Network coding node placement for delay minimization in streaming overlays

Pascal Frossard, Nikolaos Thomos, Nicolae Cleju

Network coding has been proposed recently as an efficient method to increase network throughput by allowing network nodes to combine packets instead of simply forwarding them. However, packet combinations in the network may increase delay, complexity and e ...

Distributed rate allocation for multi-flow video delivery

We consider rate-distortion (RD) optimized multi-flow video delivery in unstructured overlay networks. We show that this problem can be studied as a distributed rate allocation. To solve the problem over the participating peers in the overlay, we apply cla ...

Utility-based Packet Scheduling in P2P Mesh-based Multicast

Pascal Frossard

We consider streaming video content over an overlay network of peer nodes. We propose a novel streaming strategy that is built on utility-based packet scheduling and proportional resource sharing in order to fight against free- riders. Each of the peers em ...

Optimizing TCP Receive Performance

Willy Zwaenepoel, Aravind Menon

The performance of the networking stack in an operating system depends on the overhead incurred by two of its components: the per-byte overhead incurred in data-touching operations, and the per-packet overhead of protocol processing and other operating sys ...

Distributed optimization of media flows in peer-to-peer overlay networks

We consider the problem of rate-distortion (RD) optimized media streaming in unstructured peer-to-peer (P2P) overlay networks. We formulate the aforementioned problem as a distributed rate allocation problem. To solve the problem for all the participating ...

Secure Position-Based Routing for VANETs

Panagiotis Papadimitratos, Charles Harsch

Vehicular communication (VC) systems have the potential to improve road safety and driving comfort. Nevertheless, securing the operation is a prerequisite for deployment. So far, the security of VC applications has mostly drawn the attention of research ef ...

Secure incentives to cooperate for wireless networks

Naouel Ben Salem

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 ...

Loss and Delay Accountability for the Internet

Olga Irzak, Aikaterini Argyraki

The Internet provides no information on the fate of transmitted packets, and end systems cannot determine who is responsible for dropping or delaying their traffic. As a result, they cannot verify that their ISPs are honoring their service level agreements ...

Non-cooperative behavior in wireless networks

Mark Felegyhazi

Existing cellular networks are centrally managed and require a tremendous initial investment. With the advancement of new wireless technologies, the operators of traditional networks have to face new competition. New technologies make it possible to provid ...

Nash Equilibria of Packet Forwarding Strategies in Wireless Ad Hoc Networks

Jean-Pierre Hubaux, Mark Felegyhazi, Levente Buttyan

In self-organizing ad hoc networks, all the networking functions rely on the contribution of the participants. As a basic example, nodes have to forward packets for each other in order to enable multi-hop communication. In recent years, incentive mechanism ...
