Secure incentives to cooperate for wireless networks

The operating principle of certain wireless networks makes essential the cooperation between the mobile nodes. However, if each node is an autonomous selfish entity, cooperation is not guaranteed and therefore we need to use incentive techniques. In this t ...

Network Coding Applications

Christina Fragouli, Emina Soljanin

Network coding is an elegant and novel technique introduced at the turn of the millennium to improve network throughput and performance. It is expected to be a critical technology for networks of the future. This tutorial deals with wireless and content di ...

On feedback for network coding

Christina Fragouli

In this paper we examine possible ways that feedback can be used, in the context of systems with network coding capabilities. We illustrate, through a number of simple examples, that use of feedback can be employed for parameter adaptation to satisfy QoS r ...

A Network Coding Approach to Energy Efficient Broadcasting: from Theory to Practice

Jean-Yves Le Boudec, Christina Fragouli, Jörg Widmer

We show that network coding allows to realize energy savings in a wireless ad-hoc network, when each node of the network is a source that wants to transmit information to all other nodes. Energy efficiency directly affects battery life and thus is a critic ...

Media-Specific Rate Allocation in Heterogeneous Wireless Networks

Pascal Frossard, Dan Jurca

We address the problem of joint path selection and rate allocation in multipath wireless streaming, in order to optimize a media specific quality of service. We leverage on the existence of multiple parallel wireless services, in order to enhance the recei ...

Reliable Broadcast in Wireless Mobile Ad Hoc Networks

André Schiper, David Cavin, Yoav Sasson

We propose a single source reliable broadcasting algorithm for linear grid-based networks where a message is guaranteed to be delivered to all the nodes of the network. The nodes are mobile and can move from one grid point to another. The solution does not ...

Computing over multiple-access channels with connections to wireless network coding

Michael Christoph Gastpar

We study the problem of multicasting over a network of multiple-access channels (MACs). The separation-based solution to this problem is to reduce each MAC to a set of noiseless bit pipes via a channel code and,then employ network coding. Sometimes, howeve ...

On Average Throughput Benefits and Alphabet Size in Network Coding

Christina Fragouli, Emina Soljanin

We examine the throughput benefits that network coding offers with respect to the average through- put achievable by routing, where the average throughput refers to the average of the rates that the indi- vidual receivers experience. We relate these benefi ...

A framework for network coding in challenged wireless network

Jean-Yves Le Boudec, Alaeddine El Fawal, David Cavin, Yoav Sasson

Network coding is an area that has emerged in 2000, and has since then attracted an increasing interest, as it promises to have a significant impact in both the theory and practice of networks. To evaluate its performance in realistic situation, we develop ...
