| 摘 要： | 针对WLAN/蜂窝异构网络的特点,提出了基于层次分析法的网络切换判决算法。算法综合考虑了网络状态及用户业务特征,分别采用SAW法和TOPSIS法对网络组合权向量进行了计算,仿真表明基于层次分析法的TOPSIS法与SAW法相比,更适合时延敏感业务的网络切换判决。

| Abstract: | For WLAN/cellular network, a handoff decision algorithm was proposed based on analytic hierarchy process.Considering the network status and user’s traffic features, SAW and TOPSIS are simulated in the proposed algorithm.Compared with SAW,simulation results show that the analytic hierarchy ana is with TOPSIS is more suitable for network handoff decision of delay sensitive applications. |

| Keywords: | handoff decision analytic hierarchy process heterogeneous networks SAW TOPSIS |
