In 4G cellular system, due to the mobility, proper handoff or handover management is critical to ensure seamless migration from one cell to another cell. Besides of maintaining the connection quality during a handover process, any advanced handover algorithms which can minimize required resources for the connection are critical. When connections need to migrate between heterogeneous networks for performance and high-availability reasons, seamless vertical handoff (between different access technologies) is a necessary first step. In this paper, the authors try to simulate vertical handoff with a dynamic decision according to the Received Signal Strength (RSS); and they build a self-learning, self-optimization and self-organization to make the best decision by using Artificial Neural Network (ANN) and Fuzzy Junction Computation (FJC).
