Seamless interconnection of WSN and internet

The future internetworking is envisioned to develop concepts that can autonomously interact with the physical world. Wireless Sensor Network (WSN) technology is considered as the defacto concept which is the bridge to the real world. So, this technology should be adapted to support interoperability with the commodity Internet. This is not a straightforward process because the technological background of these networks do not fit each other. Hence, seamless interconnection between WSN and the IP networks is a challenging research problem. In this experimental study, proxy-based and gateway-based approaches to the solution are analyzed and a hybrid approach which combines the advantages of them is defined. The proposed approach is used to build a web server for WSNs. The overall performance of the new server and its adaptation layer is tested on a real testbed with a series of experiments. The early results obtained in this study are very encouraging. Thus, further analysis is needed towards a seamless interconnection architecture for WSNs.
