We consider the problem of correlated data gathering by a network with a sink node and a tree based communication structure, where the goal is to minimize the total trans- mission cost of transporting the information collected by the nodes, to the sink nod ...
A peer-to-peer overlay network is a logical network, built on top of a physical network. In contrast to classical client-server distributed architectures, peer-to-peer overlay networks allow location of resources without centralized control. Existing overl ...
We present DRIFT --- a total order multicast algorithm for ad hoc networks with mobile or static nodes. Due to the ad hoc nature of the network, DRIFT uses flooding for message propagation. The key idea of DRIFT is virtual flooding --- a way of using unrel ...
In this paper, we consider the problem of streaming video information on lossy packet networks with path and source diversity, such as wireless mesh networks or more generally overlay architectures. We propose to distribute the video information between se ...
Virtual private network design is the following NP-hard problem. We are given a communication network, represented as a weighted graph with thresholds on the nodes which represent the amount of flow that a node can send to and receive from the network. The ...
We consider the problem of bootstrapping self-organized mobile ad hoc networks (MANET), i.e. reliably determining in a distributed and self- organized manner the services to be offered by each node when neither the identity nor the number of the nodes in t ...
Channel allocation has been extensively studied in the framework of cellular networks, but the emergence of new system concepts, such as cognitive radio systems, bring this topic into the focus of research again. In this paper, we provide a formal analysis ...
The spectrum of deployed wireless cellular communication systems is found to be under-utilized, even though licensed spectrum is at a premium. To efficiently utilize the bandwidth left unused in a cellular system, which we denote as the primary system (PRI ...
The spectrum of deployed wireless cellular communication systems is found to be underutilized, even though licensed spectrum is at a premium. To efficiently utilize the bandwidth left unused in a cellular system, the primary system (PRI), we propose an ove ...
The spectrum of deployed wireless cellular communication systems is found to be under-utilized, even though licensed spectrum is at a premium. In this paper, we design a system with an ad hoc overlay network, which we denote as the secondary system (SEC), ...
