Building an efficient bus management system (BMS) is necessary to help reducing the congestion in urban transportation and providing the passenger convenience. Its communication network demands the collection of real-time information from the buses to the control center of BMS and offers various useful information for passengers and bus drivers. DSRC (Dedicated Short Range Communication) is applied...
The CPU scheduler algorithm of XEN has been widely used in some real-time systems, but it cannot balance the loading in multi-processor system. Based on the relationship between cache and memory in SMP, this paper illustrates an algorithm with a shared waiting queue. According the loading status of each CPU, this algorithm can dynamically adjust the scheduling order of the VCPUs. Our simulation results...
