Decomposing Data-Centric Storage Query Hot-Spots in Sensor Networks
2006
2006 3rd Annual International Conference on Mobile and Ubiquitous Systems - Workshops
Arising when a large percentage of queries is accessing data stored in few sensor nodes, query hot-spots reduce the Quality of Data (QoD) and the lifetime of the sensor network. All current In-Network Data-Centric Storage (IN-DCS) schemes fail to deal with query hot-spots resulting from skewed query loads as well as skewed sensor deployments. In this paper, we present two algorithms to locally detect and decompose query hot-spots, namely Zone Partitioning (ZP) and Zone Partial Replication
