Driven by business needs for faster and more accurate information an increasing number of sensor network solution providers have recently entered the marketplace. These are solutions which provide node information beyond classic RFID or barcodes. The number of bi-directional high resolution sensor offerings increases daily. Most are targeted to niche markets but are not built to integrate with upstream applications such as SCM or ERP.
Sensor network solutions usually consist of distributed autonomous sensors that are connected with each other and via a gateway to an IP network. In most cases, vendors offering sensor network hardware solutions also offer a software solution to manage the sensors and their generated data. Most of the interfaces and protocols of the gateways or the software solutions are vendor specific.
