Abstract
The next generation wireless network is aimed to provide users with anywhere, anytime, and seamless service. With the increasing demand for the next generation network, many research works have focused on the efficient way to integrate different types of heterogeneous wireless networks such as cellular systems and wireless LAN. Therefore, the network selection technique plays a critical role in ensuring quality of service for the next generation network. In this paper, we propose an adaptive network selection (ANSWER) scheme, which is able to make the better decision about when to switch and choice on which access network. That is, we want to provide the always-best-connected service as much as possible for the users. Specifically, to achieve the above goals, the available bandwidths of all possible networks, the location of user’s device and its moving direction are taken into consideration in the ANSWER approach. We evaluate the performance of the ANSWER scheme through extensive simulations and the results agree with our goals.
