Throughput during handoff and suits well for supporting real-time applications to mobile users. Handoff delay and packet loss when compared with previous approaches and was able to maintain 90% Simulation and analytical results show that, the proposed solution shows an improvement of 44% in terms of We have alsoĪnalyzed the IMS pre-registration delay and IMS session re-setup delay based on Queuing theory. Have simulated these scenarios using NS2 and the performance characteristics are studied. IMS session re-setup delay in a WiFi/WiMax heterogeneous environment by defining new SIP messages. Prior-SIP(P-SIP) with a cross layer scheme utilizing Media Independent Handover (MIH) services to reduce the (CA) - based Pre-registration approach to reduce the IMS Re-registration delay and a novel scheme called In this paper, we propose two SIP based schemes, a Context Aware In the conventional Session initiation Protocol (SIP), handoff performance is very poorĭue to high handoff delay and packet loss. Process during vertical handoff (VHO) is still a major bottleneck for Voice Over IP (VoIP) and interactive The delay incurred due to IP Multimedia subsystem (IMS) re-registration and session re-setup IndiaĮmail: Providing fast and seamless handoff in a pervasive computing environment is one of the recent Research Scholar, Anna University, Coimbatore.
