移动计算中2种呼叫接入控制优化策略的分析与比较
Analysis and comparison of two optimized call admission control schemes in mobile computing environment
摘要
Abstract
After two optimized call admission control schemes known as DT−CAC and RBDO−CAC were presented,the performances of these two schemesatdifferent call traffic intensitieswere tested using NS−2, and compared with traditional NCB scheme.Theresults show that both DT−CAC and RBDO−CAC can achieve better performancesthan NCB. On the whole,when compared with DT−CAC,RBDO−CAChas lowerhandoff call dropping probability and new call blocking probability, and higher system resource utilization rate. The system resource utilization rate under high call traffic load of RBDO−CAC can be 2%−5%higher thanDT−CAC.关键词
