The role of control information in wireless link scheduling
… the CSI obtained from channel probes to make a scheduling decision. We investigate the optimal channel probing strategies and characterize the tradeoff between probing frequency and throughput. Furthermore, we characterize a fundamental limit on the rate at which CSI must be conveyed to the …

Low Complexity Scheduling in Wireless Networks
Scheduling complexity is an important bottleneck in the efficient design and controlof wireless networks. Owing to the high computational complexity of throughputoptimallink schedulers, low-complexity schedulers such as Greedy Maximal Scheduling(GMS)that often yield good throughput performance have …

Optimal control for wireless networks
… is to design an efficient routing, and wireless link scheduling policy, that maximizes net throughput. Currently, the only known throughput-optimal policy is the Backpressure policy for the unicast problem. In this thesis, we propose provably optimal algorithms for the broadcast and the …

Resource Allocation for Quality of Service in a Heterogeneous Network
"Finally, we consider a wireless down-link scheduling problem. We study a scheduling rule, which we call the exponential rule, and prove that this rule is throughput-optimal, i.e., it makes the queues stable if there exists any rule which can do so. In the proof we use the fluid limit technique, …

Cross-layer design for network performance optimization in wireless networks
… routing solutions. A sufficient condition on link bandwidth is proposed that makes a routing solution feasible, and then a mathematical optimization model based on this sufficient condition is provided. Simulation results show that joint optimization models can provide more feasible routing …

SCHEDULING IN PACKET SWITCHED CELLULAR WIRELESS SYSTEMS
… has been greatly increased on the downlink by using opportunistic schedulers at the base station. These schedulers exploit the multiuser diversity inherent in cellular systems. An interesting question is how opportunistic schedulers will provide Quality of Service(QoS) guarantees for a …

Airline alliances : the airline perspective
… connectivity through an alliance hub-to-hub linkage scheme on the increase in market share. The analysis shows that the alliance hub-to-hub link represents a significant source of additional traffic for the alliance. Accessibility, a measure developed for network connectivity, has proven to …

On Programmable Control and Optimization for Multi-Hop Wireless Networks
… network interference by joint efficient link scheduling and interference cancellation. • PCP in Tactical Wireless Networking. We propose the idea of the Programmable Control Plane (PCP) for the tactical wireless network under the protocol model. PCP decouples the control and data plane …

Advances in Stochastic Geometry for Cellular Networks
… by replacing the last-mile fibers with mm-wave links. We have proposed new stochastic geometry-based models for the performance analysis of IAB-enabled HetNets. Our analysis reveals some interesting system-design insights: (1) the IAB HetNets can support a maximum number of users beyond which …

Cognitive Gateway to Promote Interoperability, Coverage and Throughput in Heterogeneous Communication Systems
… to provide automatic traffic relaying and link establishment. The author extracts a scalable '“source-CG-destination“ snapshot from the entire network and investigates the key enabling technologies for such a snapshot. The CG features provide universal interoperability, which is enabled by …
