Compact Wakeup Scheduling in Wireless Sensor Networks
In a traditional wakeup scheduling, sensor nodes start up numerous times to communicate in a period, thus consuming extra energy due to state transitions (e.g. from the sleep state...

A Global Constraint for Total Weighted Completion Time
We introduce a novel global constraint for the total weighted completion time of activities on a single unary capacity resource. For propagating the constraint, an O(n4 ) algorithm...

MIMO Downlink Weighted Sum Rate Maximization with Power Constraints per Antenna Groups
Abstract— We consider a single-cell multiple-input multipleoutput (MIMO) downlink channel where linear transmission and reception strategy is employed. The base station (BS) tran...

Capacity Scaling of Wireless Networks With Inhomogeneous Node Density: Lower Bounds
Abstract-- We consider static ad hoc wireless networks comprising significant inhomogeneities in the node spatial distribution over the area, and analyze the scaling laws of their ...

Application-Driven Node Management in Multihop Wireless Sensor Networks
A strategy for energy saving in wireless sensor networks is to manage the duty cycle of sensors, by dynamically selecting a different set of nodes to be active in every moment. We ...
