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 connection.
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 degrade vertical handover (VHO) issues an enhanced
fuzzy logic based algorithm is proposed. Further, it focuses on improving the
transmission quality with low handover latency, less packet loss and reduced
false handover. Along with this the algorithm 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 efficient mobility management, where the
functioning network controls the mobility of concerned mobile nodes. Finally
the simulation process of this proposal on a comprehensive test-bed infers the
fuzzy logic based algorithm, guaranteed seamless connection. 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 improves the
transmission quality.
