BARP-A Dynamic Routing Protocol for Balanced Distribution of Traffic in NoCs to Avoid Congestion

Pejman Lotfi Kamran

A novel routing algorithm, named Balanced Adaptive Routing Protocol (BARP), is proposed for NoCs to provide adaptive routing and ensure deadlock-free and livelock-free routing at the same time. By evenly distributing input packets of a router among all its ...

Distributed target localization via spatial sparsity

Volkan Cevher

We propose an approximation framework for distributed target localization in sensor networks. We represent the unknown target positions on a location grid as a sparse vector, whose support encodes the multiple target locations. The location vector is linea ...

On Clustering Phenomenon in Mobile Partitioned Networks

Matthias Grossglauser, Natasa Sarafijanovic-Djukic

According to different kinds of connectivity, we can distinguish three types of mobile ad-hoc networks: dense, sparse and clustered networks. This paper is about modeling mobility in clustered networks, where nodes are concentrated into clusters of dense c ...

Mobility-Centric Geocasting For Mobile Partitioned Networks

We describe our design of a geocast service for mobile partitioned networks (MPNs). We focus mainly on minimizing the delivery latency. Our approach exploits the time-stability of the collective mobility pattern. In MPNs, in contrast to MANETs, the end-to- ...

Routing in large-scale buses ad hoc networks

Michel Sède, Da Li

A Disruption-Tolerant Network (DTN) attempts to route packets between nodes that are temporarily connected. Difficulty in such networks is that nodes have no information about the network status and contact opportunities. The situation is different in publ ...

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 ...

Modelling the IEEE 802.11 protocol in wireless multi-hop networks

Mathilde Durvy

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 ...

Hierarchical Routing in Dynamic $\alpha$-Doubling Networks

Matthias Grossglauser, Suhas Diggavi, Dominique Florian Tschopp

In this paper we formulate the problem of routing over dynamic networks with finite doubling dimension. This is motivated by communication in mobile wireless networks, where the communication graph topology changes over time, but has some geometric propert ...

Hierarchical Routing over Dynamic Wireless Networks

Matthias Grossglauser, Suhas Diggavi, Dominique Florian Tschopp

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 ...

Robust Routing for Dynamic Wireless Networks Based on Stable Embeddings

Matthias Grossglauser, Suhas Diggavi, Dominique Florian Tschopp, Jörg Widmer

Routing packets is a central function of multi-hop wireless networks. Traditionally, there have been two paradigms for routing, either based on the geographical coordinates of the nodes (geographic routing), or based on the connectivity graph (topology-bas ...
