Research on real-time performance improvement of embedded wireless network measurement and control platform

Using the self-designed embedded wireless network measurement and control platform as application object, this paper puts forward and takes three real-time measures improving system followed. The first step is to transplant μ C/OS-II, strong real-time operating system to improve the real-time response speed of the master node of the network center; the second step is to adopt the time-limited communication scheduling strategy of the nodes to reduce the waiting and delaying time of most nodes of the network. The third is to open the DuoCeiver mechanism to ensure that the urgent nodes are preferentially able to get service. The running results demonstrated these means are feasible and have effectively improved system´s real-time capability.
