput optimality have been developed. However, rarely any of these policies have been used in practice. We study three different issues that impede this transition and propose solutions that can facilitate the move. Throughput optimal routing policies are …

An adaptive strategy for providing dynamic route guidance under non-recurrent traffic congestion
… designing these systems is in the development of optimal routing strategies that would maximize the benefits to overall system as well as individual users. Infrastructure based DRGS have advantage of pursuing system optimal routing strategy, which is more essential under abnormal traffic …

Optimal adaptive routing and traffic assignment in stochastic time-dependent networks
… time-wise and link-wise stochastic dependency. A routing policy is a decision rule which specifies what node to take next out of the current node based on the current time and online information. A formal framework is established for optimal routing policy problems in STD networks, including …

Practical algorithms for distributed network control
Optimal routing and scheduling algorithms have been studied for decades, however several practical issues prevent the adoption of these network control policies on the Internet. This thesis considers two distinct topics in distributed network control: (i) maximizing throughput in wireless networks …
