For seamless handover in heterogeneous wireless networks, service continuity and minimal handover disruption time are the primary requirements. The emerging Media Independent Handover (MIH) standard proposes to address these requirements through the introduction of link performance prediction features. In particular the MIH Event Service introduces a Link_Going_Down event which utilizes L2 performance characteristics to trigger predictive events. While the MIH standard proposes a framework by which L2 events can be communicated to the upper layer, it does provide detail on the performance characteristics which trigger these events. In this paper, we design a MIH based Velocity Optimized Seamless Handover Mechanism …

For patients who have undergone cardiovascular surgery it is necessary to monitor vital signs such as respiration, oxygen in the blood, temperature, and electrocardiogram (ECG) in real time. As well as the sensor device, many existing solutions need a bulky coordinating unit like a PDA located on the patient for network communication. In this paper we investigate an infrastructure mode based approach in which the wireless sensor, communicates directly with the wireless access point. Our investigation particularly focuses on how the emerging technology, Media Independent Handover (MIH) can be used by the wireless sensor to manage path migration. Since MIH …
