Wireless Ad Hoc Networks are a particular paradigm where wireless devices communicate in a decentralized fashion, without any centralized infrastructure or decision. In order to avoid a situation where nodes chaotically try to communicate, distributed and ...
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 ...
The focus of this thesis is on the study of decentralized wireless multi-hop networks. We are particularly interested in establishing bounds on the traffic-carrying capabilities of wireless ad hoc networks and conditions on the scalability of such networks ...
Dynamic networks are those where the topology changes over time and therefore efficient routes need to be maintained by frequent updates. Such updates could be costly in terms of consuming throughput available for data transmission, which is a precious res ...
Wireless Mesh Networks (WMNs) are based on packet forwarding and therefore require efficient multi-hop protocols for their deployment. Toward this objective, we study the flow of packets through the network and using an analogy with fluid physics we classi ...
In the light of the ongoing electricity market integration in Europe, the debate has turned to a more regional approach of network access. Among other things, this leads to new questions with regard to the handling of congestion revenues. This paper explor ...
We consider the problem of efficiently processing subscription queries over data streams in large-scale interconnected sensor networks. We propose a scalable algorithm for distributed data stream processing, applicable on top of any platform granting acces ...
IEEE 802.11 is probably the most widely used, medium access control protocol in current wireless networks. In the Wireless LAN (i.e., single-hop) setting, its performance is by now quite well understood. However, in the multi-hop setting where relay nodes ...
We consider a wide-band ad-hoc network with coherent radios in a slow-fading environment, and we analyze the performance of different physical layer (PHY) and medium access (MAC) schemes in such a network. Most of the existing analysis assume that PHY is b ...
We present an architecture for implementing a wireless physical layer in a packet-based network simulator. We integrate this architecture in the popular ns-2 network simulator and use it to implement an impulse-radio ultra-wide band (IR-UWB) physical layer ...
