Optimizing data replication for expanding ring-based queries in wireless sensor networks
We consider the problem of optimizing the number of replicas for event information in wireless sensor networks, when queries are disseminated using expanding rings. We obtain clos...

Multipath fading in wireless sensor networks: measurements and interpretation
Multipath fading heavily contributes to the unreliability of wireless links, causing fairly large deviations from link quality predictions based on path loss models; its impact on...

Approximating Optimal Multicast Trees in Wireless Multihop Networks
— We study the problem of computing minimal cost multicast trees in multi-hop wireless mesh networks. This problem is known as the Steiner tree problem, and it has been widely st...

Hop distances and flooding in wireless multihop networks with randomized beamforming
We show that randomized beamforming is a simple yet efficient communication strategy in wireless multihop networks if no neighbor location information is at hand. Already small an...
