The contribution of this paper is threefold. First, we give tight bounds for the complexity of the
problem of data aggregation in static networks. In more details, we show that the problem …

We study the problem of minimizing data aggregation time in wireless sensor networks
(WSNs) under the practical duty-cycle scenario where nodes switch between active states …

The key feature of wireless sensor networks is to aggregate data collected by individual
sensors in an energy efficient manner. We consider two techniques to save energy. The first …

Data aggregation is one of the challenging issues in Wireless Sensor Networks (WSNs).
Traditionally, sensor nodes are assumed to be in the active state all the time, which leads to …

We consider the problem of aggregating data in a dynamic graph, that is, aggregating the
data that originates from all nodes in the graph to a specific node, the sink. In our model …

In the problem under consideration it is necessary to find a schedule of conflict-free data
aggregation of a minimum length, ie to determine the transmission moments for each vertex …

In existing studies, the problem of maximizing aggregation information based on a given
particular tree in deadline-and energy-constrained unreliable wireless sensor networks was …
