Beyond Trees: MRF Inference via Outer-Planar Decomposition
Maximum a posteriori (MAP) inference in Markov Random Fields (MRFs) is an NP-hard problem, and thus research has focussed on either finding efficiently solvable subclasses (e.g. t...

Distributed estimation of channel gains in wireless sensor networks
We consider the problem of distributed channel estimation in a sensor network which employs a random sleep strategy to conserve energy. If the N network nodes are randomly placed a...

Content based multicast (CBM) in ad hoc networks
Abstract— This paper presents a radically new multicast model for ad hoc wireless networks. In this model, the content of the multicast data determines the receiver set for the d...
