In the development of the wireless communication of the future, mobility management and existing heterogeneous wireless networks integration in next generation or 4G wireless networks are developing trend. Such an environment poses a significant challenge: how can we choose an appropriate Network Access Point (NAP) to achieve load balance and offer high quality communication in heterogeneous wireless handover decisions? However, mobility management as well as the integration and interworking are a complex task due to their specific characteristics. This paper we apply fuzzy logic in heterogeneous wireless network handover decisions and introduce the fuzzy normalization concept to make parameters for heterogeneous wireless network normalization. Using a simulation, we determine under what conditions our handover decision algorithm can balance network system loading better than the traditional fuzzy algorithms applied in heterogeneous wireless network handover decisions.
