Abstract: Heterogeneous 4G wireless networks are the next generation of wireless networks which connect various wireless networks of different technologies. Heterogeneous networks have to handle both horizontal and vertical handovers. Vertical handover is one of the critical issues of 4G wireless networks that has to be handled intelligently in order to maintain seamless connectivity over the 4G network. This study introduces an intelligent, congestion aware and media independent handover mechanism for the 4G heterogeneous wireless network. The algorithm makes direct handover in less congested situations and uses fuzzy logic and neural network based approach to take the handover decision when there is congestion in the network. The algorithm performs better with reduced latency and increased bandwidth in all situations and also performs with gain in terms of load, power and cost.
