Fault-Tolerant Clustering in Ad Hoc and Sensor Networks
In this paper, we study distributed approximation algorithms for fault-tolerant clustering in wireless ad hoc and sensor networks. A k-fold dominating set of a graph G = (V, E) is...

Theoretically Good Distributed CDMA/OVSF Code Assignment for Wireless Ad Hoc Networks
Orthogonal Variable Spreading Factor (OVSF) CDMA code has the ability to support higher and variable data rates with a single code using one transceiver. A number of CDMA code ass...

Coloring unstructured wireless multi-hop networks
We present a randomized coloring algorithm for the unstructured radio network model, a model comprising autonomous nodes, asynchronous wake-up, no collision detection and an unkno...

Approximation algorithms for constructing wavelength routing networks
Consider a requirement graph whose vertices represent customers and an edge represents the need to route a unit of flow between its end vertices along a single path. All of these ...

Allowing each node to communicate only once in a distributed system: shared whiteboard models
In this paper we study distributed algorithms on massive graphs where links represent a particular relationship between nodes (for instance, nodes may represent phone numbers and ...
