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

When data productions and consumptions are heavily unbalanced and when the origins of data queries are spatially and temporally distributed, the so called in-network data storage paradigm supersedes the conventional data collection paradigm in Wireless Sensor Networks (WSNs). In this paper, the authors first introduce geometric quorum systems (along with their metrics) to incarnate the idea of in-network data storage. These quorum systems are "Geometric" because curves (rather than discrete node sets) are used to form quorums. They, then propose GeoQuorum as a new quorum system, for which the quorum forming curves are parameterized.
