Semi-active handover algorithm assisted on location for heterogeneous wireless networks

This paper illustrates a semi-active handover algorithm on the integrated utilization of RSS and location, according to characteristics of a cellular network and WiFi. While connecting to a cellular network, MS (Mobile Station) is in the passive mode, where BS (Base Station) informs the MS to hand over on the basis of location information. In contrast, MS in the WiFi link chooses the optimal AP (Access Point) or switches to the cellular network in light of the detection algorithm proposed by this paper. The final emulation could prove the semi-active mechanism to effectively prevent the occurrence of a ping-pong effect, and improve performance to the right network.
