Minimization of Handoff Failure Probability for Next-Generation Wireless Systems

During the past few years, advances in mobile communication theory have enabled the development anddeployment of different wireless technologies, complementary to each other. Hence, their integration canrealize a unified wireless system that has the best features of the individual networks. Next-GenerationWireless Systems (NGWS) integrate different wireless systems, each of which is optimized for somespecific services and coverage area to provide ubiquitous communications to the mobile users. In thispaper, we propose to enhance the handoff performance of mobile IP in wireless IP networks by reducingthe false handoff probability in the NGWS handoff management protocol. Based on the information offalse handoff probability, we analyze its effect on mobile speed and handoff signaling delay.
