Abstract Mobility management is evolving as the most astounding area of research for the upcoming researchers. Many issues such as signalling overhead, latency, low bandwidth, low reliability, etc., existed in traditional mobility schemes in wireless networks. But the next-generation heterogeneous networks have resolved many issues and researchers are looking forward to take best use of upcoming generations to provide constant connectivity. In this paper, a fuzzy logic-based adaptive threshold and adaptive hysteresis handoff initialisation algorithm is proposed. It uses data rate, received signal strength indicator and SINR to determine the value of threshold and hysteresis. This algorithm makes use of Okumura Hata Path loss model to determine the value of RSSI, which is then given to fuzzy inference engine. It has been shown that threshold and hysteresis are not only dependent on RSSI but also on many other parameters such as on transmitter height, receiver height and antenna gain, frequency and cable loss.
