GeoQuorum: Load Balancing and Energy Efficient Data Access in Wireless Sensor Networks [article]

Jun Luo, Ying He
2011 arXiv   pre-print
We then propose GeoQuorum as a new quorum system, for which the quorum forming curves are parameterized.  ...  These quorum systems are "geometric" because curves (rather than discrete node sets) are used to form quorums.  ...  Geometric quorum systems designed using planar curves in 3D.  ...

“We propose a new scheme for constructing a k-coterie with small quorums; the size of each quorum is O((1/e)n‘!+3#)/2) when k=n* (0<e< 1/3), and O(./nlogn) when k = O(1).”  ...  This problem can be solved using the k- coterie: We first prepare a set (k-coterie) @ of sets (quorums) Q of processes such that each k-set {Q),---,Q,} of quorums in & contains a pair Q; and Q; (i # j)  ...

Efficient Synthesis and Evaluation of Quorum-Sensing Modulators Using Small Molecule Macroarrays

2009 Organic Letters  
A focused library of AHLs was constructed, and the macroarray platform was found to be compatible with both solution and agar-overlay assays using quorum-sensing (QS) reporter strains.  ...  Bacteria can assess their local population densities and environment using a cell-cell signaling process called quorum sensing (QS). 1 This phenomenon allows bacteria to coordinate group behavior and  ...  The absence of toxic CNBr in the current route, however, coupled with the ease of planar support manipulation versus beads, is advantageous.  ...
