Abstract

The need to stay connected to the Internet ''anytime'' and ''anywhere'' is becoming more and more required in the recent years with the development of wireless networks. The NEMO basic support protocol was developed to grant the Internet connection for an entire mobile network, like vehicle or aircraft network. In NEMO a Mobile Router manages the mobility of the entire network on behalf of the other nodes in order to reduce the overhead of signaling messages. The critical part of mobility support is to reduce the handover latency, particularly when a Mobile Router is not reachable. This handover period degrades the performance of most delay sensitive applications. Referring to our proposition for NEMO handover improvement which is conceived for multiple-mobile-routers-based multihomed NEMO network, we find out a mathematical model to study the intradomain handover performance. We derive the mathematical model to analyze interruption interval (the time interval during which none of mobile routers can transport packets) during the intradomain handover. We study the impact of varying critical parameters, like vehicle speed, overlapping coverage distance, distance between mobile routers, and scanning frequency. The obtained results reveal that the seamless handover can be achieved if network configuration parameters are correctly chosen.
