A study on disruption tolerant session based mobile architecture

Abstract

There are lots of Challenges while using IP mobility. Among that route optimization and frequent handover is most important. Preserving communication between two moving end points on the Internet is difficult. For efficient mobility multiple access points are needed, so frequent handover is always needed for getting appropriate access points. Handling mobility will leads to performance degradation. Also unexpected disconnection is problematic for session-based applications which maintains state and consume resources. Thus stability and connectivity are the notable challenges for a smooth data transmission in the mobile environment. A disruption Tolerant Session based Mobile Architecture is a method suitable to solve these problems. A Disruption tolerant Session based Mobile Architecture is a solution that allow minimum disconnection time to enable seamless mobility. This architecture is a TCP based Application suitable for secure connection establishment, reliable end to end transmission. The session scheme used in the architecture allows mobility for TCP-based applications which need flexibility to failures, delays or disconnection and also provides session services, such as tracking mobile nodes, detecting disruptions, and suspending and resuming sessions with efficiency, security, and reliability. By using this architecture disruptions can be detected in microseconds and recovery takes only milliseconds.
