The rapid growth of wireless networks and services, integrated with the next-generation mobile communication systems, has led to designing efficient handoff protocols to handle m...
We consider setting up sleep scheduling in sensor networks. We formulate the problem as an instance of the fractional domatic partition problem and obtain a distributed approximati...
— In this paper we consider the problem of constructing a coordinate system in a sensor network where location information is not available. To this purpose we introduce the Virt...

Abstract-- We address the problem of batching messages generated at nodes of a sensor network for the purpose of reducing communication energy at the expense of added latency. We f...
In this paper we present an online algorithm that attacks the problem of placing relay nodes in regions where high localized congestion is detected. Congestion refers to the netwo...
