Vertical handoff decision in heterogeneous wireless networks

Abstract

The growing consumer demand for access to communication newlineservices anywhere and anytime is accelerating the technological development newlinetowards the integration of various wireless technologies such as WiFi newlineWiMAX and cellular systems called as Fourth Generation 4G wireless newlinesystems 4G wireless systems provide higher data rates high speed and allow newlineglobal roaming among a diverse range of wireless access networks In such a newlineheterogeneous wireless environment one of the key ingredients to provide newlineefficient ubiquitous computing with guaranteed quality and continuity of newlineservice is the design of an intelligent vertical handoff algorithm newline newline
