IMPLEMENTATION OF DYNAMIC SMART DECISION MODEL FOR VERTICAL HANDOFF

Abstract

International Mobile Telecommunications-Advanced (IMT Advanced); better known as 4G is the next level of evolution in the field of wireless communications. 4G Wireless networks enable users to access information anywhere, anytime, with a seamless connection to a wide range of information and services, and receiving a large volume of information, data, pictures, video and thus increasing the demand for High Bandwidth and Signal Strength. Wireless heterogeneous networks like CDMA, WLAN, GPRS are the mediums or technologies that users use to get information. The mobility among various networks is achieved through Vertical Handoff. Vertical handoffs refer to the automatic failover from one technology to another in order to maintain communication. The heterogeneous co-existence of access technologies with largely different characteristics creates a decision problem of determining the “best” available network at “best” time for handoff. In this major project thesis, we implemented the pr...
