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.

Abstract-We present a comprehensive survey of Voice over IP security academic research, using a set of 245 publications forming a closed cross-citation set. We classify these papers according to an extended version of the VoIP Security Alliance (VoIPSA) Threat Taxonomy. Our goal is to provide a roadmap for researchers seeking to understand existing capabilities and to identify gaps in addressing the numerous threats and vulnerabilities present in VoIP systems. We discuss the implications of our findings with respect to vulnerabilities reported in a variety of VoIP products.We identify two specific problem areas (denial of service, and service abuse) as requiring significant more attention from the research community. We also find that the overwhelming majority of the surveyed work takes a black box view of VoIP systems that avoids examining their internal structure and implementation. Such an approach may miss the mark in terms of addressing the main sources of vulnerabilities, i.e., implementation bugs and misconfigurations. Finally, we argue for further work on understanding cross-protocol and cross-mechanism vulnerabilities (emergent properties), which are the byproduct of a highly complex system-of-systems and an indication of the issues in future large-scale systems.

Abstract-Several voice over internet protocol (VoIP) providers migrate to their services to session initiation protocol (SIP). SIP is a lightweight signaling protocol used to implement in wiled VoIP services. However, with the global spread of this service, we can see how VoIP is affected by the stealing of SIP trunk services. Thus, the VoIP Trade Company will exhaust it effort and income. Our survey shows how much SIP security is enforced when somebody cracks the SIP server, and looks for any VoIP process trunk IP to use the server as a legitimate user, or to try to harm the trunk by injecting it with a forged source code that will lead to a road map for the hacker. The latter will make it deny the server, or inject it with the SQL script effect to come with DDos attacks. Our study shows the interest of researchers and students on VoIP security. It also provides a road map between the hypotheses and implementation, particularly on how SIP is affected by the variety of attacks from the outside world and from inside the local network.
