— In wireless sensor networks, minimizing power consumption and at the same time maintaining desired properties in the network topology is of prime importance. In this work, we p...
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...
In this paper we present a data dissemination protocol for efficiently distributing data through a sensor network in the face of node and link failures. Our work is motivated by t...
Manycast is a group communication primitive wherein the source is required to send data packets to a certain number of a given set of destinations. In this article, we design faul...
Selecting a small set of nodes called pivots, from all the nodes in a network and maintaining the routing infrastructure to and among each other can reduce routing overhead and ex...
