On Mobility-Capacity-Delay Trade-off in Wireless Ad Hoc Networks
We show that there is a trade off among mobility, capacity, and delay in ad hoc networks. More specifically, we consider two schemes for mobility of nodes in ad hoc networks. We d...

Optimal relay assignment for cooperative communications
Recently, cooperative communications, in the form of keeping each node with a single antenna and having a node exploit a relay node's antenna, is shown to be a promising appr...

Design and Evaluation of a Routing-Informed Cooperative MAC Protocol for Ad Hoc Networks
—Cooperative relaying has been shown to provide diversity gains which can significantly improve the Packet Error Rate (PER) in wireless transmissions. In ad hoc wireless routing...

Cross-layer resource allocation over wireless relay networks for quality of service provisioning
— We propose a physical-datalink cross-layer resource allocation scheme over wireless relay networks for quality-ofservice (QoS) guarantees. By integrating information theory wit...

On Relay Node Placement and Assignment for Two-tiered Wireless Networks
Wireless networks that operate on batteries are imposed with energy constraints and long distance communications between nodes are not desirable. Implementing Relay Nodes (RNs) can...
