摘要:The performances of the handover through the heterogeneous networks play a crucial role for OoS-sensitive applications and real-time services. Although, NEMO BS protocol has the merit to allow today the deployment and the experimentation of non-temporal constraints services, without having to function in a degraded mode, its performances (high latency, high packet loss and the important signaling cost) are clearly non-optimal and consequently it is considered non-suitable for time constraints applications. Several architectures and mechanisms were proposed to optimize the performances of NEMO handover. However, these optimizations remain insufficient to meet the needs for the applications to critical performance. This paper proposes a mobility support for multihomed NEMO networks when several mobile routers are deployed. A proactive approach consisting in carrying out soft handover (Make Before Brake) is adopted, leading to the availability of several tunnels simultaneously which will be used according to the management of mobility. A performance evaluation under NS2 making it possible to validate the model suggested is envisaged
