Measurement Mechanism of IP Performance Metrics for Network Mobility

This paper proposes a measurement mechanism of IP performance metrics for network mobility (NEMO) in heterogeneous wireless networks. The key idea of the proposed mechanism is that mobile nodes (MNs) can get IP performance metrics irrespective of the presence or absence of measurement functionality. That is, the proposed mechanism does not require MNs to be involved in measuring IP performance metrics because the multihomed mobile router (MMR) with heterogeneous wireless interfaces measures IP performance metrics on behalf of the MNs inside the mobile network. MNs can get measured IP performance metrics from the MMR using L3 messages. Therefore, the proposed mechanism can reduce burden and power consumption of MNs with limited resource and battery power since MNs don't measure directly IP performance metrics. In addition, the proposed mechanism can reduce considerably traffic overhead over wireless links on multiple measurement paths since signaling messages and injected testing traffic are reduced.
