Room geometry estimation from acoustic echoes using graph-based echo labeling

Ingmar Jager, Richard Heusdens, Nikolay D. Gaubitch
2016 2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)  
In this paper we propose a distributed reformulation of the linearly constrained minimum variance (LCMV) beamformer for use in acoustic wireless sensor networks.  ...  without the need for sharing raw data within the network.  ...  In [22] a distributed delay and sum BF utilising randomised gossip is proposed. While operating in any undirected network, this method only minimises the presence of uncorrelated noise.  ...

A Survey of Geographical Routing in Wireless Ad-Hoc Networks

Fraser Cadger, Kevin Curran, Jose Santos, Sandra Moffett
2013 IEEE Communications Surveys and Tutorials  
Geographic routing protocols have been designed for a variety of applications ranging from mobility prediction and management through to anonymous routing and from energy efficiency to QoS.  ...  Geographic routing protocols eliminate dependence on topology storage and the associated costs, which also makes them more suitable to handling dynamic behavior frequently found in wireless ad-hoc networks  ...  Aside from energy consumption other areas of WSN research that are expanding are QoS and security, in a manner similar to conventional adhoc networking.  ...
