Performance Analysis of the CONFIDANT Protocol: Cooperation Of Nodes - Fairness In Dynamic Ad-hoc NeTworks

Jean-Yves Le Boudec, Sonja Buchegger

Mobile ad-hoc networking works properly only if the participating nodes cooperate in routing and forwarding. However, it may be advantageous for individual nodes not to cooperate. We propose a protocol, called CONFIDANT, for making misbehavior unattractive ...

Scalable routing protocols with applications to mobility

Ljubica Blazevic

In this thesis we study two routing problems related to mobility. The first problem concerns scalable multicast routing when there is a large number of multicast groups with a small number of receivers. Existing dense and sparse mode routing protocols have ...

Malice, Selfishness, and Slander in Mobile Ad-hoc Networks.

Jean-Yves Le Boudec, Sonja Buchegger

In mobile ad-hoc networks nodes need to cooperate to communicate, but there are many reasons for non-cooperation. Saving power or preventing other nodes from obstructing a service are merely selfish reasons for non-cooperation, whereas nodes may also activ ...

A Scalable Routing Method for Irregular Mobile Ad Hoc Networks

Jean-Yves Le Boudec, Ljubica Blazevic

We designed the terminode routing protoc ol with the objective to scale in large mobile ad hoc networks where the topology, or node distribution, is irregular. Our routing protocol is a combination of two protocols: Terminode Local Routing (TLR - to reach ...

Path Set Selection in Mobile Ad Hoc Networks

Panagiotis Papadimitratos

Topological changes in mobile ad hoc networks frequently render routing paths unusable. Such recurrent path failures have detrimental effects on the network ability to support QoS-driven services. A promising technique for addressing this problem is to use ...

Secure Routing for Mobile Ad hoc Networks

Panagiotis Papadimitratos

The emergence of the Mobile Ad Hoc Networking (MANET) technology advocates self-organized wireless interconnection of communication devices that would either extend or operate in concert with the wired networking infrastructure or, possibly, evolve to auto ...

Self Organized Terminode Routing

Jean-Yves Le Boudec, Ljubica Blazevic

We consider the problem of routing in a wide area mobile ad-hoc network called Terminode Network. Routing in this network is designed with the following objectives. First, it should scale well in terms of the number of nodes and geographical coverage ...

Route Driven Gossip: Probabilistic Reliable Multicast in Ad Hoc Networks

Jean-Pierre Hubaux, Jun Luo, Patrick Eugster

Traditionally, reliable multicast protocols are deterministic in nature. It is precisely this determinism which tends to become their limiting factor when aiming at reliability and scalability, particularly in highly dynamic networks, e.g., ad hoc networks ...

Load Balancing in Data Networks

Load balancing apparatus for a data communications network comprises hash logic for computing a hash function on incoming data packets. A threshold detector is connected to the hash logic for triggering, in response to utilization of the downstream objects ...

Space-Time Coding for Broadband Wireless Transmission

Christina Fragouli

We present an overview of research activities on space-time coding for broadband wireless transmission performed at AT & T Shannon Laboratory over the past two years. The emphasis is on physical layer modem algorithms such as channel estimation, equalizati ...
