An Efficient Utilization of Spectrum in Seamless Mobility by Using Retransmission Rerouting Mechanism in Mobile IP

Abstract

Without an iota of doubt, the aspect of seamless mobility has become an important characteristic for high-fidelity wireless communication. As handy and trendy cell phones / smart phones are primarily used for the communication purpose, the cell coverage zones are mandated to be of high quality and adaptively to make and receive calls with all clarity and confidence. Usually, the seamless mobility capability is being achieved through the automatic handover from one cell to another under certain situations. The aspect of automatic handover is the process of adaptively changing the connection linkage established and being currently used to another connection even when the user is still talking. This channel shift is initiated often when crossing a borderline of the cell or if there is a substantial downturn in the receiving signal quality in the current channel. Mobile IP too has to reinforce the redirect the data to new foreign agent after the access of the network changes according to a particular sequence to hold up the seamless mobility. In this case, there is an additional delay caused by the redirection and in some cases, retransmission of the original data. The ideal case is therefore that the service interruption has to be extremely minimal to ensure the quality of experience (QoE). Therefore minimizing the unwanted delay handover process is being insisted everywhere for keeping up the connectivity anytime and anywhere across communication networks.
