The wide rang's traffic control system manages various traffic subsystems which has different structure and function, its information platform is a typical heterogeneous distributed system. In order to integrate these traffic subsystems, a mutual information platform needs to be established and the mobile agent technology provides a new method of building the information platform. This paper first...
The traditional sampling test method is fit for cases that the number of sample is greater than thirty. A sample statistics is proposed for the sampling test of maximum maintenance time, which the maintenance time is normally distributed. Based on the non-central t-distribution, the distribution function of the sample statistics is deduced. And a sampling test method of maximum maintenance time is...
To improve the localization precision based on RSSI ranging in wireless sensor networks, a localization method based on the ranging-error compensation is presented. By analyzing the tendency of RSSI ranging error with different distance, we propose the mathematical model and the experiment results about ranging-error compensation. It is proved that the method based on ranging-error compensation effectively...
