  Abstract

The host mobility manages the movement of each mobile user individually, whereas the network mobility supports the movement of network which is composed of a set of mobile users. SIP-NEMO, that is one of the network mobility management mechanism, is designed using the application layer protocol. SIP-NEMO has a merit in deployment and scalability. It can also mitigate the existing problems of NEMO. However, when a user agent is disconnected from the NMS which plays a role of a gateway in SIP-NEMO, the service interruption time can be increased because the user agent should re-establish the connection by performing all service connection procedure. To solve this problem, we propose an efficient session recovery procedure for NEMO that a user agent re-establishes a connection by using IP address of parent-NMS or AR to decrease a service interruption time, the message overhead and the packet loss amount. The performance evaluation results have shown that the proposed mechanism can reduce a service interruption time about 35 percent, it can reduce the message overhead and packet loss amount.
