Abstract

Fourth Generation (4G) wireless systems include the integration of many wireless technologies including Wi-Fi, WiMAX, and cellular networks in order to meet the rising need for mobile and always-on access to communication services. Higher data rates, increased speed, and international roaming across many wireless access networks are key benefits of 4G wireless systems. One of the most important aspects of providing effective ubiquitous computing in a heterogeneous wireless environment is the creation of a smart vertical handoff algorithm that ensures the quality and continuity of service. particular significant issues within the larger field of vertical handoff are tackled here, with a focus on making effective use of the system characteristics to accomplish particular application-specific goals. This research presents a fresh method for developing a vertical handoff algorithm that takes into account many criteria in heterogeneous wireless networks.
