    An Extensive Proposal for Vertical Handoff Technique in WLAN

    Vertical handoff is the one of the most powerful hidden weapon of the wireless network scenario. As the whole world of digital electronics is moving towards internet of things as result of this vertical handoff becomes a much needed seamless connectivity tool to enhance the paradigm. Now a days many of the digital electronic devices are been inventing to boost the smaller networks like in office, universities and companies. So an inverse arise of need for vertical handoff in the WLAN is on much priority like never before. Many of the systems are existed to provide vertical handoff without degrading or interrupting the data access facility in WLAN. In most of the vertical handoff mechanism the load is put on the mobile nodes to look over the data flow mechanism in the established WLAN. This may add some contribution to increase the delay in the delivery of the data in the established network. So as an efficient answer to this, this paper put forwards an idea of vertical handoff mechanism using the pool manger in the network and put the burden on the mangers to take care of the handoff process, so that the data delivery rate can be increased. This process is designed based on the tile (i.e. time) in the said pool (pool tile vertical handoff – PTVHO) which is catalyzed by fuzzy logic to measure the handoff parameters efficiently
