Selecting Vertical Handover Candidates in WLAN Hotspots
نویسندگان
چکیده
Future wireless networks will consist of multiple heterogeneous access technologies such as UMTS, WLAN, and WiMax. These technologies differ greatly regarding medium access scheme, network capacity, QoS support, choice of data rates, and other various parameters such as power consumption and AAA aspects. In the literature, different network access selection and handover strategies have been discussed in order to maximize the utilization for such a heterogeneous network. Thereby, it is still an open issue how to select ”inefficient” mobiles as vertical handover candidates. This work presents a novel scheme for the selection of handover candidates in WLAN hotspots. After discussing the design rationale of the decision metric, simulation studies show the impact of single and multiple handovers on remaining users in the cell.

متن کاملSoft, Vertical Handover of Streamed Video
The delay and jitter of an RTP stream transported by TCP over WLAN are examined as candidates for assisting handover between networks. Jitter was found to be a good indicator of when a mobile is close to the edge of a WLAN cell and was used to spawn a vertical handover mechanism. The implemented handover scheme used an averaged delay difference to complete the handover of the video stream.

The ability to access information while on the move has become a necessity for most business users. The 3G cellular networks, like UMTS, promise to offer always on, ubiquitous connectivity to users with relatively high mobility, but with relatively low data rate. On the contrary WLANs offer much higher data rates but with low er mobility coverage. The complementary characteristics of the 3G and...

Much of interest has been involved in integrating UMTS and WLAN networks in order to take full advantage of the two. In such an integrated network, UMTS subscribers can access to UMTS services through 3G or WLAN access networks. This is highly desirable because network operators will use WLAN hotspots to increase network coverage, while offering subscribers with high-speed connections to 3G net...
