An O(log n) Dominating Set Protocol for Wireless Ad-Hoc Networks under the Physical Interference Model ∗ ABSTRACT (2009)

Christian Scheideler, Andrea W. Richa

Dealing with interference is one of the primary challenges to solve in the design of protocols for wireless ad-hoc networks. Most of the work in the literature assumes localized or hopbased...

Rajmohan Rajaraman, Andrea W. Richa

Consider an arbitrary distributed network in which large numbers of objects are continuously being created, replicated, and destroyed. A basic problem arising in such an environment is that of...

The power of two random choices: a survey of techniques and results (2001)

Michael Mitzenmacher, Andrea W. Richa, Ramesh Sitaraman

To motivate this survey, we begin with a simple problem that demonstrates a powerful fundamental idea. Suppose that n balls are thrown into n bins, with

Approximation Algorithms for the Mobile Piercing Set Problem with Applications to Clustering in Ad-hoc Networks (2001)

Hai Huang, Andrea W. Richa, Michael Segal

The main contributions of this paper are two-fold. First, we present a simple, general framework for obtaining ecient constant-factor approximation algorithms for the mobile piercing set (MPS)...

Randomized Protocols for Low-Congestion Circuit Routing in Multistage Interconnection Networks (1998)

Richard Cole Bruce, Bruce M. Maggs, Friedhelm Meyer, Heide Michael Mitzenmacher, Andrea W. Richa, Klaus Schroder, ...

In this paper we study randomized algorithms for circuit switching on multistage networks related to the butterfly. We devise algorithms that route messages by constructing circuits (or paths) for...

New Approximation Techniques for Some Ordering Problems, (1997)

Rao, Satish, Richa, Andrea W.

We describe O(log n) times optimal approximation algorithms for the NP-hard graph optimization problems of minimum linear arrangement, minimum containing interval graph and minimum storage-time...

Fast Algorithms for Finding O(Congestion + Dilation) Packet Routing Schedules, (1997)

Leighton, F. T., Maggs, Bruce M., Richa, Andrea W.

In 1988, Leighton, Maggs, and Rao showed that for any network and any set of packets whose paths through the network are fixed and edge-simple, there exists a schedule for routing the packets to...

Accessing Nearby Copies of Replicated Objects in a Distributed Environment (1997)

C. Greg Plaxton, Rajmohan Rajaraman, Andrea W. Richa, Andr'ea W. Richa

Consider a set of shared objects in a distributed network, where several copies of each object may exist at any given time. To ensure both fast access to the objects as well as efficient utilization...

Consider a set of shared objects in a distributed network, where several copies of each object may exist at any given time. To ensure both fast access to the objects as well as efficient utilization...

Tight Analyses of Two Local Load Balancing Algorithms (1995)

Bhaskar Ghosh, F. T. Leighton, Bruce M. Maggs, S. Muthukrishnan, C. Greg Plaxton, R. Rajaraman, ...

. This paper presents an analysis of the following load balancing algorithm. At each step, each node in a network examines the number of tokens at each of its neighbors and sends a token to each...
