The balanced unicast and multicast capacity regions of large wireless networks
We consider the question of determining the scaling of the n2 -dimensional balanced unicast and the n2n dimensional balanced multicast capacity regions of a wireless network with ...

Spherical representation and polyhedron routing for load balancing in wireless sensor networks
—In this paper we address the problem of scalable and load balanced routing for wireless sensor networks. Motivated by the analog of the continuous setting that geodesic routing ...

Channel Aggregation in Cognitive Radio Networks with Practical Considerations
—In cognitive radio (CR) networks, licensed spectrum that can be shared by secondary users (SUs) is always restricted by the needs of primary users (PUs). Although channel aggreg...

Diverse Routing in Networks with Probabilistic Failures
—We develop diverse routing schemes for dealing with multiple, possibly correlated, failures. While disjoint path protection can effectively deal with isolated single link failur...

Iso-Contour Queries and Gradient Descent with Guaranteed Delivery in Sensor Networks
—We study the problem of data-driven routing and navigation in a distributed sensor network over a continuous scalar field. Specifically, we address the problem of searching fo...
