A Two-Tier Data Dissemination Model for Large-scale Wireless Sensor Networks
, 2002
"... networking. It suggests that information about each mobile sink's location be continuously propagated through the sensor field to keep all sensor nodes updated with the direction of forwarding future data reports. Unfortunately frequent location updates from multiple sinks can lead to both exce ..."

grid structure which enables mobile sinks to continuously receive data on the move by flooding queries within a local cell only. TTDD's design exploits the fact that sensor nodes are stationary and location-aware to construct and maintain the grid structures with low overhead. We have evaluated
Sinks, Stationary Regions and Thoroughfares in Object Mobility Databases
, 2005
"... Abstract. As mobile devices proliferate and networks become more locationaware, the corresponding growth in spatio-temporal data will demand analysis techniques to mine patterns that take into account the semantics of such data. Association Rule Mining (ARM) has been one of the more extensively stud ..."

-temporal association rules (STARs) that describe how objects move between regions over time. We define support in the spatio-temporal domain to effectively deal with the semantics of such data. We also introduce other patterns that are useful for mobility data; stationary regions and high traffic regions. The latter

Maximizing the Lifetime of Wireless Sensor Networks with Mobile Sink in Delay-Tolerant Applications
- Mobile Computing, IEEE Transactions on
, 2010
"... Abstract—This paper proposes a framework to maximize the lifetime the wireless sensor network (WSN) by using a mobile sink when the underlying applications tolerate delayed information delivery to the sink. Within a prescribed delay tolerance level, each node does not need to send the data immediate ..."

the lifetime of the WSN subject to the delay bound constraints, node energy constraints and flow conservation constraints. We conduct extensive computational experiments on the optimization problems and find that the lifetime can be increased significantly as compared to not only the stationary sink model

Hammersley’s process with sources and sinks
, 2005
"... We show that, for a stationary version of Hammersley’s process, with Poisson “sources” on the positive x-axis, and Poisson “sinks ” on the positive y-axis, an isolated second class particle, located at the origin at time zero, moves asymptotically, with probability one, along the characteristic of a ..."

ON STATIONARY DIFFUSION IN HETEROGENEOUS MEDIA
"... This work concerns steady state diffusion in a medium containing a random distribution of sinks. The physical properties of the medium are described in terms of geometrical correlation functions, for example, two or three point correlations. Variational principles of classical type are developed and ..."

STP Stationary phase
, 2010
"... Abstract The partitioning of reducing power into different electron-accepting pathways was evaluated during growth and stationary phases of H2-producing Rhodobacter sphaeroides cultures. For this, an electron balance method was developed using the chemical oxygen demand concept to quantitatively ana ..."

. The other two major electron sinks in the growth phase were cell mass and PHB, while in stationary phase, SMP were accounted for>30 % of the substrate electrons utilized. In general, the largest portion of SMP comprised low-molecular weight (<3 kDa) compounds mostly pro-duced during stationary phase

Exploiting the fact that sensor nodes are stationary and location-aware, TTDD constructs and maintains the grid structures
July 1965 M. Sankar-Rao 41 7 ON THE INFLUENCE OF THE VERTICAL DISTRIBUTION OF STATIONARY HEAT SOURCES AND SINKS IN THE ATMOSPHERE
"... Within the framework of a quasi-geostrophic model, the influence of different kinds of vertical profiles of diabatic heating on a stationary harmonic of the atmosphere is studied. Except in the cases in which there is a diabatic heating reversal in the upper layers of the atmosphere, the results sho ..."
