Paper Abstract:
|
For patients suffering from cardiovascular conditions it is imperative that alterations to vital signs such as respiration,
oxygen in the blood, temperature and ECG are detected in real time. In addition to the sensor device, many existing
solutions require a mobile device such as a mobile phone for network communication. In this paper, we propose an
infrastructure mode based approach in which the sensor itself communicates directly with the wireless access network. In
such a configuration, the network path migration strategy is critical since the loss, delay or corruption of data can have
fatal consequences. An emerging technology which proposes to provide the ability to detect and initiate handover from
one network to another without loss is Media Independent Handover (MIH). Since MIH does not implement the physical
handover we also use the mobility enabled Stream Control Transmission Protocol (SCTP). We analyze how MIH
performance characteristics, in particular Received Signal Strength (RSS), can be used to improve SCTP switchover in
body sensor network environments. |
