A New Proposed Handoff Scheme for Mobile Communication Systems
There are many studies dealt with handoff management in mobile communication systems and some of these studies presented handoff schemes to manage this important process in cellular network. All previous schemes used relative signal strength (RSS) measurements. In this work, a new proposed handoff scheme had been presented depending not only on the RSS measurements but also used the threshold distance and neighboring BSS power margins in order to improve the handoff management process. We submitted here a threshold RSS as a condition to make a handoff when a mobile station moves from one cell to another this at first, then we submitted also a specified margin between the current received signal and the ongoing BSs received signal must be satisfied in order to transfer opening call within new cell, finally we submitted again a threshold distance to exceed by a mobile station in order handoff process is done. The purpose of all these thresholds is to decrease the unnecessary handoffs that can be happened and causing either handoff delayed or call dropped. Our simulation results illustrated that the new proposed scheme is sufficiently improved the handoff process with reducing the unnecessary handoffs as compared with other schemes.
