Fuzzy Logic Based Decision Making Algorithm to Optimize the Handover Performance in HetNets

Abstract

A prominent growth in a wireless communication system provides a wide range of services for a heterogeneous wireless network thus accomplishing user's needs. These real time services are delay sensitive which requires a continuous internet connec-tion. Assuring a seamless end-end connectivity without link outages at the mid of an action is a crucial ongoing problem. Thus the main objective relies on designing a cognitive algorithm to achieve the practical impossibility of having a sustainable net connection while roaming across various technologies. Hence, to fulfill this and de-grade vertical handover (VHO) issues an enhanced fuzzy logic based algorithm is proposed. Further, it focuses on improving the transmission quality with low han-dover latency, less packet loss and reduced false handover. Along with this the algo-rithm achieves an accurate prediction in the decision making of an optimal network to which the idle node gets connected. The networking environment also has an effi-cient mobility management, where the functioning network controls the mobility of concerned mobile nodes. Finally the simulation process of this proposal on a com-prehensive test-bed infers the fuzzy logic based algorithm, guaranteed seamless con-nection. Further, the system has a 1.6% improvement in reducing the handover delay and 1.3% in packet loss reduction than the existing approaches, which in turn im-proves the transmission quality.
