A novel dynamic service architecture for RFID and WSNS applications

A novel dynamic service architecture used to integrate radio-frequency identification (RFID) and wireless sensor networks (WSNs) is proposed according to requirements on the ubiquitous computing. An infrastructure used to monitor devices and collect data at real time is proposed, which constitutes with monitor service and container service. The monitor service provides the mechanism based on service meta-model for dynamic deploying and fault-tolerance. The container service provides lifecycle management and runtime environment for sensors application services. An algorithm used to schedule and deploy application services dynamically is proposed, which is based on QoS capabilities provided by compute resource, such as CPU speed, memory capability and bandwidth. The results show that the service schedule approach is remarkable.
