ABSTRACT
Large-scale wireless sensor networks are composed of
hundreds or thousands of autonomous sensor nodes. How
to manage wireless sensor networks effectively is a big
challenge. This paper presents a hierarchical management
architecture for wireless sensor networks. In contrast to
previous management architecture on wired networks and
wireless ad-hoc networks, this architecture is based on
wireless sensor networks' two distinct features:
centralization and task orientation. Based on such
architecture, the paper also develops a lightweight, taskoriented
clustering algorithm to reduce the granularity of
wireless sensor networks. The simulation demonstrates its
effectiveness in wireless sensor network based on energy
analysis.
Keywords- Wireless Sensor Networks, Task
Orientation, Scalability, Light Weighting
I. INTRODUCTION
Wireless sensor networks have been identified as one of
the most important technologies for the 21st century [1].
The current and potential applications of sensor networks
cover a wide range, including environment monitoring,
military sensing, emergency medical care, industrial and
manufacturing remote control, mechatronics and
automation [1][2]. Such a big diversity of applications
poses huge challenges to the effective management of
wireless sensor networks.
"Even though management of sensor networks is a nontrivial
task, this area has been left largely untouched."[3]
Recent research on the management of wireless sensor
networks has mainly focused on the topology and
connectivity [4] [5]. In 1993, A. Leinwand and K. Fang
refer to network management as "A process of controlling
a complex data network so as to maximize its efficiency
and productivity" [6]. The International Standards
Organization (ISO) divides the network management into
five areas: fault management, configuration management,
security management, performance management, and
accounting management [7]. Especially, most wireless
sensor nodes are powered by battery rather than external
power, so that energy conservation is a key issue for the
design and implementation of wireless sensor networks.Consequently, energy management becomes a special and
important aspect of wireless sensor network management.
