Next-generation mobile terminals are expected to provide users with seamless, uninterrupted network connectivity while moving across wide geographic locations. Achieving continuous network access is made possible by exploiting multi homing in mobile nodes and providing support for several heterogeneous network interfaces. Efficient mechanisms are required to enable mobile nodes to connect to various available networks to improve connectivity and provide network resilience. Stream Control Transmission Protocol (SCTP) has been proposed as a potential candidate for facilitating multiple network support to achieve smooth session continuity while moving across different types of networks. This paper presents a comparative analysis of reliability of network protocols against Service Failure Threats. Remote Monitoring Systems have recently emerged as a solution to provide mission critical services to remote areas across the geographic boundaries. Such systems demand for high level of reliability and quality in terms of un-interrupted service. The paper highlights limitations of traditional network protocols like TCP and standard SCTP and highlights the need of multi-homing devices. Performance of multi-homing SCTP (MH-SCTP) has been analyzed against Service failure threats. Simulation performed on test bed created in NS-2 show that MH-SCTP outperforms TCP and standard SCTP in terms of better throughput and reduced no. of dropped packets. Such a service will also provide quality long-term healthcare services in the healthcare enterprise.
