Abstract
The use of wireless sensor networks as a means for providing remote healthcare has the potential to radically change our nation's approach to healthcare, spurring a transition from a clinic-oriented, centralized service provider paradigm to a patient-oriented, distributed healthcare system. There remain, however, significant obstacles to the use of sensor networks in a medical context. In particular, the ability to recover from failures and maintain an acceptable level of service degradation despite of failures is a crucial aspect in the design of remote healthcare systems. This paper investigates the fault tolerate routing and restoration solutions that can provide the performance assurance for the life-critical patient monitoring service despite of various failures. In particular, we consider three strategies, namely global restoration, end-to-end restoration, and local restoration, which can support a range of tradeoffs between the restoration latency and network utilization. We formulate the routing restoration problem under these three strategies as linear programming problems and build their solutions into CareNet, a two-tier wireless sensor network environment for remote healthcare. Extensive experiments are conducted to validate and evaluate our design.
