Handoff in Heterogeneous Wireless Networks Using Vertical Handoff Decision Algorithm
Among the key issues of Next-Generation Wireless Networks (NGWN), mobility management is one of the most crucial. Because, to providing the seamless connection in the heterogeneous wireless networks, the seamless roaming especially for real time applications is providing is very difficulty. The proliferation of wireless technologies and their ever increasing popularity Mobile Terminals (MTs) equipped with a myriad of network interfaces. It is then becoming essential to offer vertical handoff solutions where users can move among various network types efficiently and seamlessly. A variety of mechanisms supporting vertical handoffs by selecting the best possible network interfaces.
