Design And Implementation Of Wireless Sensor Network Test System Based On Proprietary Protocol

With the continuous development of wireless sensor network technology, wireless sensor networks are widely used in various fields. Building a wireless sensor network test platform to monitor the performance of wireless’ sensor networks has a sense of practical application.This paper designs and implements a wireless sensor network test systems based on proprietary protocol which is designed for very special needs of users to test network layer protocol. Wireless senor network test system based on proprietary protocol has characteristics of high reliability of data acquisition, online fault detection and second-level network performance computing. The main works are summarized below:1) By investigating and analyzing the way of data collection in domestic and foreign test system, this paper presents a highly reliable way of data collection. The data collection is a passive data collection. The test system can not send any commands to the being monitored network, minimizes the interference to the being monitored network and ensures the authenticity of the data.2) In this paper, the communication link is unstable and node prone to failure and other issues, proposes and implementes an online fault detection. This paper improves the existing fault detection algorithm based on neighbor nodes, simulations show that the fault detection rate and errorRate of alarm of the improved algorithms has been improved.3) This paper presents a second-level network performace computing, the server of the test system computes the perpormance of the network every second (including topology, throughtput, errorRate, lossRate and etc.) and sends the results to client which achieves a nearly real-time updates of the performance.In later work, the paper will add the test of the remaining power node and survival time of network, and will display the network topology based on the actual location of the nodes.
