IPv4/IPv6 transition mechanisms for ubiquitous wireless sensor networks monitoring

The wireless sensor networks (WSN) concept was appeared in the middle of 90´s and have been a subject under intensive research in the past few years. Several factors have contributed to this; the most important is the vast potential for application of WSNs in almost every aspect of day-to-day life is the predominant one. These networks have been developed using proprietary approaches instead of standard solutions. More recently, the importance of standards motivated the use of IETF standards in WSNs, making the Internet integration easier. The dissemination of small mobile devices with Internet connectivity can be the drive to the WSN growth, because user-friendly applications maybe used to retrieve and collect sensed data. This paper proposes a solution based on REST Web services to support the interaction between a mobile application and the IPv6 compliant WSN. Dual stack mechanisms are supported in order to accept requests from both IPv4 and IPv6 mobile devices. A WSN laboratory testbed was deployed to perform the validation and demonstration of the proposed solution.
