Abstract

With the recent advances in wireless sensor network technology, wireless 
sensor networks (WSN) are widely deployed in many industrial and civilian 
applications, such as military application, energy management, health 
care, environment monitoring and etc. Most of these applications require 
the deployment of large-scale WSN. Due to the limitation of sensor nodes, 
few of them could provide user interface. Thus, it is difficult to monitor 
the operation of the sensor nodes within a WSN. In some applications, the 
whole system consists of thousands of sensor nodes. How to guarantee the 
performance of such systems would be a great challenge. One method to 
avoid the problem raised in operating such large scale system is to 
conduct extensive testing by an experiment tool in the real environment. 
If the developer could obtain energy consumption of the sensor nodes and 
topology info of the whole sensor system, the performance of the large 
scale WSN system can be fully monitored.
	
We design a WSN monitoring system, which can be deployed out to detect the 
communication and sensing data in WSN. In this system, a script engine is 
designed to analysis the row data. And a schema is designed to ensure the 
monitoring info sequence under low powerful hardware system. After that, 
we will discuss an application of wireless sensor network, to monitor the 
channel boundary in a typical area. We provide an idea, which is called 
sensing channel assignment algorithm (SCAS). It can improve the 
effectiveness of wireless spectrum in WSN. Simulation results will show 
that the sensitivity and accuracy are quite good.
