We propose a robust energy-aware clustering architecture for large-scale wireless sensor networks and analyze its performance in terms of throughput capacity and power consumption. The results show that clustered networks can achieve performance improvemen ...
In this paper we will propose a relaying scheme for wireless multi-hop networks. It is based on collaboration of intermediate relays at network layer to forward useful side information in place of dumbly forwarding packets. In our scheme we assume that the ...
We identify vulnerabilities in epidemic forwarding. We address broadcast applications over wireless ad-hoc networks. Epidemic forwarding employs several mechanisms such as inhibition and spread control and each of them can be achieved using different alter ...
The paper addresses the media-specific rate allocation problem in multipath networks. The streaming rate on each path is determined such that the end-to-end media distortion is minimized, when the receiving client aggregates packets received via multiple n ...
So far, the problem of positioning in wireless networks has been mainly studied in a non-adversarial setting. In this work, we analyze the resistance of positioning techniques to position and distance spoofing attacks. We propose a mechanism for secure pos ...
We show that network coding allows to realize significant 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 ...
The throughput of wireless networks is known to scale poorly when the number of users grows. The rate at which an arbitrary pair of nodes can communicate must decrease to zero as the number of users tends to infinity, under various assumptions. One of them ...
In this dissertation, we consider wireless multi-hop networks, where the nodes are randomly placed. We are particularly interested in their asymptotic properties when the number of nodes tends to infinity. We use percolation theory as our main tool of anal ...
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 ...
Self limiting epidemic forwarding is a method of epidemic information dissemination in wireless ad-hoc networks that achieves congestion control by limiting spread (i.e. the number of nodes that receive a given message) and injection rate in order to prese ...
