- The population of mobile communication subscribers keeps increasing exponentially with a growing industrial interest in the provision of improved quality of service. To maintain quality of service in a heterogeneous network built for high capacity utilization, the communication network must be stable as mobile users interact within the implemented coverage distribution. One of the basic mechanisms behind this communication metric is its ability to communicate wirelessly with respect to changing locations. Mobility is one critical benefit of mobile communication, which is made possible through the process of Handoff. One of the key performances in mobile communication is Handoff failure (call termination) rate, which is dependent critically on the handoff initiation mechanism. In this paper, the effect of traditional single parameter of either signal-to-noise ratio (SNR) or throughput on handover threshold and hysteresis was investigated. Consequently, a cross layer enhanced adaptive handoff initiation algorithm using fuzzy logic was proposed. The proposed method exploits the capability of soft computing to handle the unpredictable nature of the radio propagation environment. Four critical handoff Network-link parameters were employed to vary the Handoff threshold and Hysteresis in test the adaptive functionality of the algorithm. The proposed algorithm was seen to be adaptive to throughput, SNR, mobile transmitting power (MTP) and mobile velocity, thereby resulting in improved quality of service, marked with a decrease in handoff failure probability rate.
