—In a sensor network, an important problem is to provide privacy to the event detecting sensor node and integrity to the data gathered by the node. Compromised source privacy can...
—Distributed transmit beamforming has recently been proposed as a technique in which several single-antenna sources cooperate to form a virtual antenna array and simultaneously t...
In this paper we address the minimum-energy broadcast problem in multi-hop wireless networks, so that all broadcast requests initiated by different source nodes take place on the s...
In this paper we consider a distributed and efficient information dissemination and retrieval system for wireless sensor networks. In such a system each sensor node operates auton...
In this paper, network hosted transcoding is studied for the optimization of resources in multicast applications. The configuration is as follows: one source node is sending a sig...

We present an algorithm which given a source node and a set of n - 1 target nodes in the (n, k)-star graph Sn,k, where all nodes are distinct, builds a collection of n - 1 node-di...
Abstract— In this paper, we evaluate the performance improvement in an Orthogonal Frequency-Division Multiple Access (OFDMA) uplink achievable with cooperative relaying in the pr...

We consider the design and performance analysis of adaptive modulation and coding (AMC) applied to regenerative dual-hop transmission systems, where a source node communicates with...
In this paper, we consider a MIMO wireless relay network where communication between a source and a destination node is assisted by multiple relay nodes using the Amplifyand-Forwar...
We consider the problem of computing an optimal range assignment in a wireless network which allows a specified source station to perform a broadcast operation. In particular, we ...
