Ant Colony Optimization Based Handoff Scheme and Verifiable Secret Sharing Security with M-M Scheme for VoIP

Abstract

Voice over Inter Protocol (VoIP) empowers in the integration of voice data over IP networks, minimizing the cost of network transmission for helping users of IP protocol. Robust and effective procedure of handoff is introduced for increasing the quality and the dependability of the networks. Ant Colony Optimization (ACO) is presented for the handoff mechanism and Mean Opinion Score (MOS) is observed to be the fitness value for obtained measurements of the assessment of voice quality. In this research, the scheme of Multiplex-Multicast (M-M) is proposed that will improve the capability of VoIP in WLAN to 100% in the form of an infrastructure Basic Service Set (BSS). This research work deals with the security features of VoIP in order to enhance the quality making use of Verifiable Secret Sharing (VSS) with the help of M-M scheme. The M-M scheme will eliminate the downlink VoIP traffic ineffectiveness through the multiplexing of the packets from different VoIP streams into one multicast packet for transmitting over the WLAN. The results from simulation indicate the advancements in the security enhancements making use of the proposed schemes. The average Round Trip Time (RTT) results of the proposed VSS with M-M are 0.30436 milliseconds, whereas average RTT is 0.3598 milliseconds and 0.43604 milliseconds for VSS and Shamir SS methods respectively. It concludes that the proposed VSS with M-M takes lesser RTT results when compared to existing methods.
