An increasing number of research efforts on wireless sensor networks (WSNs) are now considering dynamic environments with heterogeneous sensor devices. Most of this research considers data, control, and management issues separately and not clearly within a common architecture. This paper presents our development of an architecture, namely DCM-Arch, to address these issues together. The architectureconsists...
There is a large body of work addressing information storage, reduction, and dissemination in Wireless Sensor Networks (WSNs), but there seems to be no contribution giving a survey of this literature. In this paper we take on such a challenge and review previous WSN research and further presents a framework that we use for classifying the different proposed approaches and techniques. The framework...
Sensor networks usually generate continuous stream of data over time. Clustering sensor data as a core task of mining sensor data plays an essential role in analytical applications of sensor networks. Although several algorithms have been proposed to address the problem of distributed clustering, in the domain of sensor networks these algorithms face major new challenges such as limited communication...
Wireless sensor networks (WSNs) are increasingly used as an enabling technology in a variety of domains. They operate unattended in an autonomous way, are inherently error prone and have limited resources like energy and bandwidth. Due to these special features and constraints, the management of sensor nodes in WSNs has its own unique technical challenges as well. For example, system software for...
The low resource availability in the nodes of recent wireless networks has raised several new issues in the design of their hardware and software components. One of the high level approaches for optimizing resource usage in these networks is to reduce the number of communications among wireless nodes. In this paper, we propose a new paradigm for optimizing the number of data transmissions between...
