Reliable Resource Management for IoT based Logistic Services

Since IoT sensor nodes have narrow bandwidth and fault-prone wireless channels, sensor-based logistics systems are subject to incomplete data services. The surest way to minimize the this unstable service is data replication at multiple sensor nodes. In this study, we propose a replica management scheme called Bridged Replication Control(BRC) in order to achieve sufficient data accessibility in fault-prone moving sensor networks such as smart logistics. BRC provides temporary opportunity of replica access even to the disconnected wireless cell and handles the access opportunity via one temporary privilege called WLanBridge token. Since BRC has a generic functionality of efficient data management for mobile sensor devices, it can be widely employed in IoT service networks.
