Demonstration of a Vehicle-to-Infrastructure (V2I) communication network featuring heterogeneous sensors and delay tolerant network capabilities
(2012)
The development of applications based over vehicular networks, such as road safety, environmental information etc. require a complete testbed platform for research and evaluation. Such a platform will be provided by NITOS[1] ...
Asymptotic laws for content replication and delivery in wireless networks
(2012)
A key consideration in novel communication paradigms in multihop wireless networks regards the scalability of the network. We investigate the case of nodes making random requests on content stored in multiple replicas over ...
The effect of caching in sustainability of large wireless networks
(2012)
We study the scalability of multihop wireless communications, a major concern in networking, for the case that users access content cached across the nodes. In contrast to the standard paradigm of randomly selected ...
Optimization driven multi-hop network design and experimentation: The approach of the FP7 project OPNEX
(2012)
The OPNEX project exemplifies system and optimization theory as the foundations for algorithms that provably maximize capacity of wireless networks. The algorithms termed in abstract network models have been converted to ...
Distributed back-pressure power control for wireless multi-hop networks
(2012)
A key problem in wireless networking is how to choose a link activation schedule and associated powers in concert with routing decisions to optimize throughput. Back-pressure control policies are optimal in this context, ...
A framework and experimental study for discrimination of collision and channel errors in wireless LANs
(2012)
A fundamental unresolved problem in wireless networks is that of distinguishing packet errors that are caused by deteriorated link conditions and noise, from errors that occur due to packet collisions. In this paper, we ...
