Generic vertical handover prediction algorithm for 4G wireless networks

Vertical handover predictions require intelligent algorithm to coordinate heterogeneous access technologies in the 4G-communication system. Although much attention is being given to the handover architecture in most of the literatures, little is mentioned about estimating user movement and prediction for improving the reliability of the access of the underlying system architecture. In an effort to reduce the data loss probability, the Generic Prediction Algorithm (GPA) adopts specimens of received signal strength (RSS) as augment to compute the predictive received signal strength. Received signal strength (RSS), bandwidth (BW), and service cost (SC) are three QoS metrics considered as input parameters for Quantitative Decision Algorithm (QDA) of the divergent networks. The comparison of values of QDA of the networks is made to improve the vertical handover decision. A result of simulation shows that the algorithm proposed produces a better network performance in terms of link reliability.
