Integrating SIP with F-HMIPv6 to Enhance End-to-End QoS in Next Generation Networks

Abstract

With the advancement in communication technologies, user’s demand continuously increases while moving across diverse networks. The research community is putting their best efforts in the deployment of Next Generation Networks (NGNs). The primary goal of NGNs is to provide Always Best Connected (ABC) services. Researchers’ current focus is on many issues such as support for multicasting and QoS, security, resource management and allocation, location coordination and handoff. In such a heterogeneous environment, ensuring the end-to-end QoS is a challenge. The problem in combining Session Initiation Protocol (SIP) with Mobile IPv6 and Seamless MIPv6 is that the traffic goes through core network every time the call/ sessions are established, resulting into very high delay and overhead on core networks. In this paper, integrating SIP with Fast handover for Hierarchical Mobile IPv6 (ISF) is proposed which utilizes the balancing capabilities of each protocol and endeavors at dropping their practical dependencies. ISF ensures end-to-end QoS for multimedia session as well as minimizing the signaling traffic between edge and core networks, service disruption, and user authentication. The conducted results show that our proposed scheme outperforms the existing approaches in terms of handover latency, packet loss, and packet load.
