In recent years it has become evident that mobility support will have profound impact on current and future wireless networks. Users expect service connectivity at any place at anytime without having to think about the underlying communication systems used in that particular moment in time. On this background, this paper presents a ready to deploy implementation of a mobility framework that supports seamless communication and represents an important enabler for adaptive applications through its simple QoS feedback mechanism. The framework selects the best available network through a decision algorithm that takes advantage of a link performance monitoring concept. The performance evaluation of the proposed framework is also presented in this paper.
