| 英文摘要: |
| An essential characteristic of the 4th Generation (4G) wireless networks is integrating various heterogeneous wireless access networks. This paper considers the network selection for both admission and handoff strategy problems in heterogeneous network of 3G/WLAN. A novel dynamic programming algorithm is proposed by taking heterogeneous network characteristics, user mobility and different service types into account. The specificity of our approach is that it puts the situations in a new model and makes decisions in stages of different states. Simulation results validate that the proposed scheme can obtain better new call blocking and handoff dropping probability performance than traditional schemes while ensuring quality-of-services (QoS) for both real-time and data connections. |
