D-Bridge: A platform for developing low-cost WSN product solutions

Today the construction of wireless sensing systems requires the use of rather high-priced pieces of hardware and the assembly of these hardware parts (wireless transmission core, sensor module, gateway device), as well as the implementation of the according software (sensor mote software, gateway software, end user software). This makes overall development and the thereby resulting product costly in terms of both time and money. With the D-Bridge concept that we present in this paper we will show an approach that is much cheaper than any other solution in terms of hardware and development costs. This D-Bridge is a combination of a gateway between the wireless sensor network and the IP network which also includes a Web-based application server at the wireless sensor network appliance´s location.
