ABSTRACT
Transfering the paradigm of service-oriented architecture (SOA) to sensor networks became an important research area in the last years. Amongst others, a couple of approaches deal with the flexible and robust service discovery and usage of services which takes the unsteady nature of WSNs into account. However, the approaches do not consider the case that services may get unavailable during their activity phase because of node failures. In this case, already collected or computed data will get lost and the service request of the service consumer remains unanswered. In this paper, we propose a redundancy infrastructure for service-oriented WSNs which deals with this special problem. The framework consists of an adaptive data replication technique and a service recovery solution. Whereas the replication technique ensures the survival beyond node failures, the recovery protocol restarts a failed service using the replicated data and enables the service to continue its functionality.
