Service-Oriented Transparent Interconnection between Data-Centric WSN and IP networks
Hua Cao, Jiazhong Chen · 2010
Wireless sensor networks (WSN) have been recently be proposed for great deal of applications in industrial automation, health and environment monitoring. Increasingly there is a need to access wireless sensor networks from other IP-based networks. However, WSN has its own application-specific non-standardized protocols such as data-centric router protocol, which is a significant challenge to establish interconnection with IP networks which is based on address-centric router protocols. Service-Oriented Architecture (SOA) has been chosen to implement the communication among distributed applications. In this paper, we propose a Service-Oriented framework for inter-connection between data-centric WSN and IP network. This framework enables service-based query for data-centric WSN based on Device Profile for Web service (DPWS). It provides transparent access from one network to the other without modifying protocols running in either network.
